The association of time to key prehospital interventions recorded by EMT-worn video devices and sustained return of spontaneous circulation in out-of-hospital cardiac arrests

The quality of prehospital resuscitation provided by emergency medical technicians (EMTs) is essential to ensure better outcomes following out-of-hospital cardiac arrests (OHCA). We assessed the quality of prehospital resuscitation by recording time to key prehospital interventions using EMT-worn video devices and investigated its association with outcomes of patients with OHCA.
