• Basic life support (BLS) includes:
1. airway,
2. breathing
3. circulation
4. automated external defibrillator (AED)
5. management of choking or foreign body
airway obstruction (FBAO).

SUDDEN CARDIAC ARREST
31/12/2018

• Sudden cardiac arrest (SCA) is a condition in
which the heart suddenly and unexpectedly
stops beating.
• If this happens, blood stops flowing to the brain
and other vital organs.
• SCA causes death if it's not treated within
minutes.
• In adults, the most common cause is cardiac in
origin.

• Signs and symptoms of cardiac arrest:
1. Unresponsiveness
2. No breathing
3. Abnormal breathing/ agonal breathing
4. Seizure

The main components of the heart
are :
1.Heart muscles - contract to pump
blood
2.Heart chambers - collect and
channel blood flow
3.Heart valves - allows only one way
flow of blood
4.Conduction system - coordinate
heart muscle contraction
5.Coronary blood vessels - supply
blood to the heart
ANATOMY & PHYSIOLOGY OF CVS
1. The heart is a muscular organ which pumps a continuous flow of blood
through the blood vessels of the circulatory system.
2. The cardiovascular system maintains blood flow to deliver oxygen and
nutrients to every cell and removes the carbon dioxide and waste products
made by those cells.

• Effective external chest compressions pushes
blood out of heart chambers thus maintain
blood flow and oxygen delivery to vital organs.
• The recommended maximum rate of chest
compression is 120/min and full chest recoil is
important to allow for adequate perfusion to
the heart muscles and blood filling of the heart
chambers during the relaxation (diastole)
phase.

ANATOMY OF RESPIRATORY
SYSTEM
• The tongue may occlude the upper airway
in an unconscious patient. Thus, opening
the airway is essential.
31/12/2018
10

ANATOMY OF RESPIRATORY
SYSTEM
• However, due to anatomical differences between an adult, children and
neonate airway, head-tilt- chin lift maneuver may differ slightly.
31/12/2018
11

Room air -21% oxygen. Rescue breathing -16% oxygen
PHYSIOLOGY OF RESPIRATORY
SYSTEM
• During cardiac arrest, the body’s metabolic demand for oxygen is decreased.
Therefore a smaller amount of air is needed. When giving ventilation, a visible
chest rise indicates adequate volume of air has been given.
The harm of over or hyperventilation:
• decrease in atrial & ventricular filling
• reduction in coronary perfusion pressure
• distension of the stomach leading to regurgitation & aspiration

Techniques for :
1. Mouth to mouth
2. Mouth to mask
3. Bag-Valve-Mask (single person vs 2 persons)

C : HIGH QUALITY CPR
The rule of 5 :
1. Location : middle of chest , lower ½ of sternum
2. Depth 5-6 cm
3. Rate : 100-120/min
4. Minimize interruption
5. Allow full chest recoil

DEFIBRILLATION

1. Switch on the AED
2. Attach the electrode pads on the victim’s bare chest
 If more than one HCW is present,CPR should be continued while electrode
pads attached to the chest
 Follow the spoken/visual directions
3. Ensure that nobody is touching the victim while the AED is analysing the
rhythm.
4a . If a shock is advised, deliver shock within 5 seconds
5. Ensure that nobody is touching the victim with clear CHANT “I am clear, you
are clear, everyone is clear…”
6. Push shock button as directed (fully automatic AEDs will deliver the
shock automatically)
7. Immediately restart CPR at the compressions:ventilation ratio of
30:2
8. Continue as directed by the voice/visual prompts

RECOGNITION OF CHOKING
36
 History of eating or drinking
 People at higher risk of choking –
i. reduced conciousness
ii. intoxication (alcohol / drug)
iii. neurological impairment (stroke /Parkinson)
iv. older age
v . poor dentition

The victim will
clutch the neck
with the thumb
& fingers and
attempt to
cough
out the foreign
body

UNCONCIOUS CHOKING
42
 As you open the airway to give ventilations, look in the person’s mouth
for any visible object. If you can see it, use a finger sweep motion to
remove it. If you don’t see the object, do not perform a blind finger
sweep, but continue CPR.
 Remember to never try more than 2 ventilations during one cycle of
CPR, even if the chest does not rise.
