Study Notes

Cardiopulmonary Resuscitation (CPR) Overview

CPR is an emergency procedure used to manually preserve brain function during cardiac arrest.
Its main purpose is to restore partial oxygenated blood flow to the brain and heart, thereby delaying tissue death and increasing the survival chance without permanent brain damage.
CPR alone is unlikely to restart the heart.

CPR Steps

Check response and scan for breathing: Assess responsiveness and breathing.
Check pulse: Feel for a pulse for 5-10 seconds. If no pulse is found, begin CPR.
Activate emergency response system (ERS) and get AED: If possible, ask another rescuer to activate the ERS and get an AED (Automated External Defibrillator).
If alone: Prefer calling ERS and getting an AED rather than treating the victim.

CPR Techniques

Start Chest Compressions:
- Position yourself at the victim's side.
- Ensure the victim is lying face-up on a firm, flat surface.
- Place the heel of one hand on the center of the victim's chest, on the lower half of the sternum.
- Straighten your arms and position your shoulders directly over your hands.
- Perform 30 compressions and 2 breaths repeatedly in cycles. Aim for high-quality CPR.
Opening the Airway:
- Employ the Head Tilt-Chin Lift (if no head or neck injury suspected) or Jaw Thrust methods.
- Place one hand on the victim's forehead and push with your palm to tilt the head back. Place the other hand under the bony part of the lower jaw to lift.
- Lift the jaw to bring the chin forward, relieving airway obstruction.
Giving Breaths:
- Employ Mouth-to-Mouth, Mouth-to-Mask, or Bag-and-Mask breathing techniques.

High-Quality CPR

Start within 10 seconds of recognizing arrest.
Compressions should be performed at a rate of at least 100 per minute.
Compressions should be forceful enough to compress the chest at least 5 centimeters in adults, 5 cm in children, and 4 cm in infants.
Allow for complete chest recoil between compressions.
Minimize interruptions during CPR.

AED Use

Turn on the AED.
Attach pads to the victim's bare chest.
Connect the cables.
Analyze the rhythm.
Deliver a shock if advised by the AED.
Resume CPR immediately following a shock.

CPR for Specific Populations

Children (one-handed chest compressions)
Infants (modified chest compressions)

Special Situations

Water
Transdermal drugs
