Pleural cavity Parietal Visceral Pleural Fluid: prevents pleural friction rub
(as seen in pneumonia and pleural effusion)
- Provides for reoxygenation of blood and release of CO2
PULMONARY ARTERIES, carry blood from the heart to the lungs.
PULMONARY VEINS, is a large blood vessel of the circulatory system that carries blood from the lungs to the left atrium of the heart.
RESPIRATORY MUSCLES- PRIMARY: diaphragm and external intercostal muscles- ACCESORY: sternocleidomastoid (elevated sternum), the
scalene muscles (anterior, middle and posterior scalene) and the nasal alae

PHYSIOLOGY OF RESPIRATORY SYSTEM
VENTILATION: The movement of air in and out of the airways.
• The thoracic cavity is an air tight chamber. the floor of this chamber is the diaphragm.
• Inspiration: contraction of the diaphragm (movement of this chamber floor downward) and contraction of the external intercostal muscles increases the space in this chamber. lowered intrathoracic pressure causes air to enter through the airways and inflate the lungs.
• Expiration: with relaxation, the diaphragm moves up and intrathoracic pressure increases. this increased pressure pushes air out of the lungs. expiration requires the elastic recoil of the lungs.
• Inspiration normally is 1/3 of the respiratory cycle and expiration is 2/3.
DRIVING FORCE FOR AIR FLOWAirflow driven by the pressure difference between atmosphere
(barometric pressure) and inside the lungs (intrapulmonary pressure).
AIRWAY RESISTANCE
Resistance is determined chiefly by the radius size of the airway.
Causes of Increased Airway Resistance1. Contraction of bronchial mucosa2. Thickening of bronchial mucosa3. Obstruction of the airway4. Loss of lung elasticity
RESPIRATION• The process of gas exchange between atmospheric air and
the blood at the alveoli, and between the blood cells and the cells of the body.
• Exchange of gases occurs because of differences in partial pressures.
• Oxygen diffuses from the air into the blood at the alveoli to be transported to the cells of the body.
• Carbon dioxide diffuses from the blood into the air at the alveoli to be removed from the body.
NEUROCHEMICAL CONTROLMEDULLA OBLONGATA – respiratory center initiates each breath by sending messages to primary respiratory muscles over the phrenic nerve
- has inspiration and expiration centers
PONS – has 2 respiration centers that work with the inspiration center to produce normal rate of breathing1. P NEUMO T A X IC CEN T ER – affects the inspiratory effort by limiting the volume of air inspired2. A P NEUS T IC CEN T ER – prolongs inhalation
NOTE: Chemoreceptors responds to changes in ph, increasedPaCO2 = increase RR
RESPIRATORY EXAMINATION AND
ASSESSMENT
Background information
A. Abnormal patterns of breathing1. Sleep Apnea
cessation of airflow for more than 10 seconds more than 10 times a night during sleep
causes: obstructive (e.g. obesity with upper narrowing, enlarged tonsils, pharyngeal soft tissue changes inacromegaly or hypothyroidism)
2. Cheyne-Stokes periods of apnoea alternating with periods of
hyperpnoae pathophysiology: delay in medullary chemoreceptor
response to blood gas changes causes
left ventricular failure brain damage (e.g. trauma, cerebral,
haemorrhage) high altitude
3. Kussmaul's (air hunger) deep rapid respiration due to stimulation of respiratory
centre causes: metabolic acidosis (e.g. diabetes mellitus,
chronic renal failure)4. Hyperventilation
complications: alkalosis and tetanycauses: anxiety
5. Ataxic (Biot)irregular in timing and deepcauses: brainstem damage
6. Apneusticpost-inspiratory pause in breathingcauses: brain (pontine) damage

7. Paradoxical the abdomen sucks with respiration (normally, it
pouches uotward due to diaphragmatic descent) causes: diaphragmatic paralysis
B. Cyanosis1. Refers to blue discoloration of skin and mucous
membranes , is due to presence of deoxygenated haemoglobin in superficial blood vessels
2. Central cyanosis = abnromal amout of deoxygenatedhaemoglobin in arteries and that blue discoloration is present in parts of body with good circulation such as tongue
3. Peripheral cyanosis = occurs when blood supply to acertain part of body is reduced, and the tissue extracts more oxygen from normal from the circulating blood, e.g. lips in cold weather are often blue, but lips are spared
4. Causes of cyanosis
Central cyanosis decreased arterial saturation
decreased concentration of inspired oxygen:high altitude
lung disease: COPD with cor pulmoale, massive pulmonary embolism
right to left cardiac shunt (cyanotic congenitalheart disease)
polycythaemia haemoglobin abnromalities (rare):
methaemoglobinaemia, sulphaemoglobinaemia
Peripheral cyanosis all causes of central cyanosis cause peripheral
cyanosis exposure to cold reduced cardiac output: left ventricular failure or shock arterial or venous obstruction
Position: patient sitting over edge of bed
General appearance
look for the following Dyspnea
normal respiratory rate < 14 each minute tachypnoea = rapid respiratory rateare accessory muscles being used (sternomastoids, platysma, strap muscles of neck) - characteristically, the accessory muscles cause elevation of shoulders with inspiration and aid respiration by increasing chest expansion
Cyanosis Character of cough
ask patient to cough several timeslack of usual explosive beginning may indicate vocal cord paralysis (bovine cough)
muffled, wheezy ineffective cough suggests airflow limitation
very loose productive cough suggests excessive bronchial secretions due to:
- chronic bronchitis- pneumonia- bronchiectasis
dry irritating cough may occur with:- chest infection
- asthma- carcinoma of bronchus- left ventricular failure- interstitial lung disease- ACE inhibitors
Sputumvolumetype (purulent, mucoid, mucopurulent)presence or absence of blood?
Stridorcroaking noise loudest on inspiration is a sign that requires urgent attentioncauses: (obstruction of larynx, trachea or large broncus)
- acute onset (minutes) inhaled foreign body acute epiglottitis anaphylaxis toxic gas inhalation
- gradual onset (days, weeks) laryngeal and pharyngeal tumours crico-arytenoid rheumatoid arthritis bilateral vocal cord palsy tracheal carcinoma paratracheal compression by lymph nodes post-tracheostomy or intubation
granulomata Hoarseness
causes include:- laryngitis- laryngeal nerve palsy associated with
carcinoma of lung- laryngeal carcinoma
The Hands
Clubbing commonly cause by respiratory disease (but NOTemphysema or chronic bronchitis)
occasionally, clubbing is associated with hypertrophic pulmonary osteoarthropathy (HPO) characterised by periosteal inflammation at distal ends
of long bones, wrists, ankles, metacarpals and metatarsals
sweelling and tenderness over wrists and other involved areas
Staining staining of fingers - sign of cigarette smoking (caused by tar, not
nicotine) Wasting and weakness Pulse rate Flapping tremor (asterixis) - unreliable sign
ask patient to dorsiflex wrists and spread out fingers, with arms outstretched
flapping tremor may occur with severe carbon dioxide retention (severe chronic airflow limitation)

Eyes Horner's syndrome? (constricted pupil, partial ptosis and loss
of sweating which can be due to apical lung tumourcompressing sympathetic nerves in neck)
Nosepolpys? (associated with asthma)engorged turbinates? (various allergic conditions)deviated septum? (nasal obstruction)
Mouth and tonguelook for central cyanosisevidence of upper respiratory tract infection (a reddened pharynx and tonsillar enlargement with or without a coating of pus)
broken tooth - may predispose to lung abscess or pneumonia
sinusitis is indicated by tenderness over the sinuses on palpation
some patients with obstructive sleep apnoea will be obesewith a receding chin, a small pharynx and a short thick neck
The Trachea
causes of tracheal displacement: toward the side of the lung lesion
upper lobe collapse upper lobe fibrosis pneumonectomy
upper mediastinal masses, such as retrosternal goitre tracheal tug (finger resting on trachea feels it move inferiorly with
each inspiration) is a sign of gross overexpansion of thechest because of airflow obstruction
The Chest: inspection
Shape and symmetry of chest Barrel shaped
anteroposterior (AP) diameter is increased comparedwith lateral diameter
causes: hyperinflation due to asthma, emphysema
Pigeon chest (pectus carinatum) localised prominence (outward bowing of sternum and
costal cartilages) causes:
manifestation of chronic childhood illness (due to repeated strong contractions of diaphragm while thorax is still pliable)rickets
Funnel chest (pectus excavatum) developmental defect involving a localised depression
of lower end of sternum in severe cases, lung capacity may be restricted
Harrison's sulcus innar depression of lower ribs just above costal margins
at site of attachment of diaphragm causes:
severe asthma in childhood rickets
Kyphosis , exaggerated forward curvature of spineScoliosis , lateral bowingKyphoscoliosis: causes: idiopathic (80%) secondary to poliomyelitis (inflammation involving grey
matter of cord) (note: severe thoracic kyphoscoliosis may reduce lung
capacity and increase work of breathing)
Lesions of chest wall scars - previous thoracic operations or chest drains for a
previous pneumothorax or pleural effusion thoracoplasty (was once performed to remove TB, but no
longer is because of effective antituberculosis chemotherapy) invovled removal of large number ofribs on one side to achieve permanent collapse of affected lung
erythema and thickening of skin may occur in radiotherapy; there is a sharp demarcation betweenabnormal and normal skin
Diffuse swelling of chest wall and neck pathophysiology: air tracking from the lungs causes:
pneumothoraxrupture of oesopahagus
Prominent veins cause: superior vena caval obstruction
Asymmetry of chest wall movements assess this by inspecting from behind patient, looking
down the clavicles during moderate respiration - diminished movement indicates underlying lung disease
the affected side will showed delayed or decreased movement
causes of reduced chest wall movements on one side are localised:
localised pulmonary fibrosis consolidationcollapsepleural effusion pneumothroax
causes of bilateral reduced chest wall movements are diffuse:

The Chest: palpation
chest expansion place hands firmly on chest wall with fingers extending
around sides of chest (fugyre 4.5) as patient takes a big breath in, the thumbs should move
symmetrically apart about 5 cm reduced expansion on one side indicates a lesion on that side note: lower lobe expansion is tested here; upper lobe is
tested for on inspection (as above) apex beat
(discussed in cardiac section)for respiratory diseases:
displacement toward site of lesion - can be caused by:collapse of lower lobe localised pulmonary fibrosis
displacement away from site of lesion - can be causedby:
pleural effusion tension pneumothorax
apex beat is often impalpable in a chest which ishyperexpanded secondary to chronic airflow limitation
vocal fremitus palpate chest wall with palm of hand while patient repeats
"99" front and back of chest are each palpated in 2 comparable
positions with palms; in this way differences in vibration on chest wall can be detected
causes of change in vocal fremitus are the same as those for vocal resonance (see later)
ribsgently compress chest wall anteroposteriorly and laterally localised pain suggests a rib fracture (may be secondary to trauma or spontaneous as a result of tumour deposition or bone disease)
The Chest: percussion
with left hand on chest wall and fingers slightly separated and aligned with ribs, the middle finger is pressed firmly against the chest; pad of right middle finger is used to strike firmly the middle phalanx of middle finger of left hand
percussion of symmetrical areas of: anterior (chest) posterior (back) (ask patient to move elbows forward across
the front of chest - this rotates the scapulae anteriorly, i.e. moves it out of the way)
axillary region (side) supraclavicular fossa
percussion over a solid structure (e.g. liver, consolidated lung)produces a dull note
percusion over a fluid filled area (e.g. pleural effusion)produces an extremely dull (stony dull) notepercussion over the normal lung produces a resonant note percussion over a hollow structure (e.g. bowel, pneumothorax) produces a hyperresonsant note
liver dullness: upper level of liver dullness is determined by percussing down
the anterior cehst in mid-clavicular line normally, upper level of liver dullness is 6th rib in right
mid-clavicular line if chest is resonant below this level, it is a sign of
hyperinflation usually due to emphysema, asthma
cardiac dullness: area of cardiac dullness is uaully present on left side of chest this may decrease in emphysema or asthma
The Chest: auscultation
breath sounds introduction
one should use the diaphragm of stethoscope to listen to breath sound in each area, comparing each side remember to listen high up into the axillaeremember to use bell of stethoscope to listen to lung from above the clavicles
quality of breath sounds
normal breat sounds are heard with stethoscope over all parts of
chest, produced in airways rather than alveoli (although once they had been thought to arise from alveoli (vesicles) and are therefore called vesicular sounds)
normal (vesicular) breath sounds are louder and longer on inspiration than on expiration; and there is no gap between the inspiratory and expiratory sounds
bronchial breath sounds turbulence in large airways is heard without being
filtered by the alveoli, and therefore produce a different quality; they are heard over the trachea normally, but not over the lungs
are audible throughout expiration, and often there is a gap between inspiration and expiration
are heard over areas of consolidation since solid lung conducts the sound of turbulence in main airways to peripheral areas without filtering
causes include:- lung consolidation (lobar pneumonia) -
common- localised pulmonary fibrosis - uncommon- pleural effusion (above the fluid) -
uncommon- collapsed lung (e.g. adjacent to a pleural
effusion) - uncommon amphoric sound = when breath sounds over a large
cavity have an exaggerated bronchial quality) intensity of breath sounds
causes of reduced breath sounds include: chronic airflow limitation (especially
emphysema) pleural effusion pneumothorax pneumonia large neoplasm pulmonary collapse
added (adventitious) sounds two types of added sounds: continuous (wheezes) and
interrupted (crackles)
wheezes may be heard in expiration or inspiration or both pathophysiology of wheezes - airway narrowing an inspiratory wheeze implies severe airway
narrowing

New Era University – College of NursingMENTORING ACTIVITY: SY 2014-2015
Mentee: Patricia Joy Guinto, Batch 2016Mentor: Leslie Masaya, Batch 2015
causes of wheezes include:- asthma (often high pitched) - due to muscle
spasm, mucosal oedema, excessivesecretions
- chronic airflow diseases - due to mucosal oedema and excessive secretions The Abdomen
pulmonary thromboembolism marked obesitysleep apnoeasevere kyphoscoliosis
- carcinoma causing bronchial obstruction -tends to cause a localised wheeze which is monophonic and does not clear with coughing
Other
palpate liver for enlargement due to secondary deposits of tumour from lung, or right heart failure
crackles some terms not to use include rales (low pitched
crackles) and creptitations (high pitched crackles)
crackles are due to collapse of peripheral airways on expiration and sudden opening on inspiration
early inspiratory crackles- suggests disease of small airways- characteristic of chronic airflow limitation- are only heard in early inspiration
late or paninspiratory crackles- suggests disease confined to alveoli- may be fine, medium or coarse- fine crackles - typically caused by
pulmonary fibrosis- medium crackles - typically caused by left
ventricular failure (due to presence ofalveolar fluid)
- coarse crackes - tend to change with coughing; occur with any disease that leadsto retention of secretions; commonly occurin bronchiectasis
pleural friction rub when thickened, roughened pleural surfaces rub
together, a continuous or intermittent grating sound may be heard
suggests pleurisy, which may be secondary to pulmonary infarction or pnuemonia
vocal resonanancegives information about lungs' ability to transmit sounds consolidated lung tends to transmit high frequencies so that speech heard through stethoscope takes a bleeting quality (aegophony); when a patient with aegophony says "bee" it sounds like "bay"
listen over each part of chest as patient says "99"; over consolidated lung, the numbers will become clearly audible; over normal lung, the sound is muffled
whispering pectoriloquy - vocal resonance is increased to such an extent that whispered speech is distinctly heard
The Heart
lie patient at 45 degreesmeasure jugular venous plse for right heart failure examine preacordium; pay close attention to pulmonary component of P2 (which is best heard at 2nd intercostal space on left) and should not be louder than A2; if it is louder, suspect pulmonary hypertension
cor pulmonale (also called pulmonary hypertensive heart disease) may be due to:
chronic airflow limitation (emphysema)pulmonary fibrosis
Permberton's sign ask patient to lift arms over head look for development of facial plethora, inspiratory
stridor, non-pulsatile elevation of jugular venous pressure
occurs in vena caval obstruction
Feet inspect for oedema or cyanosis (clues of cor
pulmonale) look for evidence of deep vein thrombosisd
Respiratory rate on exercise and positioning patients complaining of dyspnoea should have their
respiratory rate measured at rest, at maximal tolerated exertion and supine
if dyspnoea is not accompanied by tachypnoea when a patient climbs stairs, one should consider malingering
look for paradoxical inward motion of abdomenduring inspiration when patient is uspine (indicating diaphragmatic paralysis)
Temperature: fever may accompany any acute or chronic chest infection
DIAGNOSTIC EVALUATION
1. Skin Test: Mantoux Test or Tuberculin Skin Test
This is used to determine if a person has been infected or has been exposed to the TB bacillus.
This utilizes the PPD (Purified Protein Derivatives). The PPD is injected intradermally usually in the inner aspect
of the lower forearm about 4 inches below theelbow.
The test is read 48 to 72 hours after injection. ( + ) M a n t o u x T e st is induration of 10 mm or more. But for HIV positive clients, induration of about 5 mm is
considered positive Signifies exposure to Mycobacterium Tubercle bacilli
This is the direct inspection and observation of thelarynx, trachea and bronchi through a flexible or rigidbronchoscope.
Passage of a lighted bronchoscope into the bronchialtree for direct visualization of the trachea and thetracheobronchial tree.
This chest CT scan shows a cross-section of a person
Diagnostic uses: To examine tissues or collect secretions
with bronchial cancer. The two dark areas are the lungs. The lightareas within the lungs represent the cancer.
To determine location or pathologic processand collect specimen for biopsy

2. Pulse Oximeter Non-invasive method of continuously monitoring he
oxygen saturation of hemoglobin A probe or sensor is attached to the fingertip, forehead,
earlobe or bridge of the nose Sensor detects changes in O2 sat levels by monitoring light
signals generated by the oximeter and reflected by the blood pulsing through the tissue at the probe
Normal SpO2 = 95% - 100% < 85% - tissues are not receiving enough O2 Results unreliable in:
Cardiac arrest Shock Use of dyes or
vasoconstrictors Severe anemia High carbon
monoxide Level
3. Chest X-ray
This is a NON-invasive procedure involving the use of x- rays with minimal radiation.
The nurse instructs the patient to practice the on cue tohold his breath and to do deep breathing
Instruct the client to remove metals from the chest. Rule out pregnancy first.
5. Computed Tomography (CT Scan) and Magnetic ResonanceImaging ( MRI )
The CT scan is a radiographic procedure that utilizes x-ray machine.
The MRI uses magnetic field to record the H+ density of the tissue.
It does NOT involve the use of radiation.The contraindications for this procedure are the following: patients with implanted pacemaker, patients with metallic hip prosthesis or other metal implants in the body.
Clear MRI images of lung airways during breathing.
6. Flouroscopy Studies the lung and chest in motion Involves the continuous observation of an image reflected
on a screen when exposed to radiation in themanner of television screen that is activated by an electrode beam.
Structures of different densities that intercept the X-ray beam are visualized on the screen in silhouette
7. Indirect Bronchography A radiopaque medium is instilled directly into the
trachea and the bronchi and the outline of the entire bronchial tree or selected areas may be visualizedthrough x-ray.
It reveals anomalies of the bronchial tree and is important in the diagnosis of bronchiectasis.
Nursing interventions BEFORE Bronchogram Secure written consent Check for allergies to sea foods or iodine or
anesthesia NPO for 6 to 8 hours Pre-op meds: atropine SO4 and valium, topical

14. Arterial Blood Gas Laboratory test Indicate respiratory functions Assess the degree to which the lungs are able to provide
adequate oxygen and remove CO2 Assess the degree to which the kidneys are able to
reabsorb or excrete bicarbonate. Assessment of arterial blood for tissue oxygenation,
ventilation, and acid-base status Arterial puncture is performed on areas where good
pulses are palpable (radial, brachial, or femoral).Radial artery is the most common site for withdrawal of blood specimen
Nursing interventions: Utilize a 10-ml. Pre-heparinized syringe to
prevent clotting of specimen Soak specimen in a container with ice to
prevent hemolysis If ABG monitoring will be done, do Allen’s
test to assess for adequacy of collateral circulation of the hand (the ulnar arteries)
15. Pulmonary Angiography This procedure takes X-ray pictures of the pulmonary blood
vessels (those in the lungs). Because arteries and veins are not normally seen in an X- ray, a
contrast material is injected into one or morearteries or veins so that they can be seen.
Turn on the unaffected side to prevent leakage The nurse should prevent skin breakdown by checkingof fluid in the thoracic cavity nares, nose and applying gauze or cotton as necessary
Check the puncture site for fluid leakage Ensure that COPD patients receive only LOW flow Auscultate lungs to assess for pneumothorax oxygen because these persons respond to hypoxia, not Monitor oxygen saturation (SaO2) levels increased CO levels.

16. Ventilation - Perfusion Scan Radioactive albumin injection is part of a nuclear scan
test that is performed to measure the supply of blood through the lungs.
After the injection, the lungs are scanned to detect the location of the radioactive particles as blood flowsthrough the lungs.
The ventilation scan is used to evaluate the ability of air to reach all portions of the lungs. The perfusion scan measures the supply of blood through the lungs.
A ventilation and perfusion scan is most often performed to detect a pulmonary embolus. It is also used to evaluate lung function in people with advanced pulmonary disease such as COPD and to detect the presence of shunts(abnormal circulation) in the pulmonary blood vessels.
17. Thoracentesis Procedure suing needle aspiration of intrapleural fluid or
air under local anesthesia Specimen examination or removal of pleural fluid
Nursing intervention BEFORE Thoracentesis Secure consent Take initial vital signs Instruct to remain still, avoid coughing during
insertion of the needle Inform patient that pressure sensation will be
felt on insertion of needle
Nursing intervention DURING the procedure: Reassess the patient Place the patient in the proper position:
Upright or sitting on the edge of the bed
Lying partially on the side, partially on the back
Nursing interventions after Thoracentesis Assess the patient’s respiratory status Monitor vital signs frequently Position the patient on the affected side, as
ordered, for at least 1 hour to seal the puncturesite
RESPIRATORY CARE MODALITIES
1. Oxygen Therapy Oxygen is a colorless, odorless, tasteless, and dry gas that
supports combustion Man requires 21% oxygen from the environment in order to
survive Indication: Hypoxemia
Signs of Hypoxemiao Increased pulse rateo Rapid, shallow respiration and dyspneao Increased restlessness or lightheadednesso Flaring of nareso Substernal or intercostals retractionso Cyanosis
Low flow oxygen provides partial oxygenation with patient breathing a combination of supplemental oxygen and room air. Low-flow administration devices:

2. Tracheobronchial suctioning Suction only when necessary not routinely Use the smallest suction catheter if possible Client should be in semi or high Fowler’s position Use sterile gloves, sterile suction catheter Hyperventilate client with 100% oxygen before and after
suctioning Insert catheter with gloved hand (3-5― length of catheter
insertion) without applying suction. Three passes of the catheter is the maximum, with 10 seconds per pass.
Apply suction only during withdrawal of catheter The suction pressure should be limited to less than 120
mmHg When withdrawing catheter rotate while applying
intermittent suction Suctioning should take only 10 seconds (maximum of 15
seconds) Evaluate: clear breath sounds on auscultation of the chest.
3. Bronchial Hygiene Measures Suctioning: oropharyngeal; nasopharyngeal
a. Steam inhalation
Goals are removal of bronchial secretions, improved ventilation, and increased efficiency of respiratory muscles. Postural drainage uses specific positions to use gravity to assist
in the removal of secretions. Vibration loosens thick secretions by percussion or
vibration. Breathing exercises and breathing retraining improve
ventilation and control of breathing and decrease the work of breathing.
These are procedures for patients with respiratory disorders like COPD, cystic fibrosis, lung abscess, and pneumonia. The therapy is based on the fact that mucus can be knocked or shaken from airways and helped todrain from the lungs.
Postural drainage Use of gravity to aid in the drainage of secretions. Patient is placed in various positions to promote flow of
drainage from different lung segments using gravity. Areas with secretions are placed higher than lung
segments to promote drainage. Patient should maintain each position for 5-15 minutes
depending on tolerability.
b. Aerosol inhalation done among pediatric clients to administer brochodilators or
mucolytic-expectorants..
c. Medimist inhalation done among adult clients to administer bronchodilators or
mucolytic-expectorants.
4. Chest Physiotheraphy ( CPT ) Includes postural drainage, chest percussion and vibration, and
breathing retraining. Effective coughing is also an important component.

Suctioning Nursing Interventions in CPT
Verify doctor’s order Assess areas of accumulation of mucus secretions. Position to allow expectoration of mucus secretions by
gravity Place client in each position for 5-10 to 15 minutes Percussion and vibration done to loosen mucus
secretions Change position gradually to prevent postural
hypotension Client is encouraged to cough up and expectorate
sputum Procedure is best done 60 to 90 minutes before
meals or in the morning upon awakening and at bedtime.
Provide good oral care after the procedure
5. Incentive Spirometry• Types: volume and flow• Device ensures that a volume of air is inhaled and the
patient takes deep breaths.• Used to prevent or treat atelectasis• To enhance deep inhalation
• Nursing care– Positioning of patient, teach and encourage use, set
realistic goals for the patient, and record the results.
6. Closed Chest Drainage ( Thoracostomy Tube ) Chest tube is used to drain fluid and air out of the
mediastinum or pleural space into a collection chamberto help re-establish normal negative pressure for lung re- expansion.
Purposes To remove air and/or fluids from the pleural space To reestablish negative pressure and re-expand the
lungs Procedure
The chest tube is inserted into the affected chest wall at the level of 2nd to 3rd intercostals space to release air or in the fourth intercostals space to remove fluid.
Types of Bottle DrainageOne-bottle system
The bottle serves as drainage and water-seal Immerse tip of the tube in 2-3 cm of sterile NSS to
create water-seal. Keep bottle at least 2-3 feet below the level of the
chest to allow drainage from the pleura by gravity. Never raise the bottle above the level of the heart to
prevent reflux of air or fluid. Assess for patency of the device Observe for fluctuation of fluid along the tube. The
fluctuation synchronizes with the respiration. Observe for intermittent bubbling of fluid;
continues bubbling means presence of air-leak
In the absence of fluctuation:Suspect obstruction of the device
Assess the patient first, then if patient is stable Check for kinks along tubing; Milk tubing towards the bottle (If the hospital allows the nurse
to milk the tube) If there is no obstruction, consider lung re-expansion;
(validated by chest x-ray) Air vent should be open to air.
Two-bottle system If not connected to the suction apparatus The first bottle is drainage bottle; The second bottle is water-seal bottle Observe for fluctuation of fluid along the tube
(water-seal bottle or the second bottle) and intermittent bubbling with each respiration.
NOTE! IF connected to suction apparatus1. The first bottle is the drainage and water-seal bottle;2. The second bottle is suction control bottle.3. Expect continuous bubbling in the suction control bottle;4. Intermittent bubbling and fluctuation in the water-seal5. Immerse tip of the tube in the first bottle in 2 to 3 cm of
sterile NSS6. Immerse the tube of the suction control bottle in 10 to 20 cm
of sterile NSS to stabilize the normal negativepressure in the lungs.
7. This protects the pleura from trauma if the suction pressure is inadvertently increased

If there is NO f l u c t u a t io n i n t h e w a ter s ea l bo t t l e , it may meanTWO things
Either the lungs have expanded or the system is NOTfunctioning appropriately.
In this situation, the nurse refers the observation to the physician, who will order for an X-ray to confirm the suspicion.
Important Nursing considerations Encourage doing the following to promote drainage: Deep breathing and coughing exercises Turn to sides at regular basis Ambulate ROM exercise of arms Mark the amount of drainage at regular intervals Avoid frequent milking and clamping of the tube to
prevent tension pneumothorax
What the nurse should do if: If there is continuous bubbling: The nurse obtains a toothless clamp Close the chest tube at the point where it exits the chest for a
few seconds. If bubbling in the water seal bottle stops, the le a k is
l i ke l y in t h e l un g s , But if the bubbling continues, the le a k is b e tw ee n t h e c l a m p
a n d t h e b o t t le c h a m b e r .
Next, the nurse moves the clamp towards the bottle checking the bubbling in the water seal bottle.
If bubbling stops, the leak is between the clamp and the distal part including the bottle.
But if there is persistent bubbling, it means that thedrainage unit is leaking and the nurse must obtain another set.
In the event that the water seal bottle breaks, the nurse temporarily kinks the tube and must obtain areceptacle or container with sterile water and immerse the tubing.
She should obtain another set of sterile bottle as replacement. She should NEVER CLAMP the tubefor a longer time to avoid tension pneumothorax.
In the event the tube accidentally is pulled out, the nurse obtains vaselinized gauze and covers the stoma.
She should immediately contact the physician.
a. Oral airways- these are shorter and often have a larger lumen.They are used to prevent the tongue form falling backward.
b. Nasal airways- these are longer and have smaller lumen Which causes greater airway resistance
c. Tracheostomy- this is a temporary or permanent surgical opening in the trachea. A tube is inserted to allow ventilation and removal of secretions. It is indicated for emergency airway access for many conditions. The nurse must maintain tracheostomy care properly to prevent infection.
