Optoelectronic plethysmography is based on the analysis during breathing of the trajectories of a series of markers positioned on the thoracico-abdominal surface of the patient. The positions in space of these markers are recorded and processed with mathematical models and algorithms by a computing unit that can accurately measure not only volume variations of the whole thoracico-abdominal wall, but also the variations of the various compartments. This detects, for example, any asymmetries in the action of respiratory muscles.
The system can accurately measure current volume, vital capacity, respiratory frequency, duration of the phases of inspiration and exhalation, the average inspiration and exhalation flux and the volumevariations at the end of exhalation.OEP SYSTEM is an innovative examination instrument, non invasive, accurate, easy to use and irreplaceable in the case of non-cooperating patients, moving subjects or in particular environmental conditions.Unlike traditional plethysmographic technologies, OEP System is not affected by humidity and temperature variations and can be used to easily perform measurements for extended periods of time.
