WebJan 7, 2024 · Opto-electronic plethysmography (OEP) is a completely non-invasive technique for measuring chest wall volume that also allows for regional differences in expansion and contraction of the thorax to be detected. The basic idea is simple and is the same as is used in cinematic motion-capture systems. WebThe lung volumes, such as total lung capacity (TLC) and residual volume (RV), are very much dependent upon age and height. From age 20 to age 60, the RV may increase by up to 50%, while the TLC remains almost the same. Thus the RV/TLC ratio also increases, above the upper limit of 35% at an early age. burns night order of serviceWebPURPOSE: The diagnosis of obstructive ventilatory defect in asthma is currently based on FEV1/FVC ratio <75%.
