Intermittent positive-pressure ventilation, chest compression synchronized ventilation, bilevel ventilation, continuous chest compression, active compression decompression, and impedance threshold device - The complexity of ventilation during cardiopulmonary resuscitation

摘要

As many as 300,000 out-of-hospital cardiac arrests may occur annually in the United States. Despite 50 years of research, survival rate remains low between 3% and 17% (1). To maximize the chances of survival of patients with cardiac arrest, it is necessary for the chain of survival to be as efficient as possible. Chest compression method has not significantly changed since its first description by Kouwenhoven et al (2) in 1960. The two main additions for this mechanical part of the cardiopulmo-nary resuscitation (CPR) are the active compression decompression (ACD) CPR (3) and the mechanical CPR techniques (4). Even taking into account those changes, the basic idea remains the same: push hard and fast on the chest and do not stop.
