in Hospital Cardiac Arrest

The goal of this prospective observational study is to learn how ventilation quality parameters during cardiopulmonary resuscitation (CPR) are associated with short-term survival following in-hospital cardiac arrest of adult patients. The main questions it aims to answer are: What ventilation volume during CPR is associated with the highest chance of return of spontaneous circulation (ROSC)? What ventilation rate during CPR is associated with the highest chance of ROSC? Researchers will compare different levels of ventilation rates and volumes that are blindly measured during CPR to see how the observed rates and volumes are associated with survival outcomes and complications.

High-quality chest compressions are critical for outcomes after pediatric cardiac arrest, yet rescuer ergonomics and bed height may adversely affect compression quality and fatigue. This randomized crossover simulation study will evaluate how four different bed-height settings influence pediatric CPR quality and rescuer biomechanics. Pediatric emergency medicine residents will perform 2-minute chest-compression-only CPR on a pediatric manikin placed on a hospital bed under four bed-height conditions in randomized order across separate sessions. CPR quality metrics from the manikin's feedback system, rescuer fatigue, physiologic responses, and arm angle over time will be compared to identify an ergonomically optimal bed-height approach.

: An intrahospital CA data recording protocol has been designed following the Utstein model. Database is hosted according to European legislation regarding patient data protection. It is drafted in English and Spanish. Invitation to participate has been sent to Spanish, European and Latinamerican hospitals. Variables included, asses hospital characteristics, the resuscitation team, patient's demographics and background, CPR, post-resuscitation care, mortality, survival and long-term evolution. Survival at hospital discharge will be evaluated as a primary outcome and survival with good neurological status as a secondary outcome, analyzing the different factors involved in them
