A membrane-free plethysmograph for recording volume changes including microlitres.
A method of plethysmography which does not require an air/water tight chamber is described. The method is sensitive enough to record microlitre volumes/volume changes. Its application in two situations, viz. in experimental (artificial) edema and blood flow measurement in the human hand has been demonstrated.
