Effect of automated head-thorax elevation during chest compressions on lung ventilation: a model study.

Our goal was to investigate the effects of head-thorax elevation (HUP) during chest compressions (CC) on lung ventilation. A prospective study was performed on seven human cadavers. Chest was automatically compressed-decompressed in flat position and during progressive HUP from 18 to 35°.

Cardiac Arrest Management in the Workplace: Improving but Not Enough?

The aim was to describe out-of-hospital cardiac arrest (OHCA) occurring in the workplace of a large emergency network, and compare the evolution of their management in the last 15 years. A retrospective study based on data from the Northern Alps Emergency Network compared characteristics of OHCA between cases in and out the workplace, and between cases occurring from January 2004 to December 2010 and from January 2011 to December 2017. Among the 15,320 OHCA cases included, 320 occurred in the workplace (2.

Effect of adrenaline dose on neurological outcome in out-of-hospital cardiac arrest: a nationwide propensity score analysis.

Background: Adrenaline is recommended during cardio-pulmonary resuscitation. The optimal dose remains debated, and the effect of lower than recommended dose is unknown.

Objective: To compare the outcome of patients treated with the recommended, lower or higher cumulative doses of adrenaline.

Mildly Reduced Doses of Adrenaline Do Not Affect Key Hemodynamic Parameters during Cardio-Pulmonary Resuscitation in a Pig Model of Cardiac Arrest.

Adrenaline is recommended for cardiac arrest resuscitation, but its effectiveness has been questioned recently. Achieving return of spontaneous circulation (ROSC) is essential and is obtained by increasing coronary perfusion pressure (CPP) after adrenaline injection. A threshold as high as 35 mmHg of CPP may be necessary to obtain ROSC, but increasing doses of adrenaline might be harmful to the brain.

Improving post-cardiac arrest cerebral perfusion pressure by elevating the head and thorax.

Aim: The optimal head and thorax position after return of spontaneous circulation (ROSC) following cardiac arrest (CA) is unknown. This study examined whether head and thorax elevation post-ROSC is beneficial, in a porcine model.

Methods: Protocol A: 40 kg anesthetized pigs were positioned flat, after 7.

Relationship between hemodynamic parameters and cerebral blood flow during cardiopulmonary resuscitation.

Introduction: Cerebral blood flow during cardiopulmonary resuscitation (CPR) is a major neuroprognostic factor although not clinically feasible for routine assessment and monitoring. In this context, a surrogate marker for cerebral perfusion during CPR is highly desirable. Yet, cerebral blood flow hemodynamic determinants remain poorly understood and their significance might be altered by changes in head positioning such as flat, head up, and head down during CPR.
