In this article, we will take a look at some of the best Pulse Oximeter available to buy in 2020. You can buy them online on sites like Amazon and use it to self test on your own.
But before we look into the best Pulse Oximeter, we should first know why we want to use it in the first place. Right? Since knowing what it actually does will help us in making a better decision on which one to buy. Do you agree with me? Great! So then let us do just that. Let us first learn what is the use of a Pulse Oximeter.
What Is A Pulse Oximeter?
A Pulse Oximeter is a medical device used to test and monitor the amount of oxygen present in a person’s blood. So that is what it does. It just looks for the amount of oxygen present in a person’s blood and alert you in case if this drops below a certain level!
Alright. It all sounds great. But here are the next set of question we will have then. Why are we monitoring the amount of Oxygen in the blood in the first place? What is the use of it? What makes it so important?
You must be having these questions right? Great! So let us try to dig further to understand why we need to monitor the amount of Oxygen in our blood in the first place. Alright? Cool! Here we go!
Why to measure oxygen in blood?
So as you all know, we get oxygen into our body by breathing. Right? But why does our body need oxygen in the first place? Hmm..let me explain you.
So here is the thing. You all agree that we need to energy to move around right? But did you know that, that is not the only time we spend energy from our body? Yes, you read that right!
Because, even if we are not moving around and decide to sit in a place, we will still continue to burn energy in our body. So why is that, you ask? That is because the organs in our body also needs energy to function.
So our body organs such as heart, kidney, liver, lungs etc all need to burn some amount of energy in them to continue their function. As a result, we will continue to burn energy even when we are sitting or sleeping idle in a corner of our house!
Alright. We understood all that, but what is the role of oxygen in all this, you ask? Well, that is a great question!
So you see, every time we want to burn energy, we need oxygen to do so! Now, I don’t want to go in detail on why that is the case and bog you down with too much of information.
So if you are really curious about it, I will ask you to go read more about Oxygen from this Wikipedia article. But for the rest of the case, just know that oxygen is required to burn calories to release energy.
Does that make sense? Great! Then let us move on to our next question.
How is oxygen transported in our body?
So now we know that we need oxygen to release energy in our body, right? Cool! But here is the thing. We breath oxygen into our body right.
But how does this get transported to all other parts of our body? Yes, you guessed it right! It is through the blood flowing in our body. So, the blood will carry oxygen along with many other useful things in it through out the body.
So this is the real reason why we want to test the amount of oxygen in our body. Because measuring this will tell us how healthy our body is. And if you have symptoms of sickness, breathing problem or Corona symptoms, you will be able to detect it by measuring the blood oxygen level!
Phew! That was quite a bit of information to read through, right? We know! But without going into this much of detail, it is very difficult to explain the role of measuring oxygen in blood. So we had to do so! But I hope it was all worth it. I hope it was a good learning for you guys!
So now that we know why we need to measure oxygen levels in blood, let us now learn how the Pulse Oximeter helps us in doing that.
So in other words, we will learn know the Pulse Oximeter works. Alright? Now don’t get alarmed when I say this. Because I know that not many of you will have a technical background. Or you people really want to know the nitty gritty details of it. So do not worry. I wont bog you down with any technical details.
We will just learn how a Pulse oximeter works at a higher level. Sounds good? Great! So let us get going then!
How Does A Pulse Oximeter Work?
So we learnt earlier that blood is the transporter of oxygen in out body, right? But I need to clarify this one other thing. The blood carries oxygen using what are called Haemoglobins molecules. So they are the actual transporters of the oxygen in our blood. Like cars on our roads, Alright?
Oxygenated & De-Oxygenated Haemoglobin Molecules
So the haemoglobin molecules having oxygen in them are called oxygenated haemoglobin. While on the other hand, the one which do not have oxygen in them yet are called de-oxygentated haemoglobin.
So why am I talking about all that when learning how a Pulse Oximeter work?
Well, you see the way a Pulse Oximeter works is by using the physical properties of this molecule – haemoglobin.
Wait what? So we need to learn about its physical characteristics now? Hmm…no not really.
I will not bog you down with too many details on the haemoglobin’s physical properties. But what I will do is to focus on only one of it’s physical property – its light absorption property.
So you see, when a haemoglobin molecule is carrying oxygen in it, it can observe all the light rays passed into it. On the other hand, when it does not have oxygen in it, it lets the light rays pass through it.
So it is using this property that the Pulse Oximeter is built.
Wait, how does that work then?
So what happens in a Pulse Oximeter is that you are asked to insert your finger into a slot in it. Now when you do that, the Pulse Oximeter will pass light rays through your finger. It will then try to read the amount of light passed through your finger.
So in that way, it can detect the amount of oxygen present in your blood. Pretty neat to use Physics like that. Isn’t it? 🙂
So now that we have a pretty good understanding of how a Pulse Oximeter works, it is now time for us to see which are the best Pulse Oximeters available in 2020 for us to buy online. Are you ready? Great! Let us go ahead then!
