In today's world, maintaining a healthy body is essential to prevent unwanted health issues. Although the COVID-19 virus is less prevalent, it remains important to monitor our health, particularly by measuring oxygen levels in the body. One effective tool for this purpose is the pulse oximeter.

What is a Pulse Oximeter?

A pulse oximeter is a medical device used to measure the level of oxygen in the blood and heart rate. This device can quickly detect changes in blood oxygen levels using advanced technology, providing valuable information to help monitor your health. Several conditions can cause decreased oxygen levels in the blood, including asthma, pneumonia, heart failure, anemia, asphyxia, respiratory failure, and obstructive pulmonary disease.

How Does a Pulse Oximeter Work?

The pulse oximeter operates by shining light through the fingertip and measuring the amount of oxygen in the blood based on how the light passes through the finger. This small, portable device features a screen that displays the percentage of oxygen in the blood. In addition to measuring oxygen levels, a pulse oximeter can also assess pulse rate.

How to Use a Pulse Oximeter

Using a pulse oximeter is quite simple. Most models are designed as clips that fit onto a finger. To use it, follow these steps:

1. Clean Your Fingers:: Wash your hands to ensure they are free from dirt. Make sure your nails are clean and trimmed, avoiding dark nail polish or artificial nails.
2. Warm Your FingersIf your fingers are cold, warm them up before using the device.
3. Insert Your Finger: Turn on the oximeter and insert your finger into the clip, positioning it properly.
4. Wait for the Reading: Allow the oximeter to evaluate your blood for a few seconds until it displays the results on the screen.
5. Wash Your Hands: After using the oximeter, wash your hands again.

Understanding the Readings on the Oximeter

The display of a pulse oximeter shows two key numbers, each with a different meaning. The percentage of oxygen saturation in the blood is indicated by %SpO2, while the heart rate is marked with HR (heart rate). Normal oxygen levels are generally 95% or higher. If the %SpO2 reading falls below 92%, it indicates oxygen deprivation, which requires immediate medical attention. It's important to note that a pulse oximeter does not measure carbon dioxide levels.

If you experience symptoms of decreased oxygen levels, such as shortness of breath, asthma, pale skin, weakness, or bluish lips and nails, seek medical assistance promptly.

A decrease in oxygen levels can occur suddenly and in various situations. Therefore, it’s crucial to regularly check your blood oxygen levels with a pulse oximeter to ensure your health and well-being.
