Immediately after securing the airway, you want to document two critical things: exactly how deep the tube sits (lip distance) and exactly how you verified that it’s in the trachea (the verification method). The lip distance gives a repeatable, portable measure of tube depth so you can detect displacement if the patient moves or if care is handed off. Recording the verification method shows precisely how you confirmed placement—such as a capnography waveform, bilateral breath sounds with equal chest rise, and absence of epigastric distension, with radiographic confirmation when available. This combination provides a complete, actionable record for ongoing safety and coordination.

Other options miss one of these essential pieces: documenting only the tube size, only the lip distance, or only the time of intubation does not convey whether the tube is correctly placed or how that placement was confirmed.
