WebHow are woods units calculated? Pulmonary calculations As an example: If Systolic pressure: 120 mmHg, Diastolic pressure: 80 mmHg, Right atrial mean pressure: 3 mmHg, Cardiac output: 5 L/min, Then Mean Arterial Pressure would be: (2 Diastolic pressure + Systolic pressure)/3 = 93.3 mmHg, and Systemic vascular resistance: (93 – 3) / 5 = 18 … WebFeb 2, 2024 · Mean Pulmonary Arterial Pressure: 23 mmHg; Left Atrial Pressure - 4 mmHg; and. Cardiac Output - 6 L/min. PVR = 80 * (23 mmHg - 4 mmHg) / 6 L/min. PVR = 253.3 …
