WebExample of a PVR calculation Taking into account the following determinations: Mean Pulmonary Arterial Pressure = 15 mmHg; Left Atrial Pressure = 12 mmHg; Pulmonary flow, cardiac output = 6.5 L/min. The pulmonary vascular resistance = 80 x (15 – 12) / 6.5 = 36.92 dynes-sec/cm 5. Pulmonary vascular resistance (PVR) WebFlow rates of <10 mL/s have shown a specificity of 70%, a positive predictive value of 70%, and a sensitivity of 47% for BOO. 24 If the patient's condition is not sufficiently suggestive of obstruction (e.g., peak urinary flow [Q max] >10 mL/sec), pressure flow studies should be considered as treatment failure rates are somewhat higher in the ... WebMay 25, 2024 · How to Calculate SVR SVR is calculated by subtracting the right atrial pressure (RAP) or central venous pressure (CVP) from the mean arterial pressure (MAP), dividing by the cardiac output and multiplying by 80.
