California Pulse Oximeter Warning
Certain studies have indicated that users with darker skin pigmentation and melanin may experience variations in readings that make the oxygen level appear higher than it may be. It is recommended users with these concerns consult their licensed healthcare provider to ensure their most accurate oxygen saturation measurements and establish a baseline value when healthy and at rest.
FDA’s recommendations on how to interpret a reading:
- When taking pulse oximeter measurements, pay attention to whether the oxygen level is lower than earlier measurements, or is decreasing over time. Changes or trends in measurements may be more meaningful than one single measurement.
- Do not rely only on a pulse oximeter to assess your health condition or oxygen level.
- If monitoring oxygen levels at home, pay attention to other signs or symptoms of low oxygen levels, such as:
- Bluish coloring in the face, lips, or nails;
- Shortness of breath, difficulty breathing, or a cough that gets worse;
- Restlessness and discomfort;
- Chest pain or tightness; and
- Fast or racing pulse rate.
- Be aware that some patients with low oxygen levels may not show any or all of these symptoms. Only a health care provider can diagnose a medical condition such as hypoxia (low oxygen levels).
