Who needs it and why

A rhythm oximeter is a device for measuring the concentration of oxygen in the blood (saturation).

“Normal values of the indicator are within 97-100%, a decrease to 94% is already a sign of moderately severe lung damage, and a decrease in oxygen saturation below 90% is a reason for immediate seeking medical help,” the head of the operating center explained to Gazeta.Ru European Medical Center (EMC) Mikhail Kutsy.

The device is hand-me-down in the diagnosis of coronavirus infection, various diseases of the cardiovascular system, congenital heart disease and other ailments.

“Having a pulse oximeter is very important for people with chronic diseases of the respiratory system and cardiovascular system, as it is possible to assess the saturation and heart rate. In order not to be false with the choice of the device, always pay attention to the certificate and license that must be attached to it, ”said Maria Sergeeva , consultant of the digital medical service Doctor Nearby, physician-therapist .

How to choose

There are several types of pulse oximeters on sale, which are attached either to the finger or to the wrist.

There is no vital variance between the two types of devices, however, today doctors most often use pulse oximeters, which are a clothespin for a finger. This model is also suitable for home use.

It is also worth paying attention to the form factor - a portable, battery-powered pulse oximeter is suitable for home use. There are also non-portable devices that are used in hospitals.

When buying a device, it is important to pay attention to the fact that pulse oximeters for children and adults are different in size. And it is important that the device fits in size.

If a child measures the oxygen level in the blood with a device for an adult, or vice versa, then the indicator may be inaccurate.

The quality of the device itself also plays an important role - it is better to choose well-known brands and check documents.

“It is naive to expect that a device from an unknown manufacturer, bought for two thousand rubles on the Internet, will work like a professional one. Therefore, when buying a device, try to choose devices of well-known brands, and be sure to ask about the presence of a registration certificate from Roszdravnadzor , ”advises Mikhail Kutsy, head of the EMC operations center.

How much is

A pulse oximeter is a fairly simple device, but the presence of some additional functions, for example, built-in memory, makes it more expensive.

So, the simplest model can cost from 500 rubles. Children's pulse oximeters are more expensive, the average price is about 2 thousand rubles. Devices with support for heart rate measurement, memory and other additional functions can cost from 2.5 to 4 thousand rubles.

How to use

The pulse oximeter turns on and is put on your finger. When measuring, it is important to use either the index or middle fingers - then the result will be more accurate.

“Since the measurement is carried out on a finger, the state of blood flow in the limb plays a role. If there are diseases in which it is disturbed, or even if a person's hands are simply frozen, the device will greatly underestimate the readings, ”says Mikhail Kutsyi, head of the EMC Operations Center.
