Here you will find everything from the most sophisticated models, such as purchase characteristics, to dispel the most frequent doubts of use.


  • Pulse oximeters or pulse oximeters are medical devices that indirectly measure oxygen saturation in the bloodstream, without the need for finger pricking.
  • One of the main advantages of the new generation models is their easy portability and size, allowing them to be used outside hospitals or medical institutions. In addition, there are models with multiple functions such as heart rate, respiration rate or perfusion index.
  • Accuracy levels, readability and durability are some of the most relevant features to consider when buying an oximeter, in addition to knowing the precautionary measures for the proper functioning of the device.

The best Pulse Oximeter: Our Picks

Buying guide: What you need to know about pulse oximeters

For years now, the portability and affordability of devices that previously assessed vital signs only in hospitals or medical centres to home use has increased. As a result, the wide range of devices available for home use has become an ally for doctors, athletes and patients in monitoring the body, such as pulse oximeters.

One of the main advantages of the new generation models is their easy portability and size allowing them to be used outside hospitals or medical institutions.

What are pulse oximeters?

The main and basic function of a pulse oximeter is to measure the oxygen saturation in the blood. Knowing this saturation is important because it is the oxygen-carrying blood that supplies the tissues with energy or fuel for the proper functioning of the body.

Why is it important to use pulse oximeters?

In the past, pulse oximeters were used not only by patients with cardiac or pulmonary deficiencies, but also by airline pilots and athletes training at high altitude. Now it is being used in more sports disciplines with high intensity / endurance training or where climatic conditions are demanding.

The fact of knowing the oxygen expenditure inside the body has caused not only the health industry to innovate in its products, but also the sports industry to take an interest and market itself due to the multiple benefits it brings. An example of this is the sports wearables that have this function.

Some advantages other than regular monitoring in patients are related to high-intensity training. These include subsequent recovery and adaptation to altitude, since the higher the altitude, the less oxygen in the air, so the body requires inhalations to compensate and avoid dizziness or fainting.

  • Post-training recovery
  • Adaptation in altitude training
  • Follow-up in patients with cardio-pulmonary diseases
  • Prevent dizziness or fainting in a timely manner

Pulse oximeter for home or professional use What to pay attention to?

The classification of pulse oximeters can vary according to the use where the study is carried out, i.e. at home or in hospitals, or by the user profile, by profession or age. Commercially we will focus on the aspects for use at home (or portable) or professionally in medical centres (fixed or stationary).

Portable use Stationary use
Durability in constant monitoring Durability in constant monitoring
Long battery life or power adapter Long battery life or power adapter
Environmental protection High accuracy level
Compact size and light weight Readability
Non-functional alarms
Data storage

These are just a few features to consider depending on the user’s needs; however, additional features can also be found with additional functionality: easy to use for those with no medical experience or familiarity, colour display or computer transmission.

Purchasing criteria

Whether you are a health expert in the process or just unfamiliar, there are important features to consider when purchasing an oximeter; we will classify the different models of oximeters on the market within each criterion to make it easier for you.


Pulse oximeters will vary in characteristics if they are used at home or in hospitals and medical institutes; therefore, there are two types: hand-held or portable.

The former is commonly used at home as it is small and lightweight, has a display screen on the probe, uses batteries and is usually for intermittent use. Its accuracy is best with a strong pulse.

On the other hand, unlike the finger or handheld, the portable is used daily in hospitals, its readings are more accurate, the display of readings is linked by a cable connected to a screen and it is capable of prolonged monitoring.

The catalogue of models and brands for pulse oximeters currently on the market is extensive.

Continuous or on-the-spot monitoring?

This purchase factor is subject to the frequency of use of the device, whether it is sporadic or on the spot or, on the contrary, continuous monitoring.

Models of pulse oximeters for on-the-fly monitoring can be any available on the market, e.g. sensor boards. For continuous monitoring it is very popular to choose wrist or watch monitors, because of their practicality as they are wireless, day and night use and long power durability.

Adults, children or infants

Due to the dimensions of the devices for use with children or babies, it is necessary to look for special brands. The design for them is designed to fit small fingers; they are also available for use on the foot or head as required.

Another reason for the children’s variant is that the limbs are not of the same size and strength for the use of the device. And for something more high-tech, there is the prenatal variant, which is commonly monitored within medical facilities.
