Many of you would have come across Pulse Oximeters either personally or have seen doctors using it on someone. They are the perfect device to current your oxygen levels and helps prevent emergency situations. There is a wide range of Pulse oximeter online and offline available, to ensure at home monitoring.

They are clip on devices that measures the oxygen level (oxygen saturation) of the blood. And are mostly used by people with respiratory or cardiovascular conditions.

In this blog, we will cover all the aspects of Pulse Oximetry like how it works, its benefits and few tips for you to get accurate oxygen results.

What is a Pulse Oximeter?

Oxygen is not just important for breathing. Each and every cell of the body needs oxygen to survive. Without it, they began to malfunction and then die. Cell death is a serious problem that can cause severe health problems and finally lead to organ failure.

So, for the normal functioning of the body, it is very important that one has to maintain their oxygen level to be at optimum and that is at 95%.

A fingertip pulse oximeter is a small, light in weight and highly portable device that measures the percentage of oxygen in the blood and the term Oxygen saturation means how much oxygen is getting to the organs.

Pulse Oximeter: How it Works?

Pulse Oximeter use a light source to measure the oxygen saturation. A clip-like device called a probe attaches painlessly to the fingertip, sending two wavelengths of light through the finger to measure the pulse rate and the percentage of oxygen in the system.

The oximeter works by shining a light through the skin. The light then falls through to a detector, positioned on the other side of the skin. The amount of light that is absorbed by the blood indicates the actual oxygen saturation.

Pulse Oximeter Readings

Before buying a pulse oximetry, it is very important to know how to read a pulse oximeter. The value next to the SpO2 sign is the oxygen saturation levels, which should be in between 94% to 99%. The readings below 90% generally indicate acute respiratory failure. 

The pulse rate on the oximeter measures the number of heart beats in a minute. It is usually represented by a heart sign. The average pulse rate for an adult ranges from 60 to 100, whereas in kids the number is higher.

Uses and Benefits

Apart from measuring Pulse rate and oxygen levels, pulse oximetry is also used to monitor the safety of physical activity in people with cardiovascular or respiratory problems

Its other benefits are:

• Pulse oximeter for babies is used to monitor the oxygen levels in infants in neonatal intensive care units.
• To monitor oxygen saturation levels in people under anaesthesia.
• They are also used to check how well lung medicines are working.
• To monitor oxygen levels in people with conditions like Heart attack, chronic obstructive pulmonary disease (COPD), Anaemia, Asthma and lung cancer.

Some of the Best Pulse Oximeter Machine

To get the accurate readings of your oxygen level, it is important to select the right device. Because not every device available in the market provides reliable and correct readings.

Listed below are some of the best pulse oximeters:

Accusure Pulse Oximeter FS10C

The device ensures an easy, painless measure of arterial oxygen saturation (SpO2) and pulse. The SpO2 is the measure of how well oxygen travels to parts of the body furthest from the heart, such as the arms and legs.

Also, the oximeter ensures accurate measurement readings. In addition, the device is suitable for kids, pregnant women, sports enthusiasts, elderly, hospitals, etc.

Special features of it are:

• A small, lightweight fingertip pulse oximeter
• Low power consumption
• Highly accurate
• LED display
• Convenient to carry

Tips for correct Readings

While using an Oximeter, it is very important to know a few basics so that, you can get accurate results. According to WHO, these few points are:

• While using the device, make sure that the probe is neither too tight or too loose
• Nail paint or Henna on the finger can alter the reading
• Ensure that there is no bright light falling on the probe
• Make minimum movement during the measurement.

Make sure to consult a healthcare professional before using a Pulse Oximeter online, to know the full extent of its use.
