Pulse oximetry is a non-invasive method of measuring the degree of saturation using a pulse oximeter. Special pulse oximeter probes allow you to measure the pulse rate, the degree of blood oxygen saturation. Some models of devices record an electrocardiogram. For the study, it is important to observe the contact of the probe with the patient's body. Equipment is used to monitor indicators in diseases of the heart, respiratory system, during chronic, acute conditions.
The absorption of light by hemoglobin depends on the degree of oxygen saturation. This phenomenon is the basis of pulse oximetry. The pulse oximeter probe consists of the main elements such as:
emitter of light waves;
detector;
cable.
The device is equipped with LEDs emitting light of infrared and visible spectra. Passing through the tissues of the body area, the light waves of the emitter fall on the photodetector. The absorption of light is different depending on the oxygen content in the blood. The signal is fed to the device via a cable, where it is converted into digital data. The medical pulse oximeter is connected to the patient's monitor for fast and accurate monitoring of the body's condition.
Pulse oximeter probes depending on the manufacturer differ in the degree of sensitivity and functionality. Devices have different forms: clothespins, clips, cuffs, adhesive surfaces (adhesive) for attachment to the body. According to the type of location, there are different types of probes such as:
finger;
nasal;
ear;
forehead;
leg.
There are methods for installation on the forearm or abdominal wall. The devices differ in size, as they are produced for different age categories. There are adult, pediatric, pediatric, universal models. Pulse oximeter neonatal sensor is designed specifically for newborns and has special fasteners.
All types of products are produced for reusable and disposable use. Reusable ones require disinfection after each patient. Disposable ones are used once. For the choice of sensors in the medical institution, it is important to consider the duration of monitoring, patient activity, the possibility of infection in the place of installation, type of attachment, material.
