What are three conditions that can give a false pulse oximetry reading?
Recommendations for Health Care Providers 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.

Does a pulse oximeter work with gel nails?
They are of two different wavelengths.It passes a beam of light and detects oxygen levels. If you’ve applied nail polish or anything else, it interferes with the passing of the beam through the pulse oximeter to your nail bed. That is why we are not able to get the right readings.”

Does nail thickness affect pulse oximetry?
“Can the oxygen in the blood be measured if the nails have been painted? Study indicates that the slight alteration in a pulse oximeter reading caused by nail varnish is clinically irrelevant.” ScienceDaily. ScienceDaily, 30 November 2015.

What is the most common source of error and false alarms with pulse oximetry quizlet?
Common factors causing false LOW readings when using a pulse oximeter include: 1) presence of moderate levels of metHb (actual SaO2 > 85%), 2) anemia in the presence of significant hypoxemia (actual SaO2< 70%), and 3) most vascular dyes (e.g., methylene blue).

What causes false low oxygen saturation?
Digital pulse oximetry is a rapid noninvasive test and is used to estimate arterial oxygen saturation. However, falsely low readings are common due to a range of causes including motion artifact, hypotension, nail polish, darker skin pigmentation, and venous pulsations.

Can you use a pulse oximeter with gel nails?
CONCLUSION. Gel-based manicures can result in overestimations of actual readings, delaying detection of hypoxaemia. Gel nail polish should be routinely removed or an alternative monitoring technique sought.

Can a pulse oximeter read through gel polish?
Nail polish or nail varnish can impact pulse oximeter accuracy, so it is best to remove the polish to allow the light from the probe to pass through the tissue.

What color nail polish interferes with pulse oximeter?
Black, blue, and green nail polish significantly lowered oximeter readings of oxygen saturation. Blue and green produced greater decreases than purple and red; black produced an intermediate decrease. Some but not all nail polishes absorbed light at the wavelengths used by the pulse oximeter (660 nm and 940 nm).

Which may cause false low readings in pulse oximetry?
Factors that can produce falsely low estimates of arterial hemoglobin saturation by pulse oximetry (SaO 2) include the presence of methemoglobin (1) anemia combined with hypotension (2,3) motion (4), dark skin pigmentation including certain skin dyes (5), blue or green fingernail polish (6), and severe tricuspid …

Why nail polish must be removed when checking pulse oximeter?
The sensors of the pulse oximeter are usually fitted to the fingernails, where nail varnish could distort the measurement. That is why during the clinical examination in an emergency situation, nail varnish is routinely removed to assess oxygen saturation.
