Pulse Oximeter: What it is for and How to Find it at the Best Price on AliExpress

Keeping regular control of our health is very important, mostly if we practice sports or have any disease. Luckily, there are more and more affordable and reliable household appliances. One of the newest and currently sought after is the oximeter, a small device that allows calculating the level of oxygen saturation in the blood. This information is very important for professional athletes, but also for patients with diseases that affect the respiratory system.

Oximeters have become an extra tool for detecting one of the symptoms of coronavirus. COVID-19 affects the respiratory tract, therefore, it reduces the level of oxygen in the blood. Oximeters are very useful, not only for people in risk groups but for anyone since if the disease is not detected on time, it can cause us to suffer hypoxia (shortness of breath without warning). Even so, having a low oxygen level in the blood (approximately below 93%) is not a confirmation of having coronavirus, but still, using these devices is a good way to control our health, whether or not we have this disease.

How does an oximeter work?

An oximeter is a small device that is placed on the fingertip and measures the oxygen saturation of the blood. It does so employing LED light emitters that send impulses through our skin. Blood has a different wave absorption depending on whether or not it is oxygenated, so oxygen level can be measured effectively without a blood sample. To work properly, nail polish should not be worn when using it. Take into account that a person without pathologies must have more than 95% oxygen in the blood, though this level varies throughout the day. We should always check with our doctor for the results before worrying.

1 – ARSTN Oximeters

This brand is one of the most popular ones. Basically, they only sell oximeters, although with several different models. Some of their models are best sellers on the platform since they have a good value for money and great precision in data collection. You can find them all at this link.

One of their best-selling models stands out for having a LED or OLED screen. Besides measuring oxygen in the blood and pulse, they can also record data or emit sounds to warn us. Although their models are ideal for children from 4 years old, they also have pediatric oximeters for babies. And if you want to record your data on your mobile, you can also find oximeters with Bluetooth.

But we mainly recommend this brand if you are looking for a professional oximeter since they have some models with more advanced technology that allow you to change the probe to fit the finger of babies, children, adults, or even pets. They can show other values ​​such as the perfusion index or the temperature measured through the sensor. Some can be synced to your phone to keep track of measurements.

2 – Yongrow Oximeters

The Yongrow brand has been selling on this platform for more than seven years and specializes in medical products, with a professional service, the possibility of dropshipping and fast shipping in less than 24 hours. You can buy oximeters per unit or in a pack with several devices. You can see them all by clicking here.

Their oximeters measure the oxygen level in the blood and the pulse rate with the conventional finger system. They use CFL technology and reduce light interference to achieve the best measurement accuracy. For a small difference in the price, you can find some oximeters with built-in batteries that can be charged via USB-C to avoid wasting batteries. Their oximeters have international certificates (CE, TUV, FDA, ROHS …), so they are a guarantee of quality.

3 – Elera Oximeters

Elera is another store that specializes in medical products, such as thermometers, blood pressure monitors, and glucose meters. They offer several finger pulse oximeters. One of the advantages of this brand is that they have warehouses in certain countries so that you can receive your purchase faster. Their oximeters are high-quality and make very reliable measurements. You can see them all here.

One of their best-selling models is the typical finger oximeter. This brand has several models of that type, with LED or OLED screen and alarms. They also have some baby and neonatal models, and other handheld oximeters with multiple probes to fit the finger of babies, children, adults, and even pets. Although they are a bit more expensive, they can be useful for families where several members need to use it. Something interesting is that we can see a graph with the variation of the values ​​at the moment of making the measurement.

And finally, if you suffer from apneas during sleep, you will be interested in its apnea control monitor, which warns you in case of low oxygen in your blood and records your pulse. You can choose between a small finger device, similar to the typical oximeter, or an oximeter with a bracelet where we can see the measured data and receive alerts through vibration. Lack of oxygen during apneas is very dangerous, as it increases blood pressure and affects the cardiovascular system. Usually, these pulse oximeters for apnea are very expensive, but the models of this brand are low-priced and very effective.

They have all kinds of health care products, and as for oximeters, they have great models for the whole family. These can be found in their official store, as you can see here.

Their pulse oximeters with Bluetooth are the ones with the most sales since in addition to showing the results of SPO2 and pulse on the screen of the device itself, they are connected to a mobile application compatible with Android or iOS, in which we can consult the records of our pulse and oxygen easily. The measurement is done in just 8 seconds, and thanks to its OLED screen, we can see the results more clearly. They also have other inexpensive finger models, which can display data such as perfusion rate or detect respiratory rate.

They have other interesting models. For example, their bracelet with blood oxygen measurement can be a good purchase for athletes who do outdoor activities such as mountaineering, avoiding suffering from acute mountain sickness (altitude sickness) due to hypoxia. It is also a good option for people with apnea or breathing difficulties who need constant measurement. Besides, it has Bluetooth, so we can look at the values ​​through the brand's application.

Hand oximeter

In this case, the data is displayed on an external monitor while the sensor is still on our finger.

Also, we can see more data on the monitor and even graphics. Some can also be connected via Bluetooth to a provider's application. Find them by clicking here.
