When using the pulse oximeter as part of your assessment of a patient it is important to remember that?

When using a pulse oximeter, it's important to remember that factors such as poor circulation, skin pigmentation, and nail polish can affect its accuracy. Additionally, the device measures only oxygen saturation (SpO2) and does not provide information about carbon dioxide levels or overall respiratory function. Ensure the sensor is placed correctly and consider the patient's clinical context when interpreting the results. Always corroborate pulse oximeter readings with other clinical assessments.
