Dream Sock average oxygen level

New feature

As part of the most recent Owlet Dream App update, a 10-minute historical average of your little one's oxygen level is displayed on the main screen. Oxygen level is always tracked by the Dream Sock as part of our multi-factorial sleep algorithm. Now, for the first time, the Dream App displays a 10-minute historical average of Baby's tracked oxygen levels.

IMPORTANT: Blood oxygen level measurements in the Owlet Dream App are not intended for medical use, including for self-diagnosis or consultation with a doctor. These measurements are only designed for supporting sleep quality and understanding sleep state considerations.

How are average oxygen levels calculated and displayed? Where can I see Baby's levels in my Owlet Dream App?

  • The average oxygen level for the prior 10 minutes is calculated, refreshed, and displayed every 10 minutes. The oxygen level is averaged over 10 minutes. It is not a live oxygen reading.
  • When your little one's Dream Sock is correctly in place, your app displays Tracking, indicating the oxygen level is now tracking for you and the first segment of the historical average oxygen level is being calculated. The next 10-minute average begins preparing to display in the app.

  • After 10 minutes of tracking, the Dream App provides you with the average oxygen level for the previous 10-minute segment. It displays with Avg O2 10 min and the oxygen percentage. This historical average updates every 10 minutes.

  • Tracking displays a percentage of average oxygen level only when it's able to collect a full 10 minutes of oxygen level data.
  • Detailed information is available inside the app by tapping the question mark icon, which displays a functional summary of the Tracking and the 10-minute oxygen history percentage messages.

Frequently Asked Questions

Is the oxygen tracking feature new? Did you always track oxygen?

The Dream Sock always tracks oxygen level as a key indicator of sleep state and sleep quality. However, for this latest Owlet Dream App update, the 10-minute historical average of Baby's oxygen levels display in your Dream App alongside other sleep quality indicators (heart rate, movement, and wakings).

Is this the same tracking style as Smart Sock?

No, it isn't. The Smart Sock feature notifies the user in response to heart rate and oxygen level readings falling outside of preset values. In contrast to the Smart Sock, the Dream Sock employs a sleep solution using a variety of sleep quality indicators such as movement, heart rate, oxygen level, wakings, etc. to determine your child’s sleep state and the quality of sleep they receive. These factors prompt you when your child is uncomfortable or needs your assistance to sleep more soundly.

Does the Dream Sock notify me if my child's oxygen level falls outside preset ranges or if it drops?

No, it doesn't. The Dream Sock is a sleep solution that tracks your child’s sleep state and sleep quality by tracking sleep indicators such as oxygen level. Dream Sock does not send notifications based on oxygen level readings falling outside preset zones. However, Dream Sock sends a sleep assist notification if Baby is uncomfortable or needs assistance to sleep more soundly.

Do I receive an alert if my baby’s oxygen drops?

No. Parents don't receive prompts or notifications based solely on oxygen level readings. However, the oxygen level is tracked as a key sleep indicator and is used in our sleep algorithm to assess Baby’s sleep state and sleep quality. If the tracked sleep indicators indicate that baby is uncomfortable or needs help getting back to sleep, Dream Sock sends a sleep assist prompt to the base station and your Dream App.

Does this show live or real-time oxygen? Why is oxygen displayed in 10-minute averages?

No, the oxygen level displayed is an average of Baby’s readings from the last ten minutes. The Dream App displays a 10-minute historical average to align with the frequency of when our sleep state algorithm updates our sleep-state charts.

Is the oxygen value a rolling average?

No, as displayed, the oxygen level represents the average oxygen level observed over the previous 10 minutes. The value is updated every 10 minutes. If not enough data is compiled yet, Tracking is displayed.

Should I see an oxygen chart in the Dream app?

No, the 10-minute oxygen level historical average displays as a sleep quality indicator. There is no oxygen chart in a sleep session history at this time.

Why does the app show tracking in place of an O2 percentage?

When the Dream Sock is correctly in place, you see Tracking so you know oxygen level is being collected and calculated as the historical average. After 10 minutes of tracking, the Dream App displays the average oxygen level, which is listed in the app as Avg O2 (10 min). The average oxygen level displayed in the Dream App updates every 10 minutes to show the prior 10-minute historical average oxygen level.

Why does Owlet Dream App use oxygen level as a sleep quality indicator? Why does oxygen matter in sleep quality?

The Dream Sock sensor’s technology tracks multiple sleep quality indicators, including wakings, movement, heart rate, and oxygen level. Extensive analysis and data science, which involves evaluating tens of thousands of hours of infant sleep from Owlet’s database, found that a key relationship between oxygen level and sleep states directly informs sleep quality. Because of its direct correlation to sleep state and sleep quality, the oxygen level is tracked by the Owlet Dream Sock and App.
