Pulse oximeter technical specifications define performance, accuracy, and features, including SpO2/Pulse Rate ranges (e.g., 0-100% SpO2, 20-250 BPM), accuracy (e.g., ±2-3% SpO2, ±3 BPM HR), display type (LED/LCD with plethysmograph), power (batteries/AC), alarms, and environmental resilience (shock/vibration), all crucial for medical use. Key parameters focus on measuring arterial oxygen saturation (SpO2) and heart rate (HR), with accuracy varying by conditions like low perfusion or dark skin.
To use a pulse oximeter, ensure your hand is warm and still, clip the device to a clean finger (no polish/false nails) below heart level, wait for steady readings (SpO2 % and pulse rate), and record the numbers once stable, remembering normal SpO2 is usually 95-100%. For accuracy, rest quietly for 5 minutes before, avoid movement, and use a middle or index finger.
