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.

Can nail polish affect oximeter?
Certain colors of nail polish may lead to underestimation of SaO2 by pulse oximetry. Studies have shown that in healthy adults, blue, green, black, and brown nail polish appear to interfere the most with pulse oximeter SpO2 readings. In fact, they can cause readings of up to a 3-5% underestimation in oxygen saturation.

Which Colour of nail polish does not affect SpO2?
Nail polish colors, orange, pink, and purple did not have an effect on SpO2, while the other colors did provide a statistical difference (p<0.05). These readings however were clinically insignificant with <1.2%.

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.
