Negative pH values are only for academic exercises. Using the concentrations directly conveys a better sense than the pH scales. The pH scale expands the division between zero and 1 in a linear scale or a compact scale into a large scale for comparison purposes.

WebWhat is normal PVR in woods units? Normal PVR is 100 200 dynes/sec/cm – 5. What is a normal PVR value? A normal value for pulmonary vascular resistance using conventional units is 0.251.6 mmHgmin/l. Pulmonary vascular resistance can also be represented in units of dynes/sec/cm5 (normal = 37-250 dynes/sec/cm5).
