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.
