When we inhale, our lungs fill with oxygen, which is then transported throughout the body.At
Conditions such as asthma or COVID-19make it difficult for the body to take in oxygen from the lungs. This causes the percentage of oxygen saturation in the blood to drop to 90% or less, indicating a need for medical attention. In the hospital, doctors monitor this indicator using pulse oximeters - clips that you put on your fingertip or ear. And thanks to the new development of scientists, monitoring can be carried out at home.
A new study shows that smartphonesable to determine the level of blood oxygen saturation with an accuracy of up to 80%. All you have to do is place your finger on the camera and the flash of your smartphone. The software then uses a deep learning algorithm to determine the level of oxygen in the blood.
The team hopes to continue this research by testing the algorithm on more people.
