Pulzoximéter: A Guide to Measuring Blood Oxygen Saturation
What is a Pulzoximeter?
A pulse oximeter is a medical device that measures the oxygen saturation of your blood. It is a small, clip-like device that is placed on your finger, toe, or earlobe. The device uses light to measure the amount of oxygen in your blood. Pulse oximeters are used to monitor oxygen levels in people with respiratory problems, such as asthma or COPD. They can also be used to monitor oxygen levels in people who are undergoing surgery or who are recovering from an illness.
How Does a Pulzoximeter Work?
A pulse oximeter works by shining light through your finger, toe, or earlobe. The light is absorbed by the hemoglobin in your blood. Hemoglobin is the protein in red blood cells that carries oxygen. The amount of light that is absorbed depends on how much oxygen is in your blood. The pulse oximeter measures the amount of light that is absorbed and uses this information to calculate your blood oxygen saturation. Blood oxygen saturation is the percentage of oxygen-carrying hemoglobin in your blood. A normal blood oxygen saturation level is between 95% and 100%.
Why is it Important to Measure Blood Oxygen Saturation?
Blood oxygen saturation is an important measure of your overall health. Low blood oxygen saturation levels can indicate a number of health problems, including: * Respiratory problems, such as asthma or COPD * Heart problems, such as congestive heart failure * Anemia * Shock * Sepsis Measuring blood oxygen saturation can help your doctor diagnose and treat these conditions.
How to Use a Pulzoximeter
Using a pulse oximeter is simple. Follow these steps: 1. Wash your hands and the site where you will be placing the pulse oximeter. 2. Turn on the pulse oximeter. 3. Place the pulse oximeter on your finger, toe, or earlobe. 4. Make sure that the pulse oximeter is snug but not too tight. 5. Wait for the pulse oximeter to read your blood oxygen saturation. The pulse oximeter will display your blood oxygen saturation level on a screen. You should record your blood oxygen saturation level and the time of day that you took the reading.
What to Do if Your Blood Oxygen Saturation Level is Low
If your blood oxygen saturation level is below 95%, you should see your doctor. Low blood oxygen saturation levels can indicate a number of health problems. Your doctor will perform tests to determine the cause of your low blood oxygen saturation level and recommend treatment.
