What constitutes evidence of proper ET tube placement when using a CO2 detector?

Explanation:
Using a CO2 detector to verify endotracheal tube placement relies on detecting exhaled carbon dioxide. When the tube is in the trachea, exhaled air contains CO2 that the detector picks up, giving a positive CO2 signal (often shown as a color change or a capnography waveform). This confirms the tube is in the airway rather than the esophagus, where little to no CO2 would be detected. Simply attaching the detector without using it provides no information, and waiting for multiple breaths before seeing CO2 would delay confirmation. So, a positive CO2 indication in exhaled air is the best evidence that the tube is in the trachea.
