From: How senior paramedics decide to cease resuscitation in pulseless electrical activity out of hospital cardiac arrest: a mixed methods study

System factors N (%) Duration hr:min:sec
No flow time& median (IQR) 50 (100) 0:07:30 (4.46–15.25)
Duration of BLS median (IQR) 26 (52) 0:07:35 (4.58–16.01)
Duration of lone ambulance BLS median (IQR) 23 (46) 0:07:32 (5.31–15.9)
Duration of ALS# mean (SD) 50 (100) 0:54:46 (0:16:59)
Duration of resuscitation^ (BLS & ALS) mean (SD) 50 (100) 0:59:32 (0:17:39)
Total duration of out of hospital cardiac arrest mean (SD) 50 (100) 1:09:23 (0:19:53)
  1. &No flow time, time from collapse to the start of resuscitation
  2. Lone ambulance responders (community responders, advanced technicians, paramedics, duty officers) providing BLS only
  3. #ALS time of ambulance arrival to confirmation of death
  4. ^Duration of out of hospital cardiac arrest, no flow time to confirmation of death
