Can you give examples of findings you may come across when obtaining pulse oximetry measurements and the implications of these findings?

When obtaining pulse oximetry measurements, you may encounter findings such as hypoxemia, indicated by oxygen saturation levels below 90%, which can suggest respiratory or cardiovascular issues requiring immediate intervention. Additionally, readings that are falsely elevated due to factors like carbon monoxide exposure or nail polish can lead to misdiagnosis and inappropriate treatment. Variability in readings may also indicate poor peripheral perfusion, necessitating further assessment of the patient's circulatory status. These findings underscore the importance of correlating pulse oximetry results with clinical assessment and additional diagnostic tests.
