Final answer:
To know if a pulse oximeter is working properly, follow these steps: ensure it is turned on and functioning correctly, place the sensor correctly, check the readings within the normal range, compare the readings with another reliable source if possible, and observe the patient for any abnormalities.
Step-by-step explanation:
A pulse oximeter is a device that measures the oxygen saturation level in the blood. To ensure that a pulse oximeter is working properly, you can follow these steps:
- Make sure the device is turned on and functioning correctly.
- Place the sensor on a thin part of the body, such as the finger or earlobe.
- Ensure that the sensor is secure and not loose or slipping.
- Check that the device displays readings within the normal range of 95-100 percent saturation.
- If possible, compare the readings from the pulse oximeter with another reliable source, such as an arterial blood gas test.
- Observe the patient for any signs of discomfort or abnormal readings, and consult a healthcare professional if necessary.
By following these steps, you can determine if the pulse oximeter is working properly and providing accurate oxygen saturation readings.
