Introduction
Under normal circumstances, finger pulse oximeters primarily monitor arterial oxygen saturation and pulse rate. The normal range for arterial oxygen saturation is generally 95% to 98%; the normal pulse rate range is 60 to 100 beats per minute. When using a finger pulse oximeter, ensure the finger is warm, clean, and dry, and properly position the sensor to obtain accurate measurement results.
Under normal circumstances, finger pulse oximeters primarily monitor arterial oxygen saturation and pulse rate. The normal range for arterial oxygen saturation is generally 95%-98%; the normal pulse rate range is 60-100 beats per minute. If any abnormalities are detected, timely medical consultation is recommended. Detailed explanations are as follows:
The normal range of oxygen saturation measured by a finger pulse oximeter is typically 95%-98%. This range reflects the degree of oxygen binding to hemoglobin in the blood, indicating sufficient oxygen supply to meet the normal metabolic needs of various organs and tissues in the body. If oxygen saturation falls below the normal range, it may indicate hypoxia, and prompt medical attention with further evaluation and treatment as recommended by a physician is advised.
The normal pulse rate range displayed by a finger pulse oximeter is 60-100 beats per minute. Pulse rate refers to the frequency of arterial pulsations, which reflects, to some extent, the heart's beating rate. Normally, each heartbeat generates one pulse. A pulse rate stably maintained within 60-100 beats per minute indicates normal cardiac pumping function and systemic blood circulation.
When using a finger pulse oximeter, ensure the finger is warm, clean, and dry, and position the sensor correctly to obtain accurate measurement results.
