Pulse oximeters

Self-monitoring is the basis for maintaining health and well-being. Modern diagnostic medical technology adapts to people's changing lifestyles and keeps up with the times. Pulse oximeters are devices for measuring blood oxygen saturation and heart rate. It is now simple to take measures without going to a clinic because of the development of portable models and their user-friendliness. No medical knowledge is required to decipher the readings. 

Types of pulse oximeters

All pulse oximeters are divided into two main groups: stationary and portable. The first group includes multifunctional devices that measure the level of oxygen in the blood, perfusion, pulse rate. Data is displayed on the screen in the form of graphs. They are deciphered by specialists in the medical institution. Equipment is used in diagnostic centers, clinics, laboratories. With the help of stationary pulse oximeters, doctors monitor the data in dynamics 24 hours a day. Portable models of devices are presented in several options:

  • classic — measure oxygen levels and heart rate;

  • pulse oximeters — read heart rate;

  • heart rate monitors — have additional functions: number of steps, calories burned.  

Popular models are made in finger and wrist format. A separate category includes pulse oximeters that are fixed on the belt. They are used for long-term monitoring of the state of health.
Finger devices are convenient for both hospitals and home use. Manufacturers produce devices for children and adults. Medical pulse oximeters have a compact size, provide accurate measurements. Anyone can monitor saturation from the comfort of their home.

Principle of operation of the pulse oximeter

The portable device has the form of a «clothespin» with a display. Power is provided by batteries. The functionality of the device is based on three factors:

  1. Light source. A special sensor directs light rays for screening.

  2. Photo detector. The task of the element is to receive rays from the source on the opposite side.

  3. Microprocessor. A kind of «brain» that counts incoming and outgoing rays, analyzes, presents data in the form of numbers. 

The work of the pulse oximeter is based on the evaluation of the color of pulsating blood. Red — indicates good oxygen saturation. The device simultaneously records the seconds between pulsations and counts beats per minute. Stationary equipment is connected to a PC, it guarantees highly accurate readings, which are recorded in the form of a photoplethysmogram.

Where to get the best price on pulse oximeters

Bimedis platform offers a wide range of new and used medical equipment at a reasonable price. The service is designed for selling, buying, and exchanging devices. Thanks to the intuitive interface and convenient filter it is easy to make a profitable purchase. 

 

FAQ

What is a pulse oximeter and how can it help me?

A pulse oximeter is a device for determining the degree of oxygen saturation in the blood. The device analyzes the amount of light transmitted, translating the information into numbers. This makes it easy to find out the oxygen saturation of hemoglobin. For healthy people, this percentage ranges from 95 to 100%.  If the saturation is 94% or less, a doctor's consultation and additional diagnostics are necessary. 

How to use a pulse oximeter?

To obtain accurate results, it is important to adhere to the rules:

  1. Determine the device's charge level. 

  2. Clean the sensor if it is dirty.

  3. Put the device on a clean finger 1-2 minutes after turning it on.

  4. It is better to measure without sources of bright light and electromagnetic rays.

  5. You should remain still during use. 

  6. The level of oxygen and heartbeat appears on the screen of the device.

The presence of nail polish and coating on the nails can affect the result of the readings. After the measurement, the pulse oximeter should be turned off and put away. 

How do pulse oximeters work and how accurate are they?

The determination of the saturation level with a pulse oximeter is based on two phenomena. The first is that hemoglobin absorbs light of different wavelengths. The level of absorption depends on the amount of oxygen that hemoglobin captures. The second is that the stream of light from the LED lamp of the device's sensor begins to pulse as it passes through the tissues. The heartbeat changes the volume of the arteries and the intensity of the rays passing through. 

The oximeter emits wavelengths of 660 nm, 940 nm, corresponding to red and infrared light. A hemoglobin molecule can capture up to four oxygen molecules. The level of absorption of light waves depends on this amount. The readings are recorded by a photodetector. Measurements are displayed on the screen of the device in the form of a plethysmogram or numbers. Portable models of devices process the data with the help of a special formula, giving a ready result. An abnormality of 1-2% is allowed.

What factors can affect the accuracy of pulse oximeter measurements?

The accuracy of pulse oximeter measurements depends on a number of factors:

  • correct placement — measurement on the middle finger of the hand;

  • correct fixation;

  • length and covering of fingernails — distortion of data;

  • presence of tattoos, scars, rough scars on the fingertip;

  • low blood pressure — weak pulse;

  • overly bright lighting.

Intense lighting can cause a person's pulse rate to increase. During the measurement, the skin surface should be dry, cleaned of dirt, cosmetics.

Can pulse oximeters be used by medical professionals?

Pulse oximeters are widely used by medical professionals. The device is necessarily present in emergency departments, intensive care units, operating rooms, ambulances. The device is necessary to monitor the patient's condition, with breathing difficulties, during and after anesthesia. Stationary and portable models of pulse oximeters are used in medical institutions.
