Which CO2 test is best for emergency breathing tube checks?
NCT ID NCT06934876
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two methods—waveform capnography and a color-changing carbon dioxide detector—to see which more accurately confirms that a breathing tube is in the right place (the windpipe) in critically ill adults. About 2,000 patients in emergency departments or intensive care units will be enrolled. The goal is to find out which test is more sensitive and specific, helping doctors make safer decisions during intubation.
