General description The 3800, 3900, and 3900P pulse oximeters are noninvasive, arterial oxygen saturation and pulse rate monitors. Through the use of a sensor applied to the patient and connected to the monitor, these pulse oximeters measure the absorption of selected wavelengths of light to calculate pulse rate and arterial oxygen saturation. The light generated in the sensor passes through the tissue and is converted into an electronic signal by a photodetector in the sensor. The electronic signal passes to the oximeter and is amplified. Analog and digital signal processing convert the light intensity information into SpO2 and pulse rate values. Both models feature two easy-to-read displays that present patient data and status information. The numeric LEDs (light-emitting diodes) show the SpO2 and pulse rate values. The LCD (liquid crystal display) shows alarm messages, the plethysmographic waveform (or data), and the high and low SpO 2 and pulse rate limit settings. This display also shows the Relative Perfusion Index (PIr®) pulsatile value and menus as appropriate for the monitor.
