Outline IHCA Hospitals Vary in Outcome Why What is recommended How should it be done Does it really matter
Slide 4-

IHCA is pretty common… ˜200,000 in the US Survival is 18-20% There is tremendous variability among hospitals Get with the Guidelines 135,896 20% with Ventricular fibrillation or Ventricular tachycardia 64% occur in an ICU Median Survival Varies 8.3% at the lowest Decile 31.4 at the highest JAHA. 2014;3:e000400

What seems to work? Performing ACLS correctly is associated with an improvement in outcome MUSC study Compared guideline adherence for survivors vs. non-survivors 75 survivors 75 non-survivors Survivors older and with more cormorbidities Resuscitation. 2013;85:82-87

Chest Compressions Place patient on a firm surface Backboard Deflation of air mattress Had in the middle of the chest 5 cm of depression Allow complete recoil Lifting the hand completely of the chest can improve recoil Circulation. 2010;122:S685-705
Slide 21-

How Fast Rate 100-120 cpm Deliver >80 per minute That means minimal interruption Duty Cycle Time between the start of one compression and the start of the next Target is 50% As much time relaxing as compressing Circulation. 2010;122:S685-705

Survival from OHCA improved after the implementation of a protocol that required 90 seconds of CPR prior to the delivery of a shock via an AED 24% to 30% Particularly in those in whom the intial response interval was > 4 min. JAMA. 1999;281:1182-1188

Conclusions Chest Compressions are the cornerstone of resuscitation Rate Depth Recoil Minimizing Interruptions Feedback is probably helpful In some cases chest compressions aid defibrillation Mechanical chest compressors have not been demonstrated to be helpful
