A study was performed to develop and test the feasibility of optoelectronic plethysmography (OEP) analysis of the chest wall (CW) in constrained postures (supine and prone) typical for critically ill patients. In ten normal subjects, CW volume changes measured during quiet (QB) and deep (DB) breathing on rigid and soft supports were compared. Results confirm the feasibility of OEP as an attractive tool for the analysis of patients who are not able to maintain other postures than supine or prone.
