Question 1

Survival rate out-of-hospital arrest (resuscitation attempted)

Answer 1

9%

Question 2

Survival rate in-hospital cardiac arrest (resuscitation attempted)

Answer 2

23.9%

Question 3

How many arrest rhythms are shockable vs non-shockable during in-hospital and out-of-hospital arrests? How does survival rate vary with shockable vs non-shockable?

Answer 3

In hospital - shockable 18%, non-shockable 73%
Out-of-hospital - shockable 25%, non-shockable 75% (aystole 50%, PEA 25%)

Better survival with shockable

Question 6

Non-shockable rhythms

Answer 6

PEA
Asystole
