Baseline characteristics by cohort
Measure	Esophageal Then Tracheal Intubated Patient n=11 Participants Esophagus is intentionally intubated with a cuffed endotracheal tube, the cuff inflated to \>30cm water pressure, a force transducer attached, and force of extubation recorded. Then Trachea is intentionally intubated the cuff inflated to \>30cm water pressure, and force of extubation recorded. Measuring extubation force: Intubation of the esophagus of anesthetized participants who are having planned endotracheal intubate for surgery; inflation of the cuff; attachment of a force transducer to the tube connector; and gently tugging the tube out of the mouth. Then intubating the esophagus and repeating the tugging procedure. Meanwhile, the force of resistance to tugging is measured with a force transducer.
