“…The sensor contains two light-emitting diodes (LEDs) that alternatively emit red (660nm) and infrared light (940nm). Opposite to the diodes, there is a photoreceptor, with the tissue to be examined being placed between the photoreceptor and the LEDs (1,(11)(12)(13).…”

Objective: To evaluate the changes in measurements of pulse oximetry in healthy individuals with nail polish. Methods: Cross sectional study with 80 healthy volunteers. The colors of enamel used to assess oxygen saturation (SpO2) were: coffee with milk, coffee, chocolate, red and plum. These colors were distributed among the finger nails of his left hand. The fingers of the right hand were the controls. Results: The colors red (p = 0.047) and coffee (p = 0.024) showed lower values in SpO2 in comparison to the control. The other colors did not change the measurement of SpO2. Conclusion: The colors red and coffee caused reduction in the measurement of SpO2, but the clinical relevance of this finding is questionable, because the values were within the normal range.

Métodos: Estudo transversal com 80 voluntárias sadias. As cores de esmalte utilizadas para avaliar a saturação periférica de oxigênio (SpO 2 ) foram: café com leite, café, chocolate, vermelho e ameixa. Estas cores foram distribuídas entre as unhas dos dedos da mão esquerda. Os dedos da mão direita foram os controles. Resultados: As cores vermelha (p=0,047) e café (p=0,024) mostraram valores menores na SpO 2 quando comparados ao controle. As outras cores não alteraram a medida da SpO 2 . Conclusão: As cores vermelha e café causaram redução na medida da SpO 2 , porém a relevância clínica deste achado é questionável, pois os valores estavam dentro do intervalo de normalidade.

Métodos: Estudio transversal realizado con 80 voluntarias sanas. Los colores de esmalte utilizados para evaluar la saturación periférica de oxígeno (SpO 2 ) fueron: café con leche, café, chocolate, rojo y ciruela. Estos colores fueron distribuidos entre las uñas de los dedos de la mano izquierda. Los dedos de la mano derecha fueron los controles. Resultados: Los colores rojo (p=0,047) y café (p=0,024) mostraron valores menores en la SpO 2 cuando fueron comparados al control. Los otros colores no alteraron la medida del SpO 2 . Conclusión: Los colores rojo y café causaron reducción en la medida del SpO 2 , sin embargo la relevancia clínica de este hallazgo es cuestionable, pues los valores estaban dentro del intervalo de normalidad.

“…The oxygen-saturated hemoglobin absorbs more infrared light while the desaturated hemoglobin absorbs more red light. A microprocessor calculates the hemoglobin saturation of arterial blood, continuously analyzing the difference between the two components of pulsatile (arterial) and nonpulsatile (venous) light absorption (3,(11)(12)(13).…”
