Can a pulse oximeter detect COVID19 symptoms?

Those with coronavirus frequently arrive at hospital with low oxygen levels. Therefore, using a pulse oximeter could detect low blood oxygen and therefore a sign of coronavirus. A normal pulse oximeter oxygen level reading is between 95% and 100%; anything below 90% is dangerously low.

How does the Marsden O-100 Pulse Oximeter work?

To use the Marsden O-100, simply clip the device onto the end of your finger. Within seconds the OLED display will show your blood oxygen and pulse rate readings clearly. As it detects heartbeat, the device will beep, and the display will notify you if your readings are normal. When low oxygen level or abnormal heartbeat is detected, the device will give a visual and audible alert.
