CONTEC CMS50M Fingertip Pulse Oximeter

The heart rate monitor and the oxygen monitor are extremely accurate. I have a very severe, terminal genetic condition and, consequently, have multiple heart issues. I’ve had 5 heart surgeries in the past 2 years and have a Pacemaker. I tested this monitor while I was hooked up to the hospital monitors and it was consistently accurate every time I checked it.It gives me peace of mind to be able to know what’s going on with my heart and oxygen levels. It’s also great because I can record abnormal pulses and oxygen levels throughout the day to show to my team of specialists.

After Being hospitalized with Covid pneumonia I decided I need to have one of these at home for myself I purchased this and it worked really well and when it told me I needed to I sat down and when I was OK I felt better it was just more for peace of mind than anything else it’s a good product

Works great for work

Item did not work at first. Instructions were unclear as to how batteries are installed. They need to be installed + on one side opposed to + on the other side

Works as it should. No issues.

Got this for home use. It was super helpful in keeping check during the covid season.

My wife's fingers are too small for the device to recognize it.
