WebNov 28, 2024 · Sudden decrease or loss of end-tidal CO2 suggests a drastic decrease in cardiac output due to gas embolism. Continuous pulmonary arterial pressure can be used to evaluate for gas embolism. … WebNormal end-tidal CO2 values are 35-45 mmHg. This phase is also called a descending phase because oxygen fills when inhalation begins and CO2 concentration decreases. ... WebEnd tidal carbon dioxide tension (P(ET,CO(2))) is a surrogate for dead space ventilation which may be useful in the evaluation of pulmonary embolism (PE). We aimed to define the optimal P(ET,CO(2)) level to exclude PE in patients evaluated for possible thromboembolism. 298 patients were enrolled over 6 months at a single academic centre. swlc conference
