Oximeters are in huge demand in India, as they can help diagnose early signs of the COVID-19 virus. They are becoming part of every Indian household. Probably it’s time to take a leap and buy a pulse oximeter for you and your family as well.
India is currently in a pretty grave situation. We are accounting for nearly half of the World’s COVID cases at this moment. The second wave of the deadly coronavirus has crippled our country. During such a critical stage, we need to step up and take care of ourselves. So let’s learn about the Pulse Oximeter and why you should buy them?
What is a Pulse Oximeter?
A pulse oximeter is a medical device that measures oxygen saturation levels. In simpler words, it quickly and easily monitors the level of oxygen in your blood. More specifically, an oximeter measures the oxygen in pulsating blood. We term the measurements as SpO2. A typical oximeter also measures your heart rate as well.
A pulse oximeter is small in size and is designed like a clip. For running the test, it is usually put on the finger but can be attached to the toe or earlobes as well.
What is Oxygen Saturation?
Hemoglobin is a protein in our red blood cells, that carries oxygen from the lungs to various other body organs and tissues. It is also responsible for carrying carbon dioxide from these organs, back to the lungs.
The hemoglobin molecule that carries the oxygen molecule is called oxygenated hemoglobin while the hemoglobin molecule that has no attached oxygen molecule is called deoxygenated hemoglobin.
So simply put, the percentage of oxygenated hemoglobin available in your blood is called oxygen saturation.
How Pulse Oximeter Works?
A pulse oximeter consists of two parts.
- Two LED’S (Light Emitting Diodes)
One of the LEDs is red colored with a wavelength of 660 nm. The other LED is infrared with a wavelength of 940 nm.
The absorption of these wavelengths significantly differs between the oxygenated hemoglobin molecules and the deoxygenated hemoglobin molecules. The oxygenated hemoglobin molecules absorb more infrared light while allowing the red light to pass through. On the other hand, the deoxygenated hemoglobin molecules absorb more red light while allowing infrared light to pass through.
The finger is placed between the two components. The light is emitted from the oximeter’s LEDs, which partially goes through the finger and leaves the print on the photodetector.
The photodetector processes the received information and calculates the ratio of the red light measurements to the infrared light measurements. This ratio is then converted to Sp02, by the processor via calculations based on Beer-Lambert Law.
What to make of your SpO2 results? How do we valuate the oximeter readings? Lets have a look.
- If your oximeter measures your Sp02 reading levels between 95% to 100%, it is considered NORMAL.
- If the oximeter measures your SpO2 reading level between 91% to 94%, it is considered to be a case of MILD HYPOXEMIA.
- In case your oximeter gives the SpO2 reading level between 86% to 90%, it is considered as MODERATE HYPOXEMIA.
- Lastly, if your oximeter gives you a reading of less than 85%, it is considered as SEVERE HYPOXEMIA.
Things To Consider:
- While running the test, try to keep your finger, stable. Too much movement can produce inaccurate results.
- Cosmetics like nail polish can affect the readings as well. Try to run the test on a clean finger for much more accurate readings.
- Cold hands or poor blood circulation can also give you false readings.
Benefits Of A Pulse Oximeter
A pulse oximeter, traditionally, was found in hospitals. But during this pandemic, it has become a necessity for every household. A quick diagnose with the device, can helps patients get a proper and timely medical assistance. It has various other benefits, such as:
- To monitor oxygen saturation of a vulnerable patient, over a period of time.
- It determines if a patient with asthma, needs any assistance with breathing.
- For monitoring blood oxygen levels for people under anesthesia.
- To determine if a ventilator or oxygen therapy is improving the patient’s oxygen levels or not.
- Various athletes and sportspeople use the readings to monitor their oxygen levels while increased physical and training exercises.
- To offer peace of mind to people suffering from respiratory or cardiovascular problems.
- To monitor the oxygen saturation levels at night time for someone suspected to have sleep apnea.
Medical Condition That Require Oximeter
If you or someone in your family suffer from any of the following medical ailments, it is advisable to keep an oximeter handy.
- ARDS (Acute Respiratory Distress Syndrome)
- Congenital Heart Defects
- Chronic Obstructive Pulmonary Disease (COPD)
- Pneumothorax (Collapsed Lung)
- Lung Disease
- Sleep Apnea
Best Pulse Oximeters in India (As on June 2021)
Hesley Pulse Oximeter
Dr. Trust (Signature Series) Oximeter
BPL Smart Oxy Pulse Oximeter
Vandelay Pulse Oximeter
Mievida Pulse Oximeter
Dr. Vaku Swadesi Pulse Oximeter
Note: You might be able to find few pulse oximeters that range from meager INR499 to INR 1499. Yes, they are cheap, but, remember, you get what you pay for. They are usually pretty generic, made of low-grade components, and have serious reliability issues. They do not stand a test of time and they are usually non-refundable and impossible to get support for. So, it is advisable that you shell out a little extra, but buy a product from a popular brand such as the above mentioned.
This concludes our list of the best pulse oximeters in India. I bought an oximeter of Hesley as well as that of Dr. Trust. I don’t see much difference between the two. Both have been performing perfectly for me. Keeping a check on some aspects of my health has never been this easy. I will recommend any of these oximeters, but I do recommend that you perform a little of your own research as well. End of the day, they all do the same basic job of providing Sp02 levels and heart rate levels. So, go for the best.
Do let me know, which oximeter you preferred from the list and why? Also, feel free to contact me in case you need assistance with your purchase decision.
Stay safe and stay healthy!
