- Title
CrossTalk opposing view: The human upper airway during sleep does not behave like a Starling resistor.

- Abstract
The authors discuss the phenomenon of flow limitation during Starling resistor application in the airway. They refutes the notion that the upper airway exhibits pressure-flow dynamics during sleep that are comparable to those in a Starling resistor. The assertion is supported by experimental data in which a subject with sleep apnea exhibited maximum airflow that decreases in epiglottic pressure. A model of the tongue subjected to negative intrapharyngeal pressures during inspiration is offered.
