Optoelectronic plethysmography
From Wikipedia, the free encyclopedia
Optoelectronic Plethysmography is a method to evaluate ventilation through an external measurement of the chest wall surface motion.
This method has been developed at the Bioengineering Department of the Polytechnic of Milan (Italy).
A number of small reflective markers are placed on the thoraco-abdominal surface by hypoallergenic adhesive tape.
A set of specially designed video cameras analyze the chest wall motion. A dedicated software computes the enclosed volume and its variations during breathing.
