Response times on urethral pressure profiles: carbon dioxide instrument.
This study shows that the response time between an actual event and a recorded event on a urethral pressure profile is a function of gas flow rate and gas circuit volume. Response times varied from 1.8 to 10.8 sec. Considerable variation was noted between flow setting and actual gas flow; therefore, calibration of the instrument's gas flow meter is recommended.
