ObjectiveTo assess the ability of end-tidal capnography to provide continuous ventilatory monitoring in sedated, non-intubated ED patients following sedative overdose.MethodsObservational study undertaken in a tertiary hospital ED. Patient ventilation was assessed using capnography over 60 min.ResultsCapnography provided uninterrupted monitoring for 99% of total study time. Capnography detected all episodes of hypoxia detected by SpO2 monitoring. Changes in capnography preceded 70% of hypoxic episodes detected by SpO2 . There were no major adverse events or incidents of device failure.ConclusionCapnography provided reliable measurement of ventilatory function in sedated non-intubated, poisoned ED patients.© 2019 Australasian College for Emergency Medicine.
