Overview
Bedside at home or packed for a trip outdoors, this Santamedical fingertip unit clamps onto a finger and reads blood oxygen saturation and pulse rate at the press of a button. Results appear on an OLED screen that can turn to face the wearer or a helper.
Simple operation is the reason to buy: one button starts a reading and the screen stays legible from a dark bedroom to direct sun. The listing gives no accuracy figure, measuring range or reading memory, so anyone tracking trends has to write numbers down by hand.
Who it's for
Checking blood oxygen on the couch, on a hike or while travelling is what this clip suits, and the lanyard stops it vanishing into a bag. People who need overnight monitoring or recorded history should look for a model that lists memory and alerts.
Pros and cons
- Display stays legible in direct sun
- Single button operation
- Screen rotates for wearer or helper
- Batteries and lanyard come in the box
- Accuracy figures not listed
- No reading memory or app described
- No alarm for low readings mentioned
- Runs on disposable AAA cells
Performance notes
Readings depend on a still hand and a finger seated fully in the clip, since the sensor reads through the fingertip. Cold fingers and movement can delay a stable number. The automatic shutoff ends the session soon after the finger comes out, which saves batteries but means pressing the button again for each check.

Frequently asked questions
Does the Santamedical fingertip oximeter save readings or connect to a phone?
The listing describes live readings on the OLED screen only. No memory, Bluetooth or app is mentioned, so record readings yourself if you need a history.
Can someone else read the Santamedical oximeter screen while it is on my finger?
Yes. The display can show readings in four different directions, so the wearer or a helper can read it the right way up.
Does the Santamedical oximeter work outdoors?
The seller says the OLED display is clear in bright sunlight as well as in the dark, and the unit is light enough to carry on its cord.
How accurate is the Santamedical Generation 2 oximeter?
The seller calls it accurate, but the listing gives no accuracy tolerance or measuring range. Treat readings as a home check and confirm worrying results with a clinician.
