  8. 10. Capnometer <ul><li>ventilation must be sufficient to carry oxygen into the lungs </li></ul><ul><li>oxygen is being transported to the mitochondria (CV function) </li></ul><ul><li>aerobic metabolism is consuming this oxygen and producing CO2 </li></ul><ul><li>CO2 is being transported to the lungs (CV function) </li></ul><ul><li>CO2 in the expired air gives an indication of adequate ventilation </li></ul>What it tells you What it doesn’t tell you Does not tell about regional blood flow, cerebral or cardiac ischemia can occur with normal ET CO2.
