First, pause and take a deep breath. After we breathe in, our lungs fill with oxygen, which is distributed to our purple blood cells for transportation all through our our bodies. Our bodies need a whole lot of oxygen to operate, and healthy folks have at least 95% oxygen saturation all the time. Conditions like asthma or COVID-19 make it tougher for our bodies to absorb oxygen from the lungs.
This results in oxygen saturation percentages that drop to 90% or under, a sign that medical consideration is required. In a clinic, docs monitor oxygen saturation using pulse oximeters - those clips you place over your fingertip or ear. But monitoring oxygen saturation at house a number of instances a day might help patients regulate COVID signs, for instance. In a proof-of-precept study, University of Washington and University of California San Diego researchers have proven that smartphones are able to detecting blood oxygen saturation levels all the way down to 70%. That is the bottom value that pulse oximeters ought to have the ability to measure, as recommended by the U.S.
