Brief Summary

Out-of-hospital cardiac arrest (OHCA) remains a major cause of death globally, with bystander CPR rates varying widely (13-82%) despite public health efforts. Early recognition, EMS activation, and immediate CPR are key to survival, often beginning with a layperson guided by an emergency dispatcher. Telephone-assisted CPR (T-CPR), where dispatchers give verbal instructions, is common but limited-dispatchers can't see the scene or correct CPR technique. In contrast, video-assisted CPR (V-CPR) enables visual feedback, potentially improving performance in areas like compression rate and hand placement. However, evidence is mixed regarding its effect on compression depth, and initiating a video call may introduce delays. While V-CPR's technical benefits have been studied, little is known about how real-world distractions-like noise or poor lighting-affect its effectiveness. Our simulation study aimed to compare T-CPR and V-CPR under both ideal and challenging conditions to assess the impact of environmental factors on layperson CPR quality and dispatcher support.

Interventions

sV-CPR BEHAVIORAL

In the sV-CPR group, participants manage a simulated cardiac arrest scenario alone. They perform CPR while establishing a video connection with a dispatcher located in another room using a smartphone. To simulate challenging conditions, they must carry out the task in near-total darkness, with the phone's flashlight as the only light source.

V-CPR

T-CPR BEHAVIORAL

In the T-CPR group, participants manage a simulated cardiac arrest scenario alone. They perform CPR while establishing a telephone connection with a dispatcher located in another room using a smartphone (vocal communication only).

T-CPR

sT-CPR BEHAVIORAL

In the sT-CPR group, participants manage a simulated cardiac arrest scenario alone. They perform CPR while establishing a telephone connection with a dispatcher located in another room using a smartphone (vocal communication only). To simulate challenging conditions, they must carry out the task in higher environmental noises (traffic), generated by a loudspeaker.
