WebThe normal coronary vascular bed usually autoregulates over a range of systemic arterial pressures from 60 to 140 mmHg. Above or below these limits, autoregulation fails and … WebCoronary Perfusion Pressure (CPP) = Aortic Diastolic Pressure – Left Ventricular end-diastolic Pressure (LVEDP) CPP is based on diastolic pressures because the left ventricular myocardium gets perfused during diastole rather than systole. Webcontribution to LVEDP is shown in Figure 2, which demonstrates the fall in LVEDP associated with a reduction of the coronary perfusion pressure. At the mark, the perfusion line was clamped, and coronary perfusion pressure fell until coronary flow ceased. This decrease in pressure and flow was associated with a drop in the LV … district nurses derbyshire contact number
