Capno-ROSC
Capnogram Patterns & Return of Spontaneous Circulation
Investigating whether capnogram-derived airway patterns are associated with ROSC in out-of-hospital cardiac arrest.
The Problem
Effective ventilation during CPR is essential for gas exchange, but excessive or inadequate ventilation may impair outcomes. Intrathoracic airway closure and thoracic distension alter the capnogram waveform, but their impact on ROSC is unknown.
Our Approach
Retrospective analysis of prehospital capnogram data from Urgences-santé to identify waveform patterns (airway closure, thoracic distension) and their association with ROSC.
Innovation
First systematic evaluation of capnogram-derived ventilation phenotypes and their real-world impact on resuscitation outcomes in the prehospital setting.
