Quizplus · Accepted Answer

Apnea alarms are usually set so the patient will not miss two consecutive machine breaths (apnea time > total cycle time [TCT] and < [TCT F1F1F1S1F1F1F10 2]).The TCT would be 5 sec/cycle [60 sec/12 breaths/min = 5 sec.] Considering that the alarm should be activated after two missed mandatory breaths,then that would be 10 seconds or 2 x TCT.
