Abstract


By using Siregnost FD 91 body plethysmograph, we measured thoracic gas volume (TGVe) at end of expiration in 19 healthy subjects aged 20-43 years in order to compare with functional residual capacity (FRC) measured by closed circuit method.

The results obtained were as follows

1. Mean values of TGVe and FRC were 3.395±0.5851, and 3.398±0.6181, respectively.

2. A advantage of the body phethysmographic method for measuring thoracic gas volume was that it were rapid, safe, and easy to perform, requires no gas sample for chemical analysis, and measured TGVe several times.
