  2. Introduction • Capnography: the vital sign of ventilation • Innovative technology • Growing recognition of safety advantages • Continuous real time measurement • More accurate than traditional methods

  3. Physiology of Capnography • End of respiration • CO2-free gases • V/Q ratio • Respiratory dead space • CO2 curve

  4. Methods for Measuring CO2 • Mainstream • Sidestream • Infrared measurement

  5. Definitions • Capnography • Capnometer • Capnogram

  6. Oxygenation vs. Ventilation • Oxygenation • Gas exchange • Ventilation

  7. Capnography vs. Pulse Oximetry
