Introduction
Pulse rate measurement using a finger pulse oximeter refers to the method of measuring heart rate and blood oxygen saturation by clamping the device onto a finger. Under normal circumstances, this method is generally accurate when the device is of reliable quality, used correctly, and the subject is in a relatively calm or stable condition. However, if there are issues with the device quality, measurement technique, subject status, or environmental factors, the accuracy of the results may be affected.
Generally, when the device is of reliable quality, used correctly, and the subject is in a relatively calm or stable state, measuring heart rate with a finger clip device is usually accurate. However, if there are issues with the device quality, usage method, subject's condition, or environmental factors, these may also affect the accuracy of the results. A detailed analysis is as follows:
Finger clip heart rate measurement refers to using a finger pulse oximeter to measure heart rate and blood oxygen saturation. In healthy adults or individuals with mild cardiovascular disease, accurate measurements of heart rate and blood oxygen saturation can usually be obtained when the device is properly worn during a resting state.
However, poor device quality or sensor aging, incorrect wearing of the device, finger movement or external interference during measurement, or the subject being in a state of intense physical activity, emotional excitement, or poor physical condition may all affect the accuracy of the measurement results.
Therefore, when using a finger pulse oximeter, it is important to ensure the finger is warm and relaxed, and that the device makes close contact with the skin. The subject should be in a relatively calm or stable condition to minimize measurement errors.
