摘要: Systemic blood flow during cardiopulmonary resuscitation may result from alterations in intrapleural pressure (IPP), with the heart serving only as a passive conduit. Chest compression simultaneous lung inflation (C + SI) or abdominal binding also increase vascular pressures and cerebral flow. Our study was done to evaluate effects of C+SI without on coronary perfusion (CPP) CPR. Micromanometric were recorded 7 dogs ventricular fibrillation (VF) CPR CPP (aortic minus right atrial pressure). During chest alone, aortic (AoP) (RAP) did not differ significantly. relaxation, AoP (15 ± 4 mm Hg) greater than RAP (3 2 Hg; P
