End-tidal CO2 after CO2 embolism

Utility of Prehospital Quantitative End Tidal CO2?

INTRODUCTION End tidal CO2 (ETCO2) has been established as a standard for confirmation of an airway, but its role is expanding. In certain settings ETCO2 closely approximates the partial pressure of arterial CO2 (PaCO2) and has been described as a tool to optimize a patient's ventilatory status. ETCO2 monitors are increasingly being used by EMS personnel to guide ventilation in the prehospital ...

Bedside end-tidal CO2 tension as a screening tool to exclude pulmonary embolism.

End 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. P(ET,CO(2)) was measured within 24 h of contrast-enhanced...

End-tidal CO2 for exclusion of suspected pulmonary embolism: a new partner for Wells?

The diagnosis of PE remains a challenge because of highly variable clinical symptoms. Consequently, the diagnosis of PE has been finally confirmed in ,35% of patients with a clinical suspicion of PE [3]. A simple bedside test with the ability to exclude PE in patients who do not have it, while not overlooking true-positive cases, is desired and will prevent unnecessary exposure to contrast agen...
