One morning she felt severely fatigued and saw that her oxygen level had dropped to 88 percent. Chang, an associate professor of emergency medicine and director of clinical research for Thomas Jefferson University, even started feeling better but kept up her daily monitoring with her pulse oximeter. Anna Marie Chang, an emergency room physician in Philadelphia, tested positive for coronavirus in mid-March, she felt lousy but was reassured by daily checks that showed normal oxygen levels. The good news is that it’s a lot easier to bolster an oxygen level that is just starting to drop than one that is dangerously low. If your number dips to 92 or lower, you should check in with your doctor. What happens if my oxygen level falls? What is the treatment? Very long nails would make it difficult to insert your finger properly in the clip. Dark nail polish can affect accuracy of the reading. Do long nails or nail polish make a difference?

For that reason, patients with darker skin should consider checking in with their doctors if the reading drop to 93 or 94. In cases of inaccurate monitoring, the device typically overstates oxygen levels by about 2 points. The potential for error is the reason patients should monitor themselves frequently and pay attention to the overall trend of declining oxygen levels. An analysis, of 10,789 paired test results from 1,333 white patients and 276 Black patients hospitalized at the University of Michigan earlier this year, found that pulse oximetry overestimated oxygen levels 3.6 percent of the time in white patients, but got it wrong nearly 12 percent of the time, or more than three times more often, in Black patients. Researchers suspect that sometimes the devices may give inaccurate readings because of the way the light is absorbed by darker skin pigments. The difference between fingers is small, so if you prefer the index finger, that’s fine. If you are left-handed, use the left middle finger. So if you are right-handed, use the right middle finger. Most health technicians will place the device on the index fingers, but a study of 37 volunteers found that the highest reading came from the third finger on the dominant hand. If you’ve been to a doctor in the past 20 years, you’ve experienced pulse oximetry.

Your pulse oximeter will give you a numerical reading - a percentage that indicates the level of oxygen saturation in your blood. Hemoglobin absorbs different amounts and wavelengths of light depending on the level of oxygen it’s carrying. It’s targeting hemoglobin, a protein molecule in your blood that carries oxygen. When you insert your finger into a pulse oximeter, it beams different wavelengths of light through your finger (you won’t feel a thing). (It was 98.) How does a pulse oximeter work? The first time I tried my home device, it looked like my oxygen level was an alarming 86, but then I realized I was reading it upside down.

Pro tip: One of the things to remember about reading a pulse oximeter is that many of them are designed to be read by someone facing you, not the person wearing it. A normal resting heart rate for adults ranges from about 60 to 100 beats per minute, although athletes with a higher cardiovascular fitness will have a lower pulse. The device will also show your heart rate. You should check in with your doctor if the number falls to around 93 or 92 or lower. Some people with existing health conditions may have a lower normal reading. Most healthy people will get an oxygen reading around 95 to 98 percent. You place your finger snugly inside (most require nail side up), and within seconds it lights up with numbers indicating your blood oxygen level and heart rate. A pulse oximeter is a small device that looks sort of like a chip clip or a big clothes pin.
