It is very important to have the best pulse oximeter in India. Finding the best pulse oximeter in India can also cause a lot of confusion as there are so many options.
There should be a pulse oximeter in your house so that you can monitor the health of your family members.
Health problems like shortness of breath, low oxygen saturation, oxygen flow to the lungs (perfusion index)
Therefore, it is very important that each family carry a pulse oximeter with them. Here we have listed the best pulse oximeter for home use in India.
Types of pulse oximeter
When it comes to different types of pulse oximeters, there are two types: 1) medical grade and 2) sports and home use.
Both can be called a fingertip pulse oximeter because the finger is the most common site used to achieve a reading.
Medical grade pulse oximeters are used by physicians, respiratory therapists, and medical professionals in a clinical setting. They can only be purchased from medical supply manufacturers.
When it comes to home use, it basically comes down to different brands. This article focuses on helping you choose the right type for you.
How does a pulse oximeter work?
The pulse oximeter operates on a simple but elegant principle. Blood absorbs light and there is a clear distinction between wavelengths that pass through oxygenated and deoxygenated blood.
The pulse oximeter’s clip has a transmitting light source that emits a broad spectrum of light.
At the other end, there is a receiver that measures how much light passes through it.
The diode at the receiving end is capable of detecting the wavelength of light. The internal circuitry and processing components of the pulse oximeter also perform some calculations.
The device must compensate for the absorption of ambient light, finger size, and other tissues.
A reference curve is stored in device memory to check and normalize incoming readings. This increases the accuracy of the results.
What does a pulse oximeter measure?
Pulse oximeters primarily measure the percentage of arterial oxygen. In more precise terms, it is the amount of oxygen taken up by blood hemoglobin. This is known as SpO2.
Another way to view results as oxygen saturation. It is an expression of the relationship between oxygenated and deoxygenated blood.
There are parameters that are obtained along the way after measuring oxygen saturation. Heart rate (HR) is automatically calculated with oxygen percentage.
HR and SpO2 complement each other, and physicians read this double parameter quite informative.
How to use pulse oximeter?
The best thing about pulse oximetry is that it is non-invasive. In the past, doctors had to draw blood from a patient and run various tests to ascertain the percentage of oxygen saturation.
Using a pulse oximeter is very simple. You place it on your right middle, toe or earlobe. Some models are surface probes that can be placed on the forehead or chest.
To get reliable, realistic readings, try to minimize the patient’s movement as much as possible. Also, if you are using a finger clip, make sure there is no nail polish on it.
These simple measurements are sufficient to obtain an accurate representation of arterial blood oxygen saturation.
Readings are displayed after a few seconds, and this is another important feature in pulse oximetry. It is useful in emergencies and in situations where continuous real-time monitoring of vital signs of the patient is necessary.
