Recognising out-of-hospital cardiac arrest during emergency calls increases bystander cardiopulmonary resuscitation and survival

Abstract

Recognition of OHCA during emergency calls was positively associated with the provision of bystander CPR, ROSC, and 30-day survival in witnessed OHCA.

European Resuscitation Council Guidelines for Resuscitation: 2017 update

“…Recent evidence reinforces the importance of bystander CPR to improve survival from cardiac arrest [17][18][19][20][21]. The ERC recognises the critical role that the EMS dispatcher and dispatch protocols play in supporting bystander initiated CPR [22][23][24][25][26].…”

Survival in Out-of-Hospital Cardiac Arrest After Standard Cardiopulmonary Resuscitation or Chest Compressions Only Before Arrival of Emergency Medical Services

“…77 The proportion of OHCA recognition during alarm calls ranges from 14 % and 83 %. [78][79][80][81][82] The median rate of recognition across dispatch system have been found to be 73 % in a systematic review. 83 Agonal breathing is one of the main barriers for recognition during an alarm call.…”

2019 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations

“…Overall survival at hospital discharge did not differ between these groups, 34 although survival at 1 month favored patients who received bystander DA-CPR. 27,36 Recipients of bystander DA-CPR were also more likely to have ROSC on hospital arrival than when bystander CPR was rendered without dispatch assistance. 27 Although these studies do not prove equivalence or noninferiority, they suggest that DA-CPR could possibly be as effective as spontaneously provided (unassisted) CPR.…”
