Plethysmography
Alternate Names : Respiratory inductance plethysmography, Penile pulse volume recording
Definition ...
Plethysmography is a test used to measure changes in blood flow or air volume in different parts of the body. It may be done to check for blood clots in the arms and legs, or to measure how much air you can hold in your lungs.

Plethysmography refers to a method used to find problems with blood flow in the body.
photoplethysmography (PPG) - an examination comparable to the ankle brachial index except that it uses a very tiny blood pressure cuff around the toe and a PPG sensor (infrared light to evaluate blood flow near the surface of the skin) to record ...

Plethysmography is a test used to measure changes in volume in different parts of the body. These changes in volume help check blood flow in many body parts.
Impedance plethysmography: Electrodes detect volume changes within veins. Because this test detects clots no better than ultrasound and is harder to perform, it is rarely used.

IPG (impedance plethysmography) measures vein function in the arm or leg. Your healthcare provider or a technologist will place a pressure cuff on your arm or leg and measure how fast the veins empty.

Plethysmography, which measures changes in blood volume in the extremities, also may be used to evaluate the presence of venous obstruction. Less often, a venogram, an x-ray of the veins following dye injection (venogram) may be performed.
Your doctor may also recommend a test called <><><><><><> plethysmography (pleh-THIS-mog-ra-fee) to determine the severity of backwards blood flow (reflux) in the veins.
In many cases the diagnosis can only be established by investigation such as ultrasonography (Ultrasound Doppler measurement) or plethysmography (measurement of the volume of the limb).
Some PFTs, such as thoracic gas volume or other lung volume measurements, may be determined by plethysmography.
