Q

Adult chain of survival

A
  1. Immediate recognition of cardiac arrest and activation of emerygency response system
  2. Early CPR with good chest compressions
  3. Rapid defibrillation
  4. Effective advanced life support

Q

Mechanism of action of cardiac pump in chest compressions

A

Blood pumping is assured by compression of heart between sternum and spine
Between compressions, thoracic cage expands and heart gets filled with blood

Q

Mechanism of action of thoracic pump in chest compressions

A

During chest compresion, increased pressure in the chest caused forward movement of blood through the circulatory system

Q

Process of rescue breathing

A

Adults- 1breath/5-6 sec (10-12min)
Children/infants- 1 breath 3-5secs (12-20min)

Give each breadth within 1 minute
Observe visible chest rise with each breadth

check pulse every 2 min
