Abstract
This invention relates to instruments, particularly medical and research instruments that are used for assessing gas volumes of cavities, particularly, cavities that may exhibit a compliance to changes in pressure, such as in vivo volumes of the lung, thorax, oropharynx and/or nasopharynx.
Claims14
An apparatus for measuring gas volumes of a cavity of unknown compliance in a subject comprising:
- (a) an air cavity with induction means for inducing calibrated mass and volume changes in said air cavity;
- (b) a means for interfacing said air cavity to the volume to be measured;
- (c) a means for measuring air pressure variations in said air cavity;
- (d) a processing means electrically coupled to said induction means and measuring means for calculating the gas volume.
