  • Page 14: Principles Of Operation

    3900/3900P User’s Manual Principles of operation The 3900/3900P pulse oximeter uses a two-wavelength pulsatile system—red and infrared light—to distinguish between oxygenated (O Hb) and reduced (HHb) hemoglobin, each of which absorbs different amounts of light emitted from the oximeter sensor. The system then calculates the relative percentage of these two constituents and displays SpO Variable absorption (due to arterial pulse)

  • Page 15: Calibration

    1/Overview is “on” and the oxygenation of the arterial hemoglobin. Analog and digital signal processing then converts the light-intensity information into SpO , pulse rate, and pulsatile values for display on the monitor. Calibration A CO-oximeter typically uses four or more wavelengths of light and calculates reduced hemoglobin (HHb), oxyhemoglobin (O Hb), carboxyhemoglobin (COHb), and methemoglobin (MetHb).
