What is oxygen?
The Smart Sock monitors your baby’s oxygen level during sleep to help provide additional awareness and peace of mind.
What Is Blood Oxygen Level
Blood oxygen level, sometimes called oxygen saturation or SpO, is an important indicator that shows how much oxygen is carried in the blood. Oxygen plays a vital role in supporting your baby’s growth, brain development, and overall wellness.
What Is a Normal Oxygen Level?
For healthy babies and toddlers, oxygen saturation levels are generally:
95% to 100% SpO₂
This range is commonly seen in healthy children during rest and sleep.
In many cases, babies spend most of their time within this range when they are calm, sleeping.
Why Oxygen Levels Can Change
It is normal for oxygen readings to vary slightly throughout the day and night. Small changes can happen during:
- Different sleep stages
- Movement or repositioning
- Crying
- Feeding
- Temporary changes in breathing patterns
Brief fluctuations are common and do not always indicate a health concern.
How the Smart Sock Measures Oxygen
The Smart Sock uses gentle light-based sensor technology to estimate oxygen levels through your baby’s skin. The sensor detects how light is absorbed by blood flow and uses this information to estimate oxygen saturation.
This process happens continuously while your baby sleeps.
For best performance:
- Ensure the sock fits properly
- Position the sensor correctly
- Keep the sensor clean and dry
Understanding Oxygen Readings
Oxygen readings are intended to provide helpful wellness insights and trends over time. Because babies naturally move during sleep, occasional variations or temporary gaps in readings can occur.
Factors that may affect readings include:
- Baby movement
- Loose sock placement
- Poor sensor contact
- Cold feet or reduced circulation
- Environmental interference
The readings shown in the app are estimates and may not always perfectly reflect your baby’s exact oxygen level.
Final Thoughts
Understanding oxygen and oxygen saturation can help parents feel more confident when interpreting alerts.
Smart Sock monitoring provides another way to stay aware of your baby's wellness patterns—helping parents gain insights while their little one rests.
