Optoelectronic plethysmography
Optoelectronic plethysmography (pronunciation: op-toh-ee-lek-tron-ik pleth-iz-mog-ruh-fee) is a non-invasive method used to measure changes in the volume of an organ or the whole body. This technique is often used in the field of Respiratory Physiology to measure the volume of the lungs.
Etymology
The term "optoelectronic" is derived from the words "optical" and "electronic", referring to the use of light and electronic systems in this technique. "Plethysmography" comes from the Greek words "plethysmos" (increase) and "graphy" (writing), indicating the measurement of changes in volume.
Procedure
Optoelectronic plethysmography involves the use of multiple cameras to capture the movement of markers placed on the skin surface. The data collected is then used to reconstruct a three-dimensional model of the chest wall, allowing for the measurement of lung volume changes.
