Respiratory monitoring, using a novel flow sensor based on an acoustic principle, has been investigated in 30 patients during postoperative analgesia. Each patient was subjected to monitoring and human observation for 8 hr. The study was performed by independent observers at three clinics. ⋯ More than 800 apnea alarms were noted, using an alarm setting of 30 sec; 61% of the categorized alarms were noted by the observers as true apneas. From the recordings it was shown that the number of alarms can be reduced by a factor of four if the alarm setting is changed to 45 sec. We conclude that the suggested technique, with slight modifications, provides adequate respiratory monitoring of patients during postoperative analgesia.
