Conclusion: Fingernail polish does not cause a clinically significant change in pulse oximeter readings in healthy people.
Background: Pulse oximeter is a simple and noninvasive standard device to monitor the saturation of peripheral oxygen (SpO2) and heart rate. The nail polish of different colors may result in inaccurate oximetry reading and interpretation of oxygen saturation.
Generally What are three conditions that can give a false pulse oximetry reading? Be aware that multiple factors can affect the accuracy of a pulse oximeter reading, such as poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and use of fingernail polish.

Frequently Asked Questions(FAQ)
Can I polish my nails while on oxygen?
Summary: When a patient is admitted to hospital, one of the first clinical actions is to measure the concentration of oxygen in the blood by using a pulse oximeter positioned along the length of the nail. To prevent any possible interference, any nail varnish is removed.
Does long nails affect pulse oximeter readings?
Nail treatments do not affect readings of patients’ oxygen levels, despite widespread concern, according to researchers from Ireland.
Which finger is best for pulse oximeter?
middle finger Which finger to use in a pulse oximeter? As per the studies, your right hand’s middle finger shows the best results. Make sure to take off any nail polish and avoid using on cold fingers as the readings may not show correctly.
How much does acrylic nails affect pulse oximeter readings?
The mean pulse oximetry reading at baseline was 97.33% and after acrylic nail application, 97.58%. Using a paired Student’s t test, no statistically significant differences existed between readings. This study demonstrates that unpolished acrylic nails do not affect pulse oximetry measurements of oxygen saturation.
Is 97 a good oxygen level?
If you do have a pulse oximeter and are checking your oxygen levels, it’s important to know that a level between 95 and 97% is considered normal by the American Lung Association; anything below that would be a reason to call a doctor, and anything under 90% would be a reason to go to the emergency room.
How accurate are finger pulse oximeters?
Prescription oximeters typically have an accuracy rate within 4% above or below the reading. In other words, if your oxygen level is 92%, it could actually be as low as 88% or as high as 96%.
What is low oxygen level for Covid?
You should start oxygen therapy on any COVID-19 patient with an oxygen saturation below 90 percent, even if they show no physical signs of a low oxygen level. If the patient has any warning signs of low oxygen levels, start oxygen therapy immediately.
How can I increase my blood oxygen level?
Breathing in fresh air: Opening your windows or going outside for a walk can increase the amount of oxygen that your body brings in, which increases your overall blood oxygen level. Quitting smoking: Only two to three weeks after you quit smoking, your circulation will likely improve significantly.
What causes low oxygen in Covid?
Their research, which has been published in Nature Communications, reveals that silent hypoxia is likely caused by a combination of biological mechanisms that may occur simultaneously in the lungs of COVID-19 patients, according to biomedical engineer Jacob Herrmann, a research postdoctoral associate in Suki’s lab and
What is a healthy oxygen level?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The SpO2 reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
Will a pulse ox read through acrylic nails?
Summary: New research suggests that nail treatments such as acrylic nails or nail polishes do not, as previously thought, affect readings from digital pulse oximetry (DPO) devices used to monitor patients’ blood oxygen saturation (SpO2) levels in hospital.
What are the symptoms of low oxygen levels?
Low blood oxygen levels can result in abnormal circulation and cause the following symptoms:
- shortness of breath.
- headaches.
- restlessness.
- dizziness.
- rapid breathing.
- chest pain.
- confusion.
- high blood pressure.
