ch 15 what points on a capnographic waveform represens a misture of alveolar gas and dead space gas

Part 2, Introduction to Capnography, relates this information to the phases of ventilation and introduces common waveform patterns.

Capnography provides objective information on your patient’s ventilation status similar to the heart rate and ECG waveform on the cardiac system.
