Pulse Oximeter Fingertip, 4 Data Pulse Oximeter with Respiration, Pulse Oximeter with Respiratory, Pulse Oximeter SpO2 Pulse Rate Count, OLED Oximetry with Batteries and Carry Bag and Lanyard (Pink)

.. how do you very the accuracy of this device? It is pretty fancy and works every time so we have to take the number for what it is and compare it relative to itself. We bought this when my 91 year old dad got covid. My sister works at KP and suggested I get this to check his O2 level. Seems to work well. I can even get my son to use this to get a pulse reading. He refuses to get his pulse taken at the doctor's office but after some convincing he let me out this on his finger when I told him it uses lights to look into his finger.

Easy to use, reading is accurate and small enough to carry around all day working with patients.

I loved this product when I got it, however, the Lazer light inside stopped working after about 30 days of using it. Never dropped, only carried in my scrub pocket and then placed in my desk drawer after shift, no other person used my pulse ox other than me. I am very upset as I am unable to return it as the window of return is closed. I will not recommend this product again.

It doesn’t register the respiration count accurately, but everything else comes in great.

I like that it has a loop on it, so I can attach it to myself and always have it with me. It's great knowing that my blood O² is too low...
