The limb is inserted into a fluid-filled watertight casing (oncometer) and the pressure variations in the fluid are recorded.An apparatus for estimating changes in the size of any part placed in the apparatus; in this way changes in the volume of blood in a part can be measured. For example, researchers may use a penis plethysmograph to measure their subjects’ ability to respond sexually to certain stimuli.A device for finding variations in the size of a part owing to variations in the amount of blood passing through or contained in the part.The use of a plethysmograph to record the changes in volume of an organ or extremity.A diagnostic examination involving a patient being seated within a specialized enclosure known as a plethysmograph, where they breathe through a mouthpiece. During this procedure, pressure and air flow measurements are gathered to assess the total volume of the lungs.A method for approximating blood circulation within vessels by gauging alterations in the dimensions of a body region. Penile plethysmography is occasionally employed to examine erectile dysfunction in men, determining if erections occur during sleep.
