Practical implementation of the barometric method for measurement of tidal volume.

R A Epstein, M A Epstein, G G Haddad, R B Mellins.   

Abstract

The barometric method is unique in permitting measurement of tidal volume in a totally noninvasive manner. Its application and accuracy have been limited by several complex problems. These include control of inspired gas composition, base-line stability, and asymmetry of processes occurring during inspiration and expiration. A new method is described that addresses these problems and facilitates long-term measurements. New calculations, which avoid previous errors that caused the method to systematically underestimate tidal volume, are illustrated.
