The calibration of the strain gauge plethysmograph is in percent volume change. How does this affect measurements?
Blood flow is usually expressed in terms of cc’s of blood flow per 100 cc’s of tissue per minute. This is equivalent to percent per minute. The reason for this is to normalize results so individuals of different sizes can be compared. If a different type of plethysmograph is used which is calibrated in terms of absolute volume change, it would be necessary to calculate the size of the limb in order to normalize the results. © 2008 D.
