Abstract:
In embodiments of the present invention improved capabilities are described for evaluating pulmonary embolism. A system and method of evaluating pulmonary embolism in a subject may include measuring end tidal partial pressure of exhaled carbon dioxide in the subject, wherein the measurement is made orally, obtaining a clinical approximation of dead space ventilation based on the measurement, and excluding pulmonary embolism when the end tidal partial pressure of exhaled carbon dioxide reaches a threshold.
