Pulse oximetry is a method of determining the level of oxygen saturation of arterial blood (saturation). Its level is measured by a oxygen measuring device. After receiving results, it is possible to identify diseases in time and immediately prescribe oxygen therapy.
There are several types of this device:
– Stationary monitor is a pulse oximeter used in hospitals that provides high-precision measurements that are recorded in the form of various graphs, for example, a photoplethysmogram. Such devices are connected to a PC;
– The wrist or finger oximeter is used at home and is portable, due to it’s miniature size. Such device can always be at hand – on a walk or travel. A finger oxygen monitor is so small, it will fit in the small lighter pocket in your jeans.
The main requirement for any oxygen level checker is the maximum accuracy of tests. It is the most important difference between cheap and pricy pulse ox monitor. They also usually exclude the negative impact of the electromagnetic field created by other objects around and the slightest movement of the sensor. The o2 saturation levels monitor is distinguished by the accuracy of measurements and indications compared to others, which can really differ in terms of any fingertip pulse oximeter. The “clothespin” sensor, which is used in most medical pulse oximeters, will also greatly facilitate the measurement task. So, basically, the price is defined by the device accuracy, size, portability, material and extra features, like connecting to your phone health apps.
In good clinics for monitoring health conditions, they prefer to use stationary models equipped with external sensors. Such devices display the shape of the pulse volume wave on the graphic screen and on oxygen level monitor, display the blood flow in the area where the sensor is installed. The most versatile models transfer data via Bluetooth to a PC.
Reviews of the finger blood oxygen sensor indicate that it is the most optimal for use in everyday life. It is accurate and easy to use. A portable oxygen meter finger can be significantly less expensive than some stationary devices. To keep the oxygen level reader for finger from causing discomfort, it should not press on your fingertip too hard. In addition, it is imperative to find out how long it can work in a continuous mode, especially if monitoring studies are carried out to determine the indicator in dynamics. Such studies may be necessary when the indicator has fallen to 90%, since a fall below this value indicates serious violations.
The blood oxygen monitor is used in the diagnosis and a wide selection of treatment for cardiological and neurological patients.
The device is used in areas like:
– Pulmonology – to identify pathologies of the respiratory tract, lungs and pleura;
– Anesthesiology – to monitor the patient’s condition during surgery, recover from anesthesia, as well as to confirm cyanosis of the skin due to insufficient oxygen in the blood;
– Pediatrics – to diagnose the onset of pneumonia in children with ARVI and predict an asthmatic attack;
– Sports medicine – to improve the efficiency of training without harm to health.
– Pediatric pulse oximeter – also known as infant pulse oximeter are used for monitoring children blood o2 level.
A oxygen level tester is also useful in a home medicine cabinet in the following cases:
– Heart failure;
– Chronic lung disease;
– Monitoring the therapy of respiratory arrest during sleep by saturation during the night;
– Monitoring the situation in case of oxygen deficiency;
– Control of the body’s response to physical activity in terms of saturation.
– Gathering statistics about children blood quality using special baby pulse oximeter
You can quickly and profitably choose and order a blood pulse oxygen meter on our website, since we have many different variation and options to fit all your needs. Although you have to define several things yourself, to make the best decision:
You can buy pulse ox reader in our specialized physical therapy store alongside with any other required products, but it is important to pay attention to the following parameters while choosing ox reader:
✓ Quick start
✓ Small energy consumption;
✓ Clear display of the result – large numbers, color display, the ability to change the brightness of the screen, readable angle display;
✓ Sensor shape – a “clothespin” will be the best choice;
✓ Impact resistance.
During use and transportation, protect the product from dampness, shock, too low or high temperatures, powerful light sources and contact with explosives. The warranty does not cover if the malfunction is due to improper use or caused by damage to the device due to the fault of the buyer.
Q: What is SpO2?
Answer: SpO2 (saturation) is the level of oxygen saturation in the blood, or the amount of oxygen bound to hemoglobin cells in the circulatory system.
Q: What is the normal range of SpO2 values for healthy people?
Answer: The normal range varies from person to person, usually 96% or more, if your reading is lower, please see the doctor.
Q: Is the displayed SpO2 values changing over time normal?
Answer: It is absolutely natural that the measured SpO2 values change according to the changing physiological conditions of the patient.
Q: What if SpO2 are not displayed?
Answer: Don’t shake your finger, keep calm while measuring. Also, do not use the pulse oximeter and tonometer for simultaneous measurements on one hand.
Question: What if the pulse oximeter gets wet?
Answer: Take out the batteries and completely dry the device with a hair dryer.
Q: How can I check if the pulse oximeter is measuring SPO2?
Answer: Hold your breath for a while (50 seconds or more), if the SpO2 reading decreases significantly, this means that the SpO2 reading is indeed reflecting a change in physiological state.
