What is CPAP?
Continuous
Positive
Airway
Pressure
![Page 7: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/7.jpg)
Why CPAP
• Better for the patient
• Reduction in morbidity and mortality
• Less invasive then intubation
• Less complications than intubation
• Reduction in pre-hospital intubation
• Reduction in length of stays and ICU admissions
• It’s cost effective
![Page 8: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/8.jpg)
What are we using CPAP for?
• The treatment of respiratory distress secondary to Congestive Heart Failure (CHF)
• Other Respiratory Conditions: • Pneumonia • Asthma • COPD
![Page 9: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/9.jpg)

Anatomy & Physiology Review
![Page 16: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/16.jpg)
![Page 17: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/17.jpg)
Respiratory Cycle
• Two Phases • Inspiration • Expiraton
![Page 18: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/18.jpg)
Inspiration
• Active process requiring muscles to have energy and function
• Diaphragm and intercostal muscles contract
• Diaphragm moves downward
• Ribs move upward and outward
• Increased chest size allows air to flow into the lungs (less pressure inside)
![Page 19: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/19.jpg)
Exhalation
• Passive process allowing muscles to relax
• Diaphragm rises
• Ribs moves downward and inward decreasing chest cavity size
• Smaller chest size allows air to flow out of the lungs (less pressure outside)
![Page 20: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/20.jpg)

• The inability of the heart to maintain an output adequate to sustain the metabolic demands of the body
![Page 44: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/44.jpg)
Pulmonary Edema & Acute Pulmonary EDEMA• An abnormal accumulation of fluid in the
lungs
![Page 45: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/45.jpg)
Conditions that mimic CHF
![Page 46: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/46.jpg)
COPD
• Triad of distinct diseases that often coexist: • Chronic Bronchitis • Emphysema• Asthma
![Page 47: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/47.jpg)
Chronic Bronchitis
• Inflamatory changes and excessive mucous production in the bronchial tree
• Commonly caused by prolonged exposure to irritants
![Page 48: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/48.jpg)
The “BLUE BLOATER”
![Page 49: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/49.jpg)
Emphysema
• Characterized by: • Permanent abnormal
enlargement of the air spaces beyond the terminal bronchioles
• Destruction of the alveoli • Failure of the supporting
structures to maintain alveolar integrity
• Results in:• Reduced surface area • Reduced elasticity, leading to air
trapping • Residual volume increases while
vital capacity remains normal
![Page 50: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/50.jpg)
The “PINK PUFFER”
![Page 51: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/51.jpg)
Asthma
• Common chronic disorder of the airways that is complex and characterized by variable and recurring symptoms
• Asthma Triad: • Increased mucous production• Increased bronchial edema• Bronchospasm
![Page 52: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/52.jpg)
Asthma
![Page 53: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/53.jpg)
Pneumonia
• Infection in the lung, specifically the alveoli
![Page 54: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/54.jpg)
CPAP
![Page 55: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/55.jpg)
What EXACTLY IS CPAP?
![Page 56: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/56.jpg)
Where does CPAP FALL
![Page 57: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/57.jpg)
PEEP
• Positive End Expiratory Pressure• the amount of pressure above atmospheric pressure
present in the airway at the end of the respiratory cycle
• Goal of PEEP: • Improve oxygenation
• Amount of PEEP: • 5-10 cm H2O
• Too much PEEP:• >15 cm H2O may force air past the epiglottis
• >20-30 cm H2O can cause a decrease in venous return or LV preload causing hypotnesion.
![Page 58: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/58.jpg)
![Page 59: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/59.jpg)
What we are doing
• In pulmonary edema, fluid accumulates in the alveoli impairing gas exchange.
• CPAP increases the size of the airway and allows gas exchange to occur due to the increased surface area.
• CPAP changes the partial pressure of O2 in the blood
• Deoxygenated blood has a lower partial pressure of O2 in comparison to the air within the alveoli
• Oxygen diffuses from the alveolar air into the blood
![Page 60: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/60.jpg)
![Page 61: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/61.jpg)
What we want to do!
• Put more oxygen into the blood • Improving gas exchange
• Maintain a positive pressure in the lungs• Move some of the fluid out of the lung• Stops fluid from moving into the lungs
• Open the alveoli to preventing collapse
• Increasing the surface area in the alveoli will improve the gas exchange
• Increases intrathoracic pressure• Improves cardiac output to a degree• Too Much PEEP decreases cardiac output
![Page 62: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/62.jpg)
What will we see?
• In a perfect world: • Improved gas exchange• Decreased anxiety • Improved vital signs
• Decreased blood pressure • Decreased pulse rate
• Increased SpO2
• Improved respiratory effort • Decreased respiratory rate
• Decreased need for intubation
![Page 63: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/63.jpg)
• But we don’t live in a perfect world • Some patient’s will be too far gone and CPAP
will not turn the patient around • Some patient’s wont tolerate CPAP• Some patient’s will require intubation
![Page 64: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/64.jpg)
BUT WHAT HAPPENES TO THE FLUID?
![Page 65: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/65.jpg)
• The fluid is not being removed from the body by CPAP
• CPAP does not fix the entire problem
![Page 66: CPAP and EMS](https://reader038.fdocuments.us/reader038/viewer/2022102518/554b6110b4c905793d8b52ae/html5/thumbnails/66.jpg)
