End‐tidal capnography provides reliable ventilatory monitoring for non‐intubated patients presenting after sedative overdose to the emergency department

Abstract

Objective: To assess the ability of end-tidal capnography to provide continuous ventilatory monitoring in sedated, non-intubated ED patients following sedative overdose. Methods: Observational study undertaken in a tertiary hospital ED. Patient ventilation was assessed using capnography over 60 min. Results: Capnography provided uninterrupted monitoring for 99% of total study time. Capnography detected all episodes of hypoxia detected by SpO 2 monitoring. Changes in capnography preceded 70% of hypoxic episodes detected by SpO 2 . There were no major adverse events or incidents of device failure. Conclusion: Capnography provided reliable measurement of ventilatory function in sedated non-intubated, poisoned ED patients.

Non-invasive positive pressure ventilation to prevent respiratory complications of severe tetanus- sedation and methodological insights

“…In this case, there could be a potential obstructive or central event ( Contal et al ., 2013 ). From the monitoring point of view, it might be interesting to know if the authors used capnography to monitor endtidal carbon dioxide ( Millane et al ., 2020 ). It would be interesting to know how the authors planned the de-escalation of the NPPV over a while.Further studies and clinical trials are required to confirm the best sedation and methodological approach in such cases of respiratory failure that are managed with NPPV.…”
