If you are having a problem with your oxygen levels, you certainly need a pulse oximeter. It’s a device which is used to perform a pulse oximetry test, which measures the saturation of oxygen in your blood. Actually, it shows how much oxygen is transported through hemoglobin from your lungs to the furthest parts of our body, such as your arms and legs.

Oximeters are not only used in hospitals, but also at home. When purchasing one, it’s very important to know which type is the most suitable for you.  Therefore, you must be informed on this topic in order to make the right choice.

Nowadays, you can read plenty of information on pulse oximetryjust by visiting some website such ashttps://www.klaudiascorner.net/what-is-a-pulse-oximeter-pulse-oximetry-abg-tests/, which can be very helpful in the process of choosing.

If you need to purchase an oximeter, follow these useful tips.

Learn about the types and features

It’s a good idea to do a research on various types of oximeters and their features. The most commonly used model is the fingertip oximeter which is clipped on a finger and provides immediate but accurate results. There is the handheld type, which is slightly more accurate and it’s connected to a small monitor.

The tabletop model is more adequate for hospitals because of its size. For constant tracking of oxygen levels, the best choice is the wrist oximeter, which can be worn when a person sleeps. The fetal model is strictly for babies, who have just arrived on this world and it’s made to fit their tiny fingers.

Apart from choosing the right type, you should also pay attention to its durability. If you need an oximeter for occasional tests choose one that runs on batteries, but if you need it for continuous monitoring, it’s better to buy a plug –in device, so that you don’t have to buy batteries all the time.

Another thing you should consider are its characteristics. For instance, some oximeters use a special light which signals wrong results or obstruction during the test. There are devices which use an alarm to warn people that their oxygen levels are low, if they don’t know how to read the results. Visit thispage to learn how to read oximeter numbers.

Consult your doctor

After doing your research, you shouldn’t purchase one yet. First you need to see your doctor, who is going to help you to decide which oximeter to buy. You’ll explain your needs and the doctor will know what to recommend.

If you need an oximeter to measure oxygen saturation once in a while, then the fingertip type is perfect for you. However, if you need it to monitor your chronic disease, then you’ll probably need one with monitor which will also show your heartrate.

Making the purchase

You can buy an oximeter from a pharmacy or from an online store. When going to the pharmacy, make sure you check if the size of the probe fits your finger. The size is standard for adults, but in some cases it can be too small or too big depending on the size of your fingers. If you make the purchase online, measure the size of your finger and compare it to the size given on the screen.

After the purchase, take the device to your doctor and compare the results on yours and the oximeter in the doctor’s office. If they show same results, your device is good, but if the results are different, you should return it. In order to return it, make sure that the seller offers a return policy.

Taking a good care

You should take a good care of your oximeter by having the batteries charged at all times. Don’t forget to clean the probe with a wet towel and alcohol, as dirt might obstruct the measurement process and show inaccurate results. Keep it in a safe place so it won’t get damaged.


When choosing an oximeter, always do an extensive research and pay a visit to your doctor.

Purchase one with a return policy in case it shows wrong results.

Remember: Take a good care of it in order to function well!
