4.0â8.0 L/min. The right ventricular end-diastolic volume (RVEDV) ranges between 100 and 160 mL. The right ventricular end-diastolic volume index (RVEDVI) is calculated by RVEDV/ BSA and ranges between 60 and 100 mL/m 2.
Diastolic pressure is also important in determining coronary perfusion, especially to the left ventricle, where most flow occurs during diastole. Normal coronary artery perfusion pressure is 60 to 80 mm Hg. Perfusion pressures below 50 mmHg threaten myocardial perfusion.
