Background— A clinical observational study revealed that rescuers consistently hyperventilated
patients during out-of-hospital cardiopulmonary resuscitation (CPR). The objective of …

Background The impedance threshold device (ITD) is designed to enhance venous return
and cardiac output during cardiopulmonary resuscitation (CPR) by increasing the degree of …

Context The health and policy implications of regional variation in incidence and outcome of
out-of-hospital cardiac arrest remain to be determined. Objective To evaluate whether …

Background Among patients with out-of-hospital cardiac arrest (OHCA) and ventricular
fibrillation, more than half present with refractory ventricular fibrillation unresponsive to initial …

Background Active compression-decompression cardiopulmonary resuscitation (CPR) with
decreased intrathoracic pressure in the decompression phase can lead to improved …

Background Discharging patients with acute myocardial infarction or unstable angina from
the emergency department because of missed diagnoses can have dire consequences. We …

Objective: To examine the hypothesis that excessive ventilation rates during performance of
CPR by overzealous but well-trained rescue personnel causes a significant decrease in …

Basic life support (BLS) is the foundation for saving lives following cardiac arrest. Fundamental
aspects of BLS include immediate recognition of sudden cardiac arrest (SCA) and …

The "2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and
Emergency Cardiovascular Care" increased the focus on methods to ensure that high-quality …

Background— Quality cardiopulmonary resuscitation contributes to cardiac arrest survival.
