INTRODUCTION
Fundamental aspects of Basic Life Support(BLS) include immediate recognition ofsudden cardiac arrest (SCA) and activation ofthe emergency response system (EMS),early cardiopulmonary resuscitation ( CPR ),and rapid defibrillation with an automated
external defibrillator ( AED) . Dr. Peter Safar is considered as the father of
modern day CPR

DEFINITION Basic life support is an emergency
procedure that consists of recognising anarrest and initiating propercardiopulmonary resuscitation techniques
to maintain life without the use of drugsor specialist equipment until the victimeither recovers or is transported to a
medical facility where advance lifesupport measures are available.

EMERGENCY ACTION
PRINCIPLE In each emergency, we need to follow the
emergency action principle so that we donot forget anything that might affectpersonal safety (yours and the victims) andthe victims survival.
7/27/2019 Basic Life Support_part-2
6/165
Always follow the steps in order given
below.
1-survey the scene (to confirm the area is
safe for you as well as the victim), 2-do a primary survey of the victim,
3-activates the Emergency Medical Service(EMS) system for help,
4-do a secondary survey of the victim.

ENSURE SAFETY
Survey the scene and make sure thatthe area is safe for the victim as well asto the rescuer.
7/27/2019 Basic Life Support_part-2
10/165
If a lone rescuer finds an unresponsive adult
(i.e., no movement or response to
stimulation) or witnesses an adult
who collapses,
after ensuring that the scene is safe and
positioning the victim in supine on a firm
surface,
7/27/2019 Basic Life Support_part-2
11/165
Immediate Recognition and Activation of
the Emergency Response System The rescuer should check for a response
by tapping the victim on the shoulder and
shouting at the victim, Are you all right? If
the victim is responsive, he or she will
answer, move, or moan.
7/27/2019 Basic Life Support_part-2
12/165
The rescuer should also check for no breathingor no normal breathing (i.e., only gasping )
while checking for responsiveness. if the healthcare provider finds the victim isunresponsive with no breathing or no normalbreathing (i.e., only gasping), the rescuer should
assume the victim is in cardiac arrest. And then, the rescuer should shout for help to
activate the Emergency Response System(EMS) and to get an AED if available.
7/27/2019 Basic Life Support_part-2
13/165
The victim has occasional gasps, which canoccur in the first minutes after SuddenCardiac Arrest (SCA) and may beconfused with adequate breathing.
Occasional gasps do not necessarily resultin adequate ventilation.
The rescuer should treat the victim who has
occasional gasps as if he or she is notbreathing.
7/27/2019 Basic Life Support_part-2
14/165
PULSE CHECK
The healthcare provider should take not morethan 10 seconds to check for a pulse; and if therescuer does not definitely feel a pulse withinthat time, the rescuer should start chestcompressions.The carotid pulse can check while keeping thevictims head tilted back with one hand on the
forehead, use the other hand to find the pulse. First, place your index or middle finger on the
Adams apple.
7/27/2019 Basic Life Support_part-2
15/165
7/27/2019 Basic Life Support_part-2
16/165
Then slide your finger toward in to the
groove between the windpipe and the
muscles at the side of the neck. This is
where the carotid pulse is located.

CHEST COMPRESSIONS
Chest compressions consist of forceful
rhythmic applications of pressure over the
lower half of the sternum.
These compressions create blood flow by
increasing intrathoracic pressure anddirectly compressing the heart.
7/27/2019 Basic Life Support_part-2
25/165
This generates blood flow andoxygen delivery to the vital organs
7/27/2019 Basic Life Support_part-2
26/165
The rescuer should place the heel of thedominant hand on the centre (middle) of thevictim's chest (which is the lower half ofthe sternum ) and the heel of the other hand ontop of the first so that the hands are overlappedand parallel
Position yourself vertically above the victim'schest and, with your arms straight, the adultsternum should be depressed at least 2 inches (5cm) with chest compression and chest
recoil/relaxation times approximately equal. Allow the chest to completely recoil after each
compression.
7/27/2019 Basic Life Support_part-2
27/165
7/27/2019 Basic Life Support_part-2
28/165
To provide effective chest compressions,
push hard and push fast. healthcare providers should compress the
adult chest at a rate of at least 100
compressions per minute with a compression
depth of at least 2 inches/5 cm.
7/27/2019 Basic Life Support_part-2
29/165
Rescuers should allow complete recoil ofthe chest after each compression, toallow the heart to fill completely before thenext compression.
7/27/2019 Basic Life Support_part-2
30/165
7/27/2019 Basic Life Support_part-2
31/165
A compression-ventilation ratio of 30:2 isrecommended.To maximize the effectiveness of chestcompressions, place the victim on a firmsurface when possible, in a supineposition with the rescuer kneeling besidethe victim's chest.Rescuers should attempt to minimize the
frequency and duration of interruptions incompressions to maximize the number ofcompressions delivered per minute.

Incomplete recoil during BLS, CPR is
associated with higher intrathoracic
pressures and significantly decreased
hemodynamics, including decreased
coronary perfusion, cardiac index,
myocardial blood flow, and cerebral
perfusion.

AIR WAY
7/27/2019 Basic Life Support_part-2
45/165
OPEN THE AIRWAY:
The common cause of airway obstructionis back of the tongue blocking the air way.
A healthcare provider should use the headtilt chin lift maneuver to open the airway ofa victim with no evidence of head or necktrauma.
If healthcare providers suspect a cervicalspine injury, they should open the airwayusing a jaw thrust without head extension.

Because maintaining a patent airwayand providing adequate ventilation arepriorities in CPR, use the head tilt chin liftmaneuver if the jaw thrust does notadequately open the airway.
7/27/2019 Basic Life Support_part-2
50/165
Jaw thrust
The practitioner uses their thumbs tophysically push the posterior (back)
aspects of the mandible upwards Whenthe mandible is displaced forward, itpulls the tongue forward and prevents it
from occluding (blocking) the entranceto the trachea, helping to ensure apatent (secure) airway.

RESCUE BREATHING
During CPR, the primary purpose ofassisted ventilation is to maintain
adequate oxygenation; the secondary purpose is to
eliminate CO2.
7/27/2019 Basic Life Support_part-2
58/165
1) MOUTH-TO-MOUTHRESCUE BREATHING
Mouth-to-mouth rescue breathing providesoxygen and ventilation to the victim.To provide mouth-to-mouth rescuebreaths, open the victim's airway, pinch thevictim's nose, and create an airtight mouth-to-mouth seal.Give 1 breath over 1 second. take a "regular" (not a deep) breathe , andgive rescue breath over 1 second.
7/27/2019 Basic Life Support_part-2
59/165
7/27/2019 Basic Life Support_part-2
60/165
Taking a regular rather than a deepbreath prevents the rescuer from gettingdizzy or lightheaded and prevents overinflation of the victim's lungs.
The most common cause of ventilationdifficulty is an improperly openedairway, so if the victim's chest does notrise with the first rescue breath.
Reposition the head by performingthe head tilt chin lift again and then givethe second rescue breath.
7/27/2019 Basic Life Support_part-2
61/165
7/27/2019 Basic Life Support_part-2
62/165
If an adult victim with spontaneouscirculation (ie, strong and easily
palpable pulses) requires support ofventilation, the healthcare providershould give rescue breaths at a rate ofabout 1 breath every 5 to 6 seconds, orabout 10 to 12 breaths per minute.
Each breath should be given over 1second regardless of whether anadvanced airway is in place.
Each breath should cause visible chestrise.
7/27/2019 Basic Life Support_part-2
63/165
Use a compression to ventilation ratio of30 chest compressions to 2 ventilations

7/27/2019 Basic Life Support_part-2
66/165
More important, excessive ventilation canbe harmful because it increasesintrathoracic pressure, decreases venousreturn to the heart, and diminishescardiac output and survival.
2) MOUTH TO BARRIER
7/27/2019 Basic Life Support_part-2
67/165
2) MOUTH-TO BARRIERDEVICE BREATHING.
Some healthcare providers mayhesitate to give mouth-to-mouth rescuebreathing and prefer to use a barrier
device. The risk of disease
transmission through mouth-to-barrier
ventilation is very low. When using a barrier device the rescuer
should not delay chest compressions
while setting up the device.

VENTILATION Mouth-to-nose ventilation is recommendedif ventilation through the victim's mouth isimpossible (eg, the mouth isseriously injured), the mouth cannot beopened, the victim is in water, or a mouth-to-mouth seal is difficult to achieve.
A case series suggests that mouth-to-noseventilation in adults is feasible, safe, andeffective

AED, DEFIBRILLATION
An Automated External Defibrillator (AED)is used when the heart stops beatingnormally and needs to be reset by anelectric shock.
AEDs are designed for adults but most canbe adapted for children with paediatricpads down to 1 year of age.
Provide 5 cycles of CPR, 30 compressionsto 2 breaths, for 2 minutes before using an
AED on a child from 1 year to puberty

SEQUENCE OF ACTIONS WHENUSING AN AUTOMATED EXTERNAL
DEFIBRILLATOR The following sequence applies to the
use of both semi-automatic andautomatic AEDs in a victim who is foundto be unconscious and not breathingnormally.
1. Follow the adult BLS sequence asdescribed. Do not delay starting CPRunless the AED is available
Immediately.
7/27/2019 Basic Life Support_part-2
76/165
2. AS SOON AS THE AED
ARRIVES: If more than one rescuer is present, continueCPR while the AED is switched on.
If you are alone, stop CPR and switch on the
AED. Follow the voice / visual prompts. Attach the
electrode pads to the patients bare chest.
Ensure that nobody touches the victim while the AED is analysing the rhythm.

OBSTRUCTION (FBAO)
(CHOKING) The rescuer should intervene if thechoking victim shows signs of severeairway obstruction.
These include signs of poor air exchangeand increased breathing difficulty, such asa silent cough, cyanosis, or inability to
speak or breathe. The victim may clutch the neck,
demonstrating the universal choking sign.
7/27/2019 Basic Life Support_part-2
88/165
7/27/2019 Basic Life Support_part-2
89/165
Quickly ask, "Are you choking?" If the
victim indicates "yes" by nodding his head
without speaking, this will verify that the
victim has severe airway obstruction.

Chest thrusts should be used for obese
patients if the rescuer is unable to encircle
the victim's abdomen.
If the choking victim is in the late stages of

ABDOMINAL THRUSTS FOR
AN UNCONSCIOUS VICTIM If the adult victim with Foreign-Body AirwayObstruction becomes unresponsive, therescuer should carefully support the patient to
the ground. Immediately activate (or send someone to
activate) EMS, and then begin CPR. The healthcare provider should carefully lower
the victim to the ground, send someone toactivate the emergency response system andbegin CPR (without a pulse check).
After 2 minutes, if someone has not
7/27/2019 Basic Life Support_part-2

If the victim is unresponsive and notbreathing (or only gasping), begin CPR.
Sometimes victims who require CPR willgasp, which may be misinterpreted asbreathing.
Treat the victim with gasps as thoughthere is no breathing and begin CPR.

For an unresponsive child who is notbreathing or not breathing normally, beginCPR with 30 compressions followed by
opening the airway and giving 2 rescuebreaths. Repeat cycles of 30:2 (CAB method).
For an infant, lone rescuers (whether lay
7/27/2019 Basic Life Support_part-2

rescuers or healthcare providers) should
compress the sternum with 2 finger placed
just below the intermammary line.
Do not compress over the xiphoid or ribs.
Rescuers should compress at least one-
third the depth of the chest, or about 4 cm
(1.5 inches).
Do not press on the xiphoid or the ribs.

Push hard : push with sufficient force to
depress at least one third the
anterior posterior (AP) diameter of the
chest or approximately 1 inches (4 cm)

OPEN THE AIRWAY AND GIVEVENTILATIONS For the lone rescuer a compression-to-
7/27/2019 Basic Life Support_part-2
145/165
ventilation ratio of 30:2 is recommended.
After the initial set of 30 compressions, open
the airway and give 2 breaths.
In an unresponsive infant or child, the tongue
may obstruct the airway and interfere with
ventilations.

Open the airway using a head tilt chin lift
maneuver for both injured and non-injured
victims.
To give breaths to an infant, use a mouth-
to-mouth-and-nose technique; to give
breaths to a child, use a mouth-to-mouthtechnique.
Make sure the breaths are effective (ie,
the chest rises)
7/27/2019 Basic Life Support_part-2

the chest rises).
Each breath should take about 1 second.
If the chest does not rise, reposition the
head, make a better seal, and try again.
It may be necessary to move the child's
head through a range of positions toprovide optimal airway patency and
effective rescue breathing

In an infant, if you have difficulty making
7/27/2019 Basic Life Support_part-2
150/165
an effective seal over the mouth and nose,
try either mouth-to-mouth or mouth-to-
nose ventilation.
If you use the mouth-to-mouth technique,
pinch the nose closed.
If you use the mouth-to-nose technique,
close the mouth.
7/27/2019 Basic Life Support_part-2

In either case make sure the chest rises
7/27/2019 Basic Life Support_part-2
152/165
when you give a breath.
If you are the only rescuer, provide 2
effective ventilations using as short a
pause in chest compressions as possible
after each set of 30 compressions.

DEFIBRILLATION
7/27/2019 Basic Life Support_part-2
156/165
Ventricular fibrillation (VF) can be thecause of sudden collapse or maydevelop during resuscitation attempts.
Children with sudden witnessedcollapse (eg, a child collapsing duringan athletic event) are likely to have VF
or pulseless ventricular tachycardia (VT)and need immediate CPR and rapiddefibrillation.
VF and pulseless VT are referred to as"shockable rhythms" because they
7/27/2019 Basic Life Support_part-2
157/165
y yrespond to electric shocks (defibrillation).
Many AEDs have high specificity inrecognizing paediatric shockable rhythms,and some are equipped to decrease (orattenuate) the delivered energy to makethem suitable for infants and children
7/27/2019 Basic Life Support_part-2
158/165
defibrillation is 2 J/kg. If a second dose is
required, it should be doubled to 4 J/kg.
If a manual defibrillator is not available, an
AED equipped with a paediatric attenuator
is preferred for infants.
An AED with a paediatric attenuator is also
preferred for children
7/27/2019 Basic Life Support_part-2
159/165
dose attenuator may be used.
AEDs that deliver relatively high-energy
doses have been successfully used in
infants with minimal myocardial damage
and good neurological outcomes.
