Pulse Oximeter

Pulse Oximeter

I've been told OTC pulse oximeter can be 4% off. So it could be 4% lower than indicated or 4% higher. Kind of hard to purchase an FDA approved one.

Tb: I do agree w/SpriggsLinda.I usually encourage people to go to any pharmacy or online.I tell them it d/n need to be costly. Seek an oximeter that will measure BOTH oxygen and pulse/hbm-heartbeats per minute. I am in a facility and mine matches exactly my nurses every day. So, I d/n see any 4% "off". PatV

The $19.00 was portable.

4% seriously walking in your house can change it that much. Even the ones at the doctors can be off. They only calibrate them like once a year. Theres programs you can put on your phone to check pulse so you can compare them and see how close they are to what you got counting your pulse.
