文摘

Positive pressure ventilation decreases cardiac output by decreasing venous return. In contrast, diaphragm contractions increase venous return. Diaphragm pacing can produce alveloar ventilation without decreasing cardiac output. Added to positive pressure ventilation, diaphragm pacing corrects cardiac output.
