Review on Pulse Oximeter Fingertip: Digital Blood Oxygen Saturation Monitor For Heart Rate & SpO2 Level Monitoring - Portable LCD Pulse Oximeter With Batteries Included by Gary Generale

Purchased this to monitor oxygen levels for COVID-19 after reading about its use. I learned that younger people who do not get admitted to the hospital have been advised to monitor their oxygen levels at home, to make sure that they do not drop below 95. If oxygen drops below that, it is imperative to get to the hospital to avoid having to be put on a ventilator. Hoping that I do not have to say that this device saved my life, but I'm thankful to have it in case I become infected. My parents, who are in their 60's, both tested their oxygen with it, and I feel much safer knowing that I can drive over to their house with this device and quickly assess the situation if they become ill. Oh and it also shows pulse rate.It was also delivered quickly and already has the batteries with it. Overall, I'm extremely happy with this purchase.
