Cardiac arrest leaves witnesses, survivors, and their relatives with a multitude of questions. When a young or a public figure is affected, interest around cardiac arrest and cardiopulmonary resuscitation (CPR) increases. ChatGPT allows everyone to obtain human-like responses on any topic. Due to the risks of accessing incorrect information, we assessed ChatGPT accuracy in answering laypeople questions about cardiac arrest and CPR. ⋯ ChatGPT provided largely accurate, relevant, and comprehensive answers to questions about cardiac arrest commonly asked by survivors, their relatives, and lay rescuers, except CPR-related answers that received the lowest scores. Large language model will play a significant role in the future and healthcare-related content generated should be monitored.

Observational Study
The vocal cords are predominantly closed in preterm infants <30 weeks gestation during transition after birth; an observational study.
Studies in animals have shown that vocal cords (VCs) close during apnoea before and after birth, thereby impairing the effect of non-invasive ventilation. We tested the feasibility of visualising VCs using ultrasonography (US) and investigated the position and movement of the VCs during non-invasive respiratory support of preterm infants at birth. ⋯ Visualising VCs in preterm infants at birth using US is feasible. The VCs were closed during apnoea, in between breaths and during breath holds, impairing the effect of ventilation given.

To determine if controlled head and thorax elevation, active compression-decompression cardiopulmonary resuscitation (CPR), and an impedance threshold device combined, termed automated head-up positioning CPR (AHUP-CPR), should be initiated early, as a basic (BLS) intervention, or later, as an advanced (ALS) intervention, in a severe porcine model of cardiac arrest. ⋯ When delivered early rather than late, AHUP-CPR resulted in significantly increased hemodynamics, 24-hour survival, and improved neurological function in pigs after prolonged cardiac arrest. Based on these findings, AHUP-CPR should be considered a BLS intervention.

While telephone-assisted cardiopulmonary resuscitation (T-CPR) is crucial for improving the chances of survival during cardiac arrest, there is limited information available on the effectiveness of T-CPR when administered by laypeople, especially those who are unfamiliar with these procedures. Therefore, we assessed the influence of basic life support and defibrillation (BLSD) training on the proficiency of T-CPR carried out by volunteer medical students participating in a BLSD course, using a simulated cardiac arrest scenario. The quality of T-CPR maneuvers was compared before and after the BLSD course. The results highlight the positive impact of BLSD training, significantly enhancing the quality of T-CPR and bringing it close to optimal levels.
