Cardiac arrest & resuscitation
Time to bystander cardiopulmonary resuscitation by patient sex for out-of-hospital cardiac arrest
Authors' conclusion
For patients with witnessed OHCA that received bystander CPR, women and men had similar times to CPR, although 5-minute or greater delays in initiating CPR was not uncommon. Delays in bystander CPR in OHCA were associated with worse survival outcomes.
