“…The speaker function on phones could be a solution to this communication challenge with information passing through the caller to bystanders closer to the victim, 9 although people who lack the technical skills may find this solution difficult. 26 Some of these technical difficulties may be of less concern in the future.…”

“…These efforts have focused on how best to educate laypersons and to use dispatcher-assisted telephone-guided cardiopulmonary resuscitation (T-CPR) to assist them perform CPR during the emergency call. [5][6][7][8][9][10] Bystanders' interactions with Emergency Medical Dispatchers (dispatcher) during the emergency calls can improve the rate of recognition of cardiac arrest and of bystanders' CPR. 5,[11][12][13] In addition, the dispatcher can refer the caller to the nearest Automated External Defibrillator (AED).…”

Challenges in out-of-hospital cardiac arrest – A study combining closed-circuit television (CCTV) and medical emergency calls

CCTV combined with audio recordings from emergency calls can provide unique insights into the challenges of recognition and initial treatment of OHCA and can improve understanding of the situation. The main barriers to effective intervention were situation awareness, communication and attitude/approach. Potentially, some of these challenges could be minimized if the dispatcher was able to see the victim and the bystanders at the scene. A team approach, with the dispatcher responsible for the role as team leader of a remote resuscitation team of a caller and bystanders, may potentially improve treatment of OHCA.

“…Birkenes et al . observed that lay people understood the center of the chest to be the same as the center of the torso20 and nearly half of their study participants who learned CPR even 6–9 months ago placed their hands too low 21. Guidelines claim that CPR by lay rescuers is quite safe even for victims who are not in CA 23, 24.…”

“…As our study showed, giving instructions of the actual depth of 5 cm or to push hard may not be appropriate to achieve the optimal depth of chest compressions by lay rescuers. Since they tend to perform shallow chest compressions from the very beginning, dispatchers may need to keep encouraging rescuers to perform “harder, harder, and much harder” compressions 21, 26. Future studies on modifying the existing protocol including this coaching process will give us more information on improving the quality of DACPR.…”

AimBystander cardiopulmonary resuscitation (CPR) is essential for improving the outcomes of sudden cardiac arrest patients. It has been reported that dispatch‐assisted CPR (DACPR) accounts for more than half of the incidence of CPR undertaken by bystanders. Its quality, however, can be suboptimal. We aimed to measure the quality of DACPR using a simulation study.MethodsWe recruited laypersons at a shopping mall and measured the quality of CPR carried out in our simulation. Dispatchers provided instruction in accordance with the standard DACPR protocol in Japan.ResultsTwenty‐three laypersons (13 with CPR training experience within the past 2 years and 10 with no training experience) participated in this study. The median chest compression rate and depth were 106/min and 33 mm, respectively. The median time interval from placing the 119 call to the start of chest compressions was 119 s. No significant difference was found between the groups with and without training experience. However, subjects with training experience more frequently placed their hands correctly on the manikin (84.6% versus 40.0%; P = 0.026). Twelve participants (52.2%, seven in trained and five in untrained group) interrupted chest compressions for 3–18 s, because dispatchers asked if the patient started breathing or moving.ConclusionThis current simulation study showed that the quality of DACPR carried out by lay rescuers can be less than optimal in terms of depth, hand placement, and minimization of pauses. Further studies are required to explore better DACPR instruction methods to help lay rescuers perform CPR with optimal quality.

The results demonstrate that the local T-CPR concept for untrained laypersons is feasible in a mock scenario. No substantial errors were observed for the majority of the untrained responders but the simulation also showed that not every emergency witness implemented the instructions according to the dispatcher's expectations. The T-CPR procedure was also more time-consuming than expected; therefore, every standardized T-CPR concept should be tested for local practicability. In accordance with current studies, the results suggest that the focus should be on compression-only CPR instructions in urban settings. Dispatcher education in T-CPR should incorporate videotaped mock-up scenarios with untrained local laypersons.
