Sensor Life
Sensors can be worn for up to 10 days (238 hours; 240 hours less 2
hours warm-up period). To estimate how long a sensor will work over
10 days, all sensors worn were evaluated to determine how many days/
hours of readings each sensor provided.
For adults, a total of 164 sensors were evaluated. Ninety-four percent
(94%) of the sensors lasted through the end of the entire wear period
(e.g., Day 10) (see Figure 1-A). Among the 164 sensors evaluated, 8
sensors (4.9%) had “early sensor shut-off” where the sensor algorithm
would have detected sensors that did not function as intended and
shut them off.
For pediatrics, a total of 210 sensors were evaluated. Seventy-seven
percent (77%) of the sensors lasted through the end of the entire
wear period (e.g., Day 10) (see Figure 1-B). Among the 210 sensors
evaluated, 28 sensors (13.3%) had “early sensor shut-off” where the
sensor algorithm would have detected sensors that did not function as
intended and shut them off.
