2. Why Monitor Gases? Standards
Equipment status monitor
Patient status monitor
3. What gases are monitored? Oxygen
Carbon dioxide
Nitrous oxide
Nitrogen
Anesthetic agent
Inspired Concentration
Expired Concentration
6. Oxygen Analyzer
7. What other O2 monitors are used?
8. Agent Analyzers
9. End-tidal CO2 Production
Mobilization
Elimination
10. Capnometer ventilation must be sufficient to carry oxygen into the lungs
oxygen is being transported to the mitochondria (CV function)
aerobic metabolism is consuming this oxygen and producing CO2
CO2 is being transported to the lungs (CV function)
CO2 in the expired air gives an indication of adequate ventilation
