CPR is probably one of the most ancient procedure (800 BC) recorded in modern history. 2005 CPR guidelines from American Heart Association suggests:
1. 100 compressions per minute.
2. Compression depth of 1 to 2 inches.
3. Allow the chest to recoil completely after each compression (target equal compression and relaxation times)
4. Minimize interruptions in chest compressions. No-flow Fraction* (no-flow fraction of .17)
5. Compression-ventilation ratio of 30:2 (two rescue breaths every 30 chest compressions). Do not deliver more volume or use more force than is needed to produce visible chest rise. Once intubated: ventilate at a rate of 8 to 10 breaths per minute without attempting to synchronize breaths between compressions.
*NFF= No-flow Fraction was defined as the no-flow time (time periods of cardiac arrest without compressions) divided by total cardiac arrest time.
Unfortunately study shows we have not mastered our most ancient procedure yet.3
