Health condition(s) or Problem(s) studiedhealthy adult volunteers
Date of first enrollment2016/04/01
Target sample size50

Intervention(s)The volunteers are applied sensors of Masimo New Radical-7 and Nellcor PM1000N. They breathe at the rate of 12/min by the metronome for 3 min and then they stop breathing for 15-30 sec. If apnea is detected by either the monitor, breathing is resumed. When they feel dyspnea, they may resume breathing. We record below. Time until apnea alarm after the volunteer stop regular breathing. Time until showing respiratory rate on the monitor, and diminished alarm when they resume breathing. RR, oxygen saturation and pulse rate every 30 seconds. Research time is about 15 minutes.

Outcome(s)

Primary OutcomeTime until detecting apnea by either the monitor after the volunteer stop regular breathing.
Secondary OutcomeRespiratory rate(RR) during regular breathing Time until showing RR and diminished alarm of the monitor Change of oxygen saturation by apnea
