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.

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.

Esophagus

Withdrawal Force.

Esophagus, then trachea, are intentionally intubated with a cuffed endotracheal tube, the cuff inflated to >30cm water pressure, a force transducer attached, and force of extubation recorded.

Overall Study

Dr. William P. McKay

Intubation, Intratracheal

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.

Force of Endotracheal Tube Extubation; Esophagus vs. Trachea

Force of Endotracheal Tube Extubation; Esophagus vs. Trachea; an Exploratory Crossover Clinical Trial

Our intubation studies have generated a large database of tracheal length measurements that, with this study added, should probably be published separately.
