How to Check Your Oxygen Levels at Home: A Comprehensive Guide

Welcome to the first edition of Mega Medical Pulse, our LinkedIn newsletter series.

In this edition, we’re diving into an essential topic: How to Check Your Oxygen Levels at Home: A Comprehensive Guide.

Monitoring your oxygen level at home is essential, especially for individuals with respiratory conditions, those undergoing oxygen therapy, or when recovering from certain illnesses.

With advancements in medical technology, checking your oxygen levels at home has become more accessible than ever. In this guide, we’ll explore everything you need to know about how to check your oxygen level at home, with a focus on pulse oximetry which is widely used for this purpose.

Enjoy the read!

What is Oxygen Saturation and Why is it Important?

Oxygen saturation refers to the percentage of oxygen carried by the red blood cells in your bloodstream. Maintaining an adequate level of oxygen in your blood is crucial to ensure proper functioning of your vital organs. Oxygen levels dropping can indicate health issues, particularly if you experience symptoms such as fatigue or shortness of breath.

When oxygen levels fall below normal, it can lead to complications that often require medical attention such as hypoxemia. For this reason, regularly checking your oxygen level at home is a good practice for long-term health management, especially for those dealing with chronic conditions.

What is Pulse Oximetry?

Pulse oximetry is a non-invasive method to measure blood oxygen levels that is both simple and reliable. A pulse oximeter is a small device typically placed on the fingertip, that estimates the amount of oxygen in your blood using light beams. It also measures your heart rate, which makes it a versatile tool for monitoring both your body’s oxygen levels and your heart’s pulse rate.

This method is commonly used in hospitals, clinics, and increasingly in homes. These devices provide instant feedback which helps in early detection of oxygen level fluctuations, and enables timely intervention if needed.

How to Check Your Oxygen Level at Home with a Pulse Oximeter

The most common and effective way to check your oxygen level at home is using a fingertip pulse oximeter. For most models, you simply need to follow these simple steps:

1. Prepare the Device: Press the power button to turn on the pulse oximeter Ensure that the battery is sufficiently charged for accurate readings.
2. Place the Sensor: Attach the pulse oximeter to your fingertip and make sure that the sensor is positioned over the nail bed. For people with darker skin tones, the accuracy of the reading may sometimes vary, which makes it very important to properly position the device for precise measurement.
3. Stay Still: Oximeters can be made less accurate by excessive movement. To get a more reliable measurement, make sure you remain still and minimise any shaking in your hand.
4. Wait for the Reading: The pulse oximeter will display your oxygen saturation level (SpO2) and your pulse rate after a few seconds. Healthy oxygen saturation levels normally range between 95% and 100%. We recommend seeking medical attention if your oxygen saturation levels drop below 90%.
5. Record Your Results: Be sure to record your readings in an accessible location. This data can be very helpful for your healthcare provider to assess your oxygen needs and monitor any patterns in your health.

How to Ensure Accurate Readings with a Pulse Oximeter

Pulse oximeters are generally accurate, however many factors can affect their readings. Be sure to keep these things in mind to ensure you get the most reliable measurement:

• Nail Polish or Artificial Nails: Nail polish, especially darker colors, can interfere with light sensor of the pulse oximeter, leading to inaccurate readings. For greater accuracy, remove any nail polish beforehand or avoid using the device on a finger with polish.
• Cold Hands: Poor circulation due to cold hands can affect the reliability of pulse oximeter readings. Be sure to warm your hands before you take a reading to ensure proper blood flow.
• Darker Skin: Individuals with darker skin tones can receive less accurate readings from a pulse oximeter. What is more important in this instance is to compare readings over time to identify trends rather than relying on a single measurement. When in doubt however, please contact your healthcare provider.
• Movement: Even slight movements are able to disrupt the pulse oximeter’s ability to accurately read oxygen levels. It is best practice to sit still and wait for a stable reading before recording the result.
• Proper Placement: Ensure the device is properly placed on the finger, and completely covering the nail bed. Incorrect placement can affect the sensor’s ability to measure oxygen levels accurately, leading to unreliable readings.

When to Check Your Oxygen Level

The frequency that you should check your oxygen level at home depends on your health condition and the recommendations from your healthcare provider. Individuals with respiratory conditions or those receiving oxygen therapy may need to check their oxygen levels several times a day. For other individuals, checking once a day or only when required due to the arisal of symptoms like shortness of breath may be sufficient.

Here are a few scenarios when monitoring your oxygen level might be important:

• Before and After Physical Activity: Physical exertion can impact oxygen levels, which can be exacerbated for those with lung conditions. It’s important to check your oxygen level before and after exercise to assess your body’s tolerance and the amount of oxygen in your blood.
• When Experiencing Symptoms of Breathlessness: When experiencing shortness of breath, fatigue, or dizziness, checking your oxygen level is vital so you can see if your symptoms are related to low oxygen saturation.
• When Undergoing Oxygen Therapy: If you’re receiving oxygen therapy at home from a concentrator or cylinder, you may need to check your levels more frequently to ensure you’re receiving the right amount of oxygen.

What Do the Numbers Mean?

When checking your oxygen level at home, it’s important to understand what the numbers on the pulse oximeter actually represent:

• Normal Range: Oxygen saturation levels between 95% and 100% are considered normal for most healthy individuals.
• Mild Hypoxemia: Oxygen levels between 90% and 94% may indicate mild hypoxemia, which could require closer monitoring or adjustment to your oxygen therapy.
• Severe Hypoxemia: Levels below 90% are a cause for concern and may require immediate medical attention.

If you find that your oxygen saturation consistently falls below normal levels, and if you also experience symptoms such as chest pain or shortness of breath, seek medical attention right away.

If your healthcare provider ends up recommending oxygen therapy to manage your oxygen levels, you may require an oxygen concentrator as a practical and affordable solution. If you are looking for oxygen concentrator, Mega Medical has a wide range of options to rent or buy to suit your needs.

Conclusion

Knowing how to check your oxygen level at home is essential, especially for those with underlying respiratory issues or those undergoing oxygen therapy. Pulse oximetry is a quick, reliable, and non-invasive way to monitor your blood oxygen level and heart rate. However, it’s important to use the device correctly and understand the factors that may affect its accuracy. By staying informed and keeping track of your oxygen levels, you can take proactive steps to maintain your health and seek medical attention when necessary.
