Although brain injury is the main determinant of poor outcome following cardiac arrest (CA), cardiovascular failure is the leading cause of death within the first days after CA. However, it remains unclear which hemodynamic parameter is most suitable for its early recognition. We investigated the association of cardiac power output (CPO) with early mortality in intensive care unit (ICU) after CA and with mortality related to post-CA cardiovascular failure. ⋯ In post-CA patients, the 8-hour CPO is an independent factor associated with ICU cardiovascular-related mortality.

Observational Study
Empowering the Next Generation: An innovative "Kids Save Lives" blended learning programme for schoolchildren training.
Guidelines recommend teaching resuscitation from school age; however, little is known about the best methods to provide it. We devised a blended learning program for primary and secondary students (Kids Save Lives - KSL) consisting of brief lectures, practical training with mannequins, and virtual reality. We aimed to evaluate its impact on students' attitudes towards intervening during cardiac arrest and their knowledge about basic life support. ⋯ The blended learning method improved students' understanding of basic life support techniques and their attitude to act during cardiac arrest situations. The positive reception of the virtual reality component underscores technology's potential to bolster engagement and should be further explored for basic life support teaching in schoolchildren.

We sought to describe the impact of the COVID-19 pandemic on the care provided by Canadian emergency medical system (EMS) clinicians to patients suffering out of hospital cardiac arrest (OHCA), and whether any observed changes persisted beyond the initial phase of the pandemic. ⋯ The COVID-19 pandemic was associated with substantial changes in EMS management of OHCA. EMS leaders should consider these findings to optimise current OHCA management and prepare for future pandemics.

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.
