We think that FACELAKE has to work on this.

What is a pulse oximeter?

Oxygen is a critical component of blood. In fact, essential for life. There are two ways to check oxygen in the blood. The first one is the Arterial Blood gases test that includes taking out the blood and checking the level of gases, including the oxygen.

The second and the widely used method of checking the oxygen level in blood is pulse oximetry. It involves checking the amount of oxygen combining with hemoglobin, precisely called oxygen saturation. A pulse oximeter is an instrument that is used for pulse oximetry. The pulse oximeter has become quite common due to its non-invasive and effortless measurement.

Usage of Pulse oximeter

The pulse oximeter is used for assessing a person’s health by checking his or her oxygen saturation levels. Most commonly, with conditions affecting the ability of the heart to pump oxygen and for maladies upsetting the functions of lungs, a pulse oximeter provides an effective method for checking the oxygen level.

Most common use of pulse oximeter is in

  • Congenital Heart anomalies i-e VSD
  • Myocardial Ischemia
  • Heart attack or Failure
  • Asthma
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Pneumonia
  • Lung Cancer, emphysema
  • Anemia
  • Suffocation
  • Sleep Apnea
  • General Anesthesia

Benefits of using pulse oximeter

  • The pulse oximeter is used to check the ability of a person to do a physical activity, which means whether you need extra oxygen while exercising or not.
  • To check whether a lung medicine is working or not.
  • As a management tool for conditions that are affecting the oxygen saturation in the blood.
  • Widely used in hospitals to check neonatal oxygen saturation.
  • To detect the efficacy of different breathing procedures, like oxygen therapy, and ventilations.
  • Used after a surgical procedure, especially after General Anesthesia, to assess patient health.
  • To check whether a person has sleep apnea or not.

How does a pulse oximeter work?

  • A pulse oximeter uses light as a source to measure oxygen saturation in your blood. The pulse oximeter used in hospitals and in-home use the same basic principle

    On a pulse oximeter, there is a source other is the source and a sensor. Light emits from the source, and enter your RBC. Red Blood Cells have the capacity to absorb light due to the presence of a large amount of oxygen. This absorption of light tells us how much SpO2 is; there in your blood. It is a non-invasive procedure and no pinching or pain at all.

    Moreover, pulse oximeters are reasonably accurate. However, you should expect tolerance of 2%. This means that, if your reading is 92%, your oxygen saturation can lie anywhere between 90 and 94.

Guide on using a pulse oximeter

Finger Pulse oximeters are most common in clinical settings as well for home use. However, there are certain things you should taking care of in order to make your reading precise.

These guidelines are for using a pulse oximeter in your home. In a hospital or clinic, your healthcare provider will be taking care of all these things.

  • You should make sure the area you have chosen to take reading must have proper blood flow.
  • Make sure your hand is warm, relaxed, and held below the level of your heart.

  • Avoid vibration, hand movement, and vibrant environment, especially infrared light sources, to make your readings accurate.
  • Make sure to take reading for 3-5min for better results.
  • Whenever you are gasping for breath like after exercise, make sure to take a reading on different hands for a reliable result.

Tips and Precautions for buying a pulse oximeter

There is a difference between the pulse oximeter used clinically and in-home or sports. Clinical or medical pulse oximeters are only available after a prescription. However, this doesn’t mean you can’t use a pulse oximeter in your home.

If you have some medical condition, your physician will recommend a pulse oximeter, and you should use that. However, if you’re an athlete or senior and want to check or maintain a record of you can go with sports pulse oximeters. Moreover, sports pulse oximeters are as accurate as clinical oximeters. So, all these tips are for buying a pulse oximeter for home and sports usage.

Tips and Precautions for buying a pulse oximeter

While buying a medical device or equipment, there are always some considerations. These tips can save from trouble also help in selecting the thing quickly. Here are a few while buying a pulse oximeter.


In the choice of 99% health-related devices, accuracy will always come first. The reason is that the accuracy is related to the proper functioning of the product. You already know the function of a pulse oximeter, it will be futile if it doesn’t give accurate results.

But the big question is, how would you know a pulse oximeter is accurate? Well, for this you’ve to trust someone. We, TheMedMo, can the one. After considering hundreds of pulse oximeter in the market, and reading reviews of almost all. We’ve selected the ten best for you. Moreover, we have used many of them and compared them with the medical oximeter used clinically. So, you can trust us in choosing an accurate pulse oximeter.


Both the display and readability are connected. If you see a pulse oximeter, the first thing you notice is the screen. The bigger the screen is, the easier it will be to read. Keep in mind that when you buy a pulse oximeter, these two things should be in your mind.

But when readability vs display comparison comes in front of you, we recommend you to choose readability. There a lot of high-quality pulse oximeters that have relatively smaller displays, but the big digits compromise the small display.

So, always make sure that the pulse oximeter you’re buying has enough readability that makes reading effortless. A good thing that might help you is, while reviewing all the pulse oximeter, we’ve mentioned each thing separately. We hope this thing will prove beneficial.


Normally, for buying a home pulse oximeter, usage possesses a value. A lot of people consider a good pulse oximeter as an essential part of a first aid kit. In case you’re buying a personal pulse oximeter, no need to consider using.

However, while buying for home, make sure the pulse oximeter is feasible for both adults as well as for children. A lot of pulse oximeter in our “best pulse oximeter” list fulfills the usage requirement; you can consider them a choice.


While looking for a good pulse oximeter, style is one of the most neglected factors. If you’re a gym or sports enthusiast, you should always consider an accurate and stylish pulse oximeter. Choosing a color also comes under style.

We suggest you choose the style according to the requirement. If you want a pediatric pulse oximeter, always look for some vivid color oximeter. While for adults, prefer a dull color to make look pulse oximeter more compact. The more innovative the pulse oximeter is more stylish; it will be. However, it is better if you sync style with usage, this will help you choose a better pulse oximeter.


Companies are making sure that all the modern pulse oximeters are portable and easy to carry. One of the reasons why finger and ring pulse oximeter became so common is that they are effortless to carry with you.

If you’re buying a sports pulse oximeter, you might also need it for travel. It will be good if you choose some small and compact oximeter, so that you can easily put in the bag, without the fear of being damaged. This thing is no longer a major issue, as a majority of new pulse oximeter are portable.


Alarms are essential; they keep you alert as well as help restraining within the limit. For buying pulse oximeter, especially for overnight monitoring, this thing holds a key place. Having an alarm is important because it will awake you whenever your oxygen levels are low.

For normal usage pulse oximeter, alarms are not as important as you might the limits of normal oxygen saturation. Besides this, many companies manufacture pulse oximeters that display normal levels on the screen after every recording. In such cases, you don’t have to worry about alarms. While for buying a pulse oximeter for continuous monitoring, alarms are exceptionally important.


To a considerable extent, durability depends upon the built-quality, somehow upon the brand. Sometimes, in the clinical setting, pulse oximeters are disposed of after usage, but they are inexpensive. While for home or sports use, the majority of people go with quality and expensive products. So, durability becomes an important factor in the choice of the best pulse oximeter.

Moreover, a lot of people think that the brand is behind the durability. But we are not a fan of this hypothesis. Some newly coming pulse oximeters last longer than many famous ones. We strongly believe that you use it, determine the life of pulse-oximeter. In our list, we considered the warranty as a decisive factor for durability.

Memory & Battery

Though these two seems different thing, yet they are somehow linked. A lot of people neglect memory while buying a pulse oximeter, as it’s not their requirement. However, people who need continuous monitoring of their oxygen saturation should keep memory an important factor. The memory includes both built-in storing capacity of a pulse oximeter and syncing this memory with a device.

Modern pulse oximeters have a built-in memory that you use to track a record of your O2 saturation. If you’re an athlete, you can also consider this thing while buying a pulse oximeter. In short, pulse oximeters having a built-in function to keep a record are important for one group of people.

However, the battery is important for everyone. We consider only those pulse oximeter worthy that has, at least, more than overall 25 hours of battery life or more 12 hours continuous monitoring. The interesting part is those pulse oximeters that have the ability to keep a record; they have short battery life. So, you have to keep a balance between battery and memory.

Warranty and Support

Different oximeter comes warranties with different time-period as well as the type. You can have a look at this. But the thing we suggest you do is that always opt for those brands, which always has good customer support.

There are many brands that you take the product back if you find any flaw, though they don’t give any formal warranties. But how will be you, which brand gives the best customer support? We’re here to help you. While reviewing each product, we have not only kept this thing in mind but also mentioned it in time to time. Still, if you’re confused, you can just put your queries in a comment, and our team will eradicate it.


For personal pulse oximeters, the price can be important as your usage is limited. But now, for everyone, price is not an issue. You can buy a pulse oximeter from 30$ to 300$. So, whatever your budget, you will always get what you need. We hope our price grading scale will help you select an appropriate pulse oximeter.
