dc.description.abstract | Objective: To determine whether dispatcher assistance via smart glasses improves bystander basic life support (BLS) performance compared with standard telephone assistance in a simulated out-of-hospital cardiac arrest (OHCA) scenario. Methods: Pilot study in which 28 lay people randomly assigned to a smart glasses-video assistance (SG-VA) intervention group or a smartphone-audio assistance (SP-AA) control group received dispatcher guidance from a dispatcher to provide BLS in an OHCA simulation. SG-VA rescuers received assistance via a video call with smart glasses (Vuzix, Blade) connected to a wireless network, while SP-AA rescuers received instructions over a smartphone with the speaker function activated. BLS protocol steps, quality of chest compressions, and performance times were compared. Results: Nine of the 14 SG-VA rescuers correctly completed the BLS protocol compared with none of the SP-AA rescuers (p = 0.01). A significantly higher number of SG-VA rescuers successfully opened the airway (13 vs. 5, p = 0.002), checked breathing (13 vs. 8, p = 0.03), correctly positioned the automatic external defibrillator pads (14 vs.6, p = 0.001), and warned bystanders to stay clear before delivering the shock (12 vs. 0, p < 0.001). No significant differences were observed for performance times or chest compression quality. The mean compression rate was 104 compressions per minute in the SG-VA group and 98 compressions per minute in the SP-AA group (p = 0.46); mean depth of compression was 4.5 cm and 4.4 cm (p = 0.49), respectively. Conclusions: Smart glasses could significantly improve dispatcher-assisted bystander performance in an OHCA event. Their potential in real-life situations should be evaluated. | es |
