Our our bodies want plenty of oxygen to perform, and healthy folks have at the least 95% oxygen saturation all the time. Conditions like asthma or COVID-19 make it harder for our bodies to absorb oxygen from the lungs. This results in oxygen saturation percentages that drop to 90% or below, an indication that medical consideration is needed. In a clinic, doctors monitor oxygen saturation utilizing pulse oximeters - these clips you put over your fingertip or ear. But monitoring oxygen saturation at dwelling a number of occasions a day might help patients keep an eye on COVID signs, for example. In a proof-of-principle study, University of Washington and University of California San Diego researchers have proven that smartphones are able to detecting blood oxygen saturation ranges down to 70%. This is the lowest value that pulse oximeters ought to be able to measure, as really helpful by the U.S. |
