Objective: Previous research has suggested that the physical demands of performing cardiopulmonary resuscitation (CPR) are relatively low. However, the subjects studied have generally been of a young age. The aim of this study was to test the hypothesis, in null form, that the physiological responses to the performance of single operator CPR for 10 min are independent of age. Read More

Objective: Optimal chest compression to ventilation ratio (C:V) for one-rescuer cardiopulmonary resuscitation (CPR) is not known, with current American Heart Association recommendations 3:1 for newborns, 5:1 for children, and 15:2 for adults. C:V ratios influence effectiveness of CPR, but memorizing different ratios is educationally cumbersome. We hypothesized that a 10:2 ratio might provide adequate universal application for all age arrest victims. Read More

Background: Complete chest wall recoil improves hemodynamics during CPR by generating relatively negative intrathoracic pressure, which draws venous blood back to the heart, providing cardiac preload prior to the next chest compression.
Objective: This study was designed to assess the quality of CPR delivered by trained laypersons and to determine if a change in CPR technique or hand position would improve complete chest wall recoil, while maintaining adequate duty cycle, compression depth, and proper hand position placement. Standard manual CPR and three alternative manual CPR approaches were assessed. Read More

During active compression-decompression cardiopulmonary resuscitation (ACD-CPR), the rescuer applies traction to the chest between compressions. Under experimental conditions, cardiac output increases, possibly through accentuated intrathoracal pressure fluctuations. ACD-CPR requires specific training and may be more complex to perform than standard CPR. Read More
