Oximeter through the detector or sensor, without the need to take blood can be real-time monitoring of the oxygen content of the blood in the body, is a measurement of the human body oxygen saturation, pulse rate, perfusion index and other indicators of the small medical devices.
The oximeter can be used to monitor the body's oxygen saturation, detect whether a patient's lungs have been injured by the new coronavirus, which affects the ability to deliver oxygen to the bloodstream, and play an important role in alerting patients to find a doctor, reducing the likelihood of complications, and evaluating a patient's recovery.
Preliminary judgment of oxygen saturation monitoring by oximeter:
1. Blood oxygen saturation is 95%-100%, which is within the normal range.
2, blood oxygen saturation at 91%-94%, you can seek medical advice.
3, blood oxygen saturation decreased to 90% and below, need to immediately seek medical treatment or call 120.
Note when using:
1. In a calm state, let the finger to keep warm, relax, pinch the finger to wait for the value to stabilize and then release.
2. Do not keep long nails, wear artificial nails or wear nail polish, otherwise it will affect the measurement results.
3. Please clean the dirt from your nails before use, the probe needs to be kept clean.
4. Do not measure blood pressure and oxygen saturation at the same time with the same arm and fingers, otherwise the arm blood pressure belt will block the blood flow, resulting in failure to measure oxygen saturation.
5. Should not be used on fingers with gray nails.
