Phones can measure oxygen levels in blood
Smartphones can be used to triage patients by measuring oxygen levels in their blood, according to a study.
Scientists placed volunteers’ finger over phone cameras and activated the flash while recording video. They then used Artificial Intelligence (AI) to detect oxygen levels, via flow patterns.
The method was 80 per cent accurate when the blood oxygen level of young volunteers was reduced.
Jason Hoffman, a doctoral student who co-led the study, said: “With our test, we are able to gather 15 minutes of data from each subject.
“Our data shows that smartphones could work well in the critical threshold range.”
