Abstract
Provided are exemplary devices and methods for increasing cardiopulmonary circulation when performing cardiopulmonary resuscitation. In one exemplary method, a patient's chest is actively compressed during a compression phase. At least some of the respiratory muscles are stimulated to contract during a decompression phase to cause an increase in the magnitude and duration of negative intrathoracic pressure during the decompression phase. In this way, the amount of venous blood flow into the heart and lungs is enhanced.
