Bystander cardiopulmonary resuscitation in out-of-hospital cardiac arrest is associated with higher survival rates.
Even trained health care staff cannot assess breathing well enough to detect cardiac arrest. Recognition of cardiac arrest by lay rescuers might be overlooked in adult basic life support resuscitation guidelines, which explain what to do, but not how to do it.
Monocentric, blinded, prospective, 2-arm parallel randomized controlled trial with balanced randomization The design entailed a preallocation simulation, an intervention video debriefing with or without gaze overlay , and a postallocation simulation.
A follow-up simulation took place after 6 months. The main outcome measured was success in detecting breathing. Participants were all prospective students of a bachelor's degree program in nursing. We failed to obtain a sufficient number of participants for the follow-up simulation. Instructing lay rescuers to look for chest movement allows them to detect breathing or lack thereof.
Mean thorax gaze duration significantly increased by 5. Laypersons' median diagnosis time was This is the second study in which the median time to decision exceeded the maximum 10 seconds recommended. Bystander cardiopulmonary resuscitation CPR in out-of-hospital cardiac arrest is associated with higher survival rates and improved outcomes, such as diminished anoxic brain damage, nursing home admission, and risk of death at 1 year.
