What is blood oxygen?
Oxygen level refers to the amount of oxygen carried by the red blood cells in your blood. It is typically measured as oxygen saturation (SpO2), which is the percentage of oxygen-saturated hemoglobin compared to the total hemoglobin in the blood.
How to take a blood oxygen measurement?
- Make sure that your Sense-U Sock Shoe is snug but comfortable on baby's foot.
- Ensure your baby's foot remains still and in a natural position for at least 15 seconds.
- Please wait without disturbing the baby during this time.
How to activate oxygen notification?
If your baby's blood oxygen level falls below 85%, the Sense-U app will notify you, indicating that your child may be uncomfortable and might need assistance for better sleep.
Things you should know
Blood Oxygen measurements are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes.
Additional factors
Even under ideal conditions, the Sense-U Sock Shoe may not be able to get a reliable blood oxygen measurement every time. For a small percentage of users, various factors may make it impossible to get any blood oxygen measurement.
Skin perfusion (or how much blood flows through skin) can impact measurements. Skin perfusion varies significantly from person to person and can also be impacted by the environment. For example, if the environment is too cold, your baby's foot may have reduced blood flow, making it difficult to obtain an accurate measurement.
Motion is another factor that can affect your ability to get successful background or on-demand measurements. Certain foot positions or excessive movement may also impact measurement accuracy.
If the resting heart rate is too high, the Sense-U Sock Shoe may not be able to obtain a successful blood oxygen measurement.
* The accuracy of blood oxygen measurement is ±3% when worn properly.
