Measurement of airway resistance in awake cats.
Airway resistance (Raw) measurement with continuous recording was studied in 10 awake cats. The method used was a transducer enabling to incorporate additive resistances by rotating blind. The signals were processed electronically. Part of the measuring device in a pneumotachographic transducer (measurement V') and VT is obtained by integrating V'. Values for mean Raw were read in both parts of the breathing cycle. The experiments have shown that the method could be used in awake cats. Values for mean Rawinsp. were 1.3 +/- 0.24 kPa.l-1.s, Rawexp. of 1.43 +/- 0.26 kPa.l-1.s, end-inspiratory Raw was 1.44 +/- 0.33 kPa.l-1.s and end-expiratory Raw of 1.49 +/- 0.31 kPa.l-1.s.
