Finger Oxygen Testers - How to Get Accurate Readings

1. Finger Oxygen Testers - How to Get Accurate Readings Using a finger oxygen tester is an easy way to check the oxygen level in your blood. However, you may be wondering how to make sure that you're getting the best reading possible. Fortunately, there are some simple steps you can take to get the most accurate results. First, it's important to clean the pulse oximeter before use. The lights on the device are sensitive to light, so if you use a dirty finger, the results could be inaccurate. You should also try not to use a cold finger to take the reading. You could have a higher reading if you use a warm finger. If you have a nail polish on your finger, it could also interfere with the results. Another factor that could affect your SpO2 reading is your skin color. Having darker skin could make it harder to measure the blood oxygen. Similarly, if you have a large number of false nails, it could also interfere with the results. You may also have to take them off if you want to get an accurate reading. You can also check the oxygen level of your blood by checking it in your ear. The earlobe contains the same amount of oxygen as blood that comes from the artery. However, this method is only applicable to people who aren't very sick. If you have a medical condition, it's best to stick with a finger oxygen tester. You can also measure your blood oxygen levels while you sleep. If you have a pulse oximeter, you can use it to keep track of your oxygen levels during sleep. You can do this in your bed or at home, but you should check the device with a healthcare provider before you start using it. You should also make sure to report any changes to your provider. If you don't have a pulse oximeter at home, you may be able to get oxygen levels checked at an urgent care center or at your doctor's office. You may also be able to get a prescription pulse oximeter. These devices are designed to be used by doctors, and they go through FDA testing to make sure they're safe for use. You can also check the oxygen level with a smartphone app. These apps use different technology to measure oxygen saturation. However, it's important to note that they're not FDA-approved, and are not intended for professional medical use. Rather, they're marketed as a fun and easy way to measure your oxygen levels. Some even claim to be able to measure oxygen levels in your blood. However, the studies have found that these apps are not very accurate. While there's no proof that using a finger oxygen tester is the best way to measure your oxygen level, it's always better to get a good reading. You may have to try a few different positions, but if you stick to the manufacturer's instructions, you should get an accurate reading.
