Owlet Dream Sock - Technical Information; Data Processing and Update Delays (continued); Alarm Signal Generation Delay; SpO2 and Pulse Rate Performance

Alarm
Alarm Condition
Alarm Condition Delay
High Priority
Oxygen has dropped below the Low Oxygen Threshold (80% SpO2)
10 seconds
Pulse Rate has fallen below the Low Pulse Rate Threshold (50 bpm)
10 seconds
Pulse Rate has exceeded the High Pulse Rate Threshold (220 bpm)
10 seconds
Medium Priority
Sensor is disconnected from the base station for 60 seconds
(connection issue)
1
60 +/- 3 seconds
The data has not updated for more than 90 seconds and there is no
excessive movement OR the data has not updated for more than 4
minutes and there is excessive movement (Difficulty getting reading)
1
90 +/- 5 seconds (no excessive motion)
4 mins +/- 5 seconds (excessive motion)
Sensor has fallen off the baby (check sensor placement)
1
60 +/- 3 seconds
Base Station has lost power
Less than 5 seconds
Low Priority
Sensor battery is low (Approximately 50 minutes or less)
Less than 5 seconds
1
Sensor has a 120 second delay when removed from Base Station which must be met for these conditions to occur.
15.5 Alarm Signal Generation Delay (Time from alarm condition to alarm signal)
The Base Station controls the alarms and there is no measurable delay in signal generation within the Base Station or in sending the
data to the mobile device. There is less than a 3 second delay in signal generation by the App when connected to the Base Station.
15.6 SpO2 and Pulse Rate Display Ranges and Performance
The SpO2 determined by the Sensor shall be accurate to within ±3% Arms over a range of 70% to 100% Oxygen Saturation under
non-motion conditions.
The Pulse Rate determined by the Sensor shall be accurate to within ±3 bpm over a range of 30 bpm to 300 bpm under non-motion
conditions.*
