A pulse oximeter gives you the option to check on the current heart rate status, blood flow, and oxygen saturation levels. Your case will help you identify the type of the oximeter your condition requires.

In case you need an extra solution for eventual dilemmas, here is how you can ensure that you are purchasing the product you need.

We will tell you what the most important features are to look for in a pulse oximeter so that you can eliminate the ones that don’t seem to align with your needs and make the best possible purchasing decision.

Which Things to Consider When Buying a Pulse Oximeter

Accuracy and Speed
Probably the most important features of a pulse oximeter are accuracy and speed. You certainly want to purchase a device that is reliable and provides accurate readings each time you use it. That is why you should look for a reliable brand in the first place.

Oximeters come in a couple of variants, of which we already mentioned finger pulse oximeters. Some other types that are proved to be accurate are:

  • Handheld oximeters (the most commonly used in hospitals),
  • Wrist-worn sensors,
  • Tabletop sensors,
  • Fetal oximeters (made for children use).

All of them are designed to monitor blood oxygen saturation levels as well as pulse rates and are highly accurate.
Additional features
You will definitely find it useful to get a pulse oximeter with additional features that provides you with readings that are more detailed. Some of these features include:

  • Data recording,
  • Mobility,
  • Extended battery life,
  • Alarms,
  • Sensors.

A device with audible alarms is excellent for identifying eventual health abnormalities. It will help you detect the concert at a glance so that you can take the necessary measurements. The history saves feature gives you the option to compare and keep track of previous readings. You will easily notice the improvement if you can liken recordings from the previous period with the most recent results.

As you are making an investment, you will probably expect to get a quality device for the money spent.
Aim for an oximeter that shuts the device automatically after a certain inactive period. Automatic battery preservation mode will also extend the battery life of the device. Customers, especially sportsmen, really appreciate the mobility of the device.

You can keep a record of the oxygen levels while on the go, depending on your needs. In the end, you want a device that is durable and will suit your needs best without breaking the budget.
Just as we mentioned, it is as well important to find a device that comes at a reasonable price while provides you with adequate and accurate readings.

Some of the factors that form the price are brand, material, additional features, and accuracy. The great thing is that you don’t have to spend a significant amount for a decent oximeter. Be careful about warranties and return policies, as these indicate you are working with a reliable brand.

What Is a Pulse Oximeter and What Is Its Purpose

A pulse oximeter measures the proportion of oxygen saturation (SpO2) in the blood, pulse strength, and pulse rate fast and accurately.

In other words, it calculates the proportion of how well parts of the body (arms and legs are furthest from the heart), to which arterial blood flows, are supplied with oxygen. People with COPD or the ones with respiratory health issues find this non-invasive electronic device extremely useful.

The very use of a pulse oximeter is simple and easy. This device most commonly comes in the form of an ear clip or a finger clip, but you can find other varieties for different patient’s needs. You would place the device on a fingertip or an earlobe to conduct the measurement.

The device then measures the absorption of hemoglobin in the patient’s blood and calculates how much oxygen is in his/her blood. It is a small device that gives you the measurement within seconds. Oxygen saturation normally fluctuates during the day.

Readings above 92% are safe, while the optimal oxygen level should reach 97% or higher. Some of the common factors that may result in inaccurate results are cold hands, hand movements, weak pulse, and fingernail polish.

Serious athletes and mountain climbers monitor oxygen levels during workouts. Wearing a pulse oximeter is definitely not necessary during a workout, but it is useful for measuring oxygen levels in case of oxygen reduction at higher altitudes or during strenuous workouts.

However, it is highly recommendable to use a pulse oximeter in case a patient is recovering from a surgery or recent illness, as well for the ones with certain medical conditions such as heart attack, heart failure, pneumonia, asthma, lung cancer, or COPD.

What is more, the main reason for having the insight into oxygen levels is the safety concern. In case a person has low levels of oxygen saturation, that may be hazardous for his/her health and indicates serious pulmonary issues.


Some of the pulse oximeters we mentioned in this article are intended for medical use, while the others have their use in the non-medical sector. It doesn’t matter if you are a professional, as all of them are easy to use and provide a great way to track vital measurements.
