Measuring blood oxygen levels is crucial, particularly for patients affected by COVID-19, as the disease can lower oxygen levels in the blood, especially if the lungs are affected. Regular monitoring of blood oxygen levels is essential for patients undergoing treatment. Here’s a guide on how to measure blood oxygen levels using a fingertip pulse oximeter:
- Understanding the Device: A fingertip pulse oximeter is designed to calculate the amount of oxygen in the blood. It’s a simple and effective tool for measuring oxygen levels in the body.
- Normal Oxygen Levels: In a healthy individual, the normal oxygen level in the blood ranges from 94 to 98 percent. Levels below 94 percent may indicate potential health issues.
- Using the Device: Ensure the patient is seated or lying down calmly in a suitable environment. Avoid measuring oxygen levels immediately after strenuous activities. Place the patient’s finger on the pulse oximeter and ensure their hand is still and calm on a flat surface for accurate readings.
- Removing Barriers: Ensure there are no barriers between the finger and the device, such as fake nails, artificial nails, henna, tattoos, or nail polish. These can interfere with accurate measurements.
- Interpreting Readings: Once the device is in place, it will display numbers indicating the oxygen level and heart rate. If the oxygen level is below 92 percent, the patient should seek medical attention promptly.
- Alternative Measurement Points: If the patient has obstructions on their finger, such as nail polish, you can use other points like the earlobe, toe, or nose for measurement.
- Seeking Medical Attention: Patients with oxygen levels below 92 percent should be taken to a medical center for further evaluation and treatment. In situations where hospital capacity is limited, home oxygen devices can be used as a temporary measure.
Oxygen is essential for the body’s cells and tissues to function properly. Any decrease in oxygen levels can lead to energy deficiency and pose serious health risks, especially for individuals with conditions like asthma, pulmonary embolism, and cardiovascular problems. COVID-19 can exacerbate this issue by damaging the lungs and further reducing oxygen levels in the body. Regular monitoring of blood oxygen levels is crucial for managing and treating such conditions.
