Pulse Oximeters
Pulse oximeter listings compete on colour screens, waveform graphs and rotating displays. None of that tells you whether the sensor underneath is measuring anything. We judge oximeters on whether owners get a number that changes when the person changes, on whether the brand has an address in India, and on how many of them are still working in month six.

How to choose a pulse oximeter in India
This category has a failure mode that almost no other home device has: it can look like it is working when it is not. A fingertip oximeter shines two wavelengths of light through your finger and reads what comes out the far side. A bad one skips the reading and shows a plausible number anyway, which is why the single most useful thing in the owner reviews of the cheap tier is people reporting a full SpO2 reading off a pen, a rolled-up cloth or an empty clip. A thermometer that fails shows nothing. An oximeter that fails shows 98%, and you go back to sleep.
So the first question is not which features you want, it is whether the sensor is real - and the practical test is free. Clip the device on nothing, or on something that isn’t a finger, the day it arrives. It should say “finger out” or show dashes. If it gives you a saturation, return it that afternoon. After that, the numbers worth weighting are unglamorous: an importer with an actual Indian address on the listing rather than a marketplace brand name, a warranty measured in years rather than the six months several popular models quietly offer, and ordinary AAA cells rather than a sealed battery. Ignore the display-mode count, ignore the number of rotation views, and treat “perfusion index” as a nice-to-have unless you already know what you would do with it. And remember what these devices are for: they are a trend tool for someone managing a known condition, not a diagnostic. A reading you don’t like is a reason to call a doctor, not a reason to buy a second oximeter.
