Capnography is a powerful field assessment tool for EMS providers. It is useful on intubated and conscious patients, and important as a prehospital triage and treatment guiding tool. Capnography greatly assists EMS providers develop, monitor and modify patient care plans, by providing immediate breath-to-breath information about the patient's respiratory status. Capnography offers a quantitative numerical reading and graphic waveform that measures, illustrates and documents a patient’s exhaled CO2 at the point in the respiratory cycle in which CO2 is highest (i.e., EtCO2). An elevated EtCO2 level is typically an indication of hypoventilation or increased metabolic activity. A low exhaled CO2 level may be an indication of hyperventilation, decreased cardiac output or poor pulmonary perfusion, which can occur in shock. The "normal" capnography waveform has a specific shape and can be differentiated from "abnormal" capnography waveforms. This course will provide the learner with basic information about respiratory anatomy and physiology, the principles of capnography and capnographic waveforms.
