这种气压测量方法在以完全无创的方式测量人体潮气量方面是独一无二的。它的应用和准确性受到几个复杂问题的限制。这些措施包括对吸入气体成分的控制、基线稳定性以及吸气和呼气过程的不对称性。描述了一种解决这些问题并便于长期测量的新方法。新的计算，避免了以前的错误，导致该方法系统地低估潮气量，说明，。
The barometric method is unique in permitting measurement of human tidal volume in a totally noninvasive manner. Its application and accuracy were 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.
