Abstract
A pneumotach is provided that is effective for obtaining accurate flow measurements through a wide range of velocities by measuring substantially linear flow, and which includes a readily disposable element. The pneumotach also includes a holder adapted for readily holding the disposable element in a manner so as to be substantially free of patient contamination, and with transducer capability for detecting pressure and measuring the same at low flow rates. A combined pulmonary functioning measuring kit includes computer and read-out capabilities for selectively receiving input from either spirometer or the pneumotach. The kit is readily assembled and is self-contained.
