Before the COVID pandemic, most of us have hardly known about the oximeter device. But in the current situation, this becomes an important device to keep with you. So, it is essential to understand what a pulse oximeter is? What does it do? And which is the best oximeter in India you can buy?

What is a pulse oximeter?

Pulse Oximeter is a lightweight, small medical device that monitors the supply of oxygen in your body. It accurately reads the oxygen levels in your body and also the heart rate (pulse rate). In this device, you have to clip to your fingertip, and then it sends two wavelengths of light to monitor the pulse rate and how much oxygen is carried out in your body. The levels of oxygen are measured by SPO2 (Blood Oxygen Saturation).

How does it work?

The pulse oximeter has two sensors for sending light wavelengths and an LCD to show the oxygen levels and heart rate. As mentioned earlier, you have to clip this device to your fingertip. The light beams out in a specific wavelength that penetrates the blood and monitors the oxygen level in your body.

What things to keep in mind while using a pulse oximeter?

  • Please turn on the oximeter and wait till it completes internal calibration.
  • Clean the finger or toe before clipping the pulse oximeter.
  • Now, connect the probe to the oximeter and make sure it is not too loose or tightly fit to the device.
  • Wait for a few seconds for the oximeter to detect the oxygen levels and heart rate.
  • The pulse indicator beeps once it detects the pulse. Without the indicator beep, it is not very meaningful to measure the readings.
  • Once the oximeter detects the pulse rate, final readings will show on the screen.

Why should you check your blood oxygen levels?

As everyone is aware that COVID affects the lungs the most, it directly relates to the oxygen supply in the body. Having a low level of oxygen in your body is a red alert! People affected by COVID experience shortness of breath as their lungs are getting filled with pus and fluids. It is known as COVID pneumonia. Suppose you are feeling uneasy or finding issues with your heart rate. In that case, you should immediately check your oxygen levels with the help of the oximeter and consult the doctor accordingly.

How to interpret the readings of a pulse oximeter?

The average pulse rate in adults should be in the range of 60-100 heartbeats per minute. An SPO2 level of 95-99% is generally considered to be an average oxygen level. If you have a higher heart rate or an SPO2 level of less than 94%, you must immediately consult a doctor.

Can I trust the readings of a pulse oximeter?

Pulse oximeter readings are pretty accurate compared to other typical tests like arterial blood gas used in the hospital. There is a +/- 2 percent difference in the actual readings of the oxygen levels. For example, if your reading is 84 percent, then the actual oxygen saturation level might be 82 or 86 percent. The accuracy of the oximeter can be impacted due to slight movements, body temperature, etc.

Conclusion

These are some of the best oximeters available in India right now. Though most of these devices work similarly, there are a few changes in terms of display, and additional tracking like Respiratory Rate is not present in some devices. So, pick the one that best suits your needs.
