The Owlet Sock has three main readings: child's oxygen level, heart rate, and movement.
Oxygen level refers to how much oxygen is in the blood. The Owlet Sock is designed to notify you if this reading dips below 80%.
Heart Rate is indicated as beats per minute (BPM). A child's heart rates are naturally much faster than adults. The Owlet Sock is designed to notify you if this reading dips below 60 BPM or rises above 220 BPM.
Low Heart Rate Notifications
In an effort to minimize excessive notifications, the Smart Sock 3 uses both beats per minute (BPM) and oxygen readings for Low Heart Rate notifications. For more information, please visit our Knowing if Something's Wrong article.
When your child is moving and we cannot get readings, these wiggling feet will appear and in the app and the green Base Station lights will bounce back and forth.
Movement can impact the quality of readings, so rather than notifying you unnecessarily, the readings and notifications will be momentarily paused until we get quality readings again.
