I'd be very skeptical of these devices. I purchased this exact brand over the summer and it found pulse a 98% oxygen saturation in a baby carrot. I've reviewed and left a picture on amazon. Carrot was alive lol!

Sounds like this is only accurate if you're a vegetable. Pass.

Why would people need to know how much oxygen is in their blood? maybe that's the same kind of people that read Web MD and decide they have some sort of irreversible disease...

Asthma, croup, pneumonia, covid-19... These are some of the medical conditions when it's a good idea to monitor how much oxygen is in the blood.

Do not project your lack of knowledge onto others. There are many reasons to monitor one's responses to different inputs as well as continuous monitoring against a base line or a norm.

Ok, so these devises work because as your blood oxygen percent changes, the way it reflects light changes. So putting this on a carrot and seeing that it says 98% saturation would be expected. Not because it is alive, but because it reflects light the same way your finger would. Imagine shining a flashlight on a big red truck and identifying it as a truck because it's a red truck. This is good. Now imagine shining a light on a red building and calling it a truck because it reflects light back at the same color as the truck. This is bad. But this is what you did with the pulse ox. It's meant to go on your finger and see what color the light is. Put something in front of it that's the same color as your blood would be when it's oxygenated, it will tell you what color it is. It then converts the color into a number. 98% for your carrot. Or 98% if you put it in a normal persons finger.

I'm curious. What was the heart rate of the carrot?

Lol, don't overanalyze. Here's a link to the product. Click on all review pics and you will see it detecting pulse in sharpies and dolls. My carrot had 78 heart rate lol 😂

Because some of us are healthcare pros who have to buy their own equipment.

Hahaha. I take it back. I have an idea of why it might happen, but I think after reviewing the reviews, you might be better off getting something else

I guess become the carrot is kind red. The color tricks the optical sensor. You ever try potato or celery?

The better question is why were you trying to micromanage a carrot and force a pulse ox unit on them? What were you expecting the unit to say? Did you think it would respond " sorry sir, this object is a carrot!". I would be more interested in the reading it gave you so we can compare you and said carrot. Thank you for the stellar input 👌🏽

I like to know the name and basic medical history of things I touch with my mouth. If medical history is not available I conduct tests in-house
