The applicability of cathetertip type transducer (Faeltec [○!R] 12D-103) for the measurement of peripheral airway pressure is evaluated in this paper. Four studies, step function test, investigation of amplitude response, quantification of phase angle response and measurement of peripheral airway pressure in vivo, were performed to achieve this goal. These studies have revealed the short time constant (1.5 msec.), a little phase shift (7.8 degree at 10 Hz and 16.5 degree at 20 Hz), the good amplitude response (-3 dB at 25 Hz) and the claear recording of peripheral airway pressure of anesthetized dogs with the forced oscillation method. These results suggest that the cathetertip type transducer is suitable for the measurement of peripheral airway pressure.
