Although the importance of bystander cardiopulmonary resuscitation has been shown in multiple studies, the rate of bystander cardiopulmonary resuscitation is still relatively low in many countries. Little is known on bystanders' perceptions influencing the decision to start cardiopulmonary resuscitation. Our study aims to determine such factors. ⋯ The witnessed loss of consciousness was independently associated with a significant reduction in the likelihood that bystander-CPR was started. These data reinforce the importance of teaching the recognition of early cardiac arrest.

Drowning literature have highlighted the submersion time as the most powerful predictor in assessing the prognosis. Reducing the time taken to provide a flotation device and prevent submersion appears of paramount importance. Unmanned aerial vehicles (UAVs) can provide the location of the swimmer and a flotation device. ⋯ UAV can deliver a flotation device to a swimmer safely and quickly. The addition of a UAV in rescue operations could improve the quality and speed of first aid while keeping lifeguards away from dangerous sea conditions.

The association between intra-arrest and post-arrest hyperoxia and mortality in adults with cardiac arrest (CA) is widely debated. We therefore conducted a systematic review and meta-analysis to investigate the association between intra-arrest and post-arrest hyperoxia and mortality in adults with CA. ⋯ In adults with CA, intra-arrest hyperoxia is associated with lower mortality while post-arrest hyperoxia is associated with higher mortality.
