Abstract: The compliance of the canine trachea under positive and negative transmural pressures was measured in an in-vivo preparation. The average compliance values found in eight animals were 11.7×10−6 ...

Abstract: The specific compliance of the tracheas of seven anesthetized dogs were measured in vivo under control conditions and with the cervical vagi cut and then stimulated. Specific compliances ranged ...

Abstract: An acoustic plethysmograph intended to measure the body volume of premature infants has been developed using the principle of the Helmholtz resonator, in which the resonance frequency is dependent ...

Abstract: A pulsed ultrasound Doppler velocity meter has been used to map the time varying velocity waveforms in the exposed left coronary arteries of anesthetized ponies. Velocity measurements were made ...
