Basic Life Support BLS CPR, AED

CPR EMERGENCY MEDICINE:-



Basic Life Support (BLS):
BLS involves emergency methods to assist
someone facing life-threatening situations like
sudden cardiac arrest. Actions include chest
compressions for blood circulation and rescue
breaths for oxygen provision. The goal is to buy
time until professional medical assistance
arrives.


CPR (Cardiopulmonary Resuscitation):
In an emergency:


- Check for responsiveness.

,- Call for help.
- Open the airway and check for breathing.
- Administer chest compressions
(30 compressions, 2 breaths).
- Use an AED if available.
AED (Automated External Defibrillator):
AED is a smart device that analyzes heart
rhythm during CPR. Steps:


- Turn it on.
- Attach electrode pads for rhythm evaluation.
- Stand clear during shock delivery.

, - If suggested, deliver the shock and resume
CPR. AEDs increase survival probabilities during
sudden cardiac arrest.
Shockable Rhythms vs. Non-shockable
Rhythms:
Shockable rhythms (VF and VT) can be
corrected by AED shocks.
Non-shockable rhythms (Asystole, PEA) do not
benefit from AED shocks.


CPR Ratio:


Adult CPR ratio: 30 compressions to 2 rescue
breaths.
Child CPR ratio: 30:2.
Neonatal CPR ratio: 3 compressions to 1 breath.
