Summary: 
Respiratory model based on a Starling resistor for the collapsible upper airway. a) When critical pressure (Pcrit) is lower than zero there is no airway collapse and the breathing pattern is normal, as shown in the normal flow and oesophageal pressure (Poes). b) When Pcrit is positive this results in an airway closure, apnoea, inducing a progressive decrease in intratracheal pressure (Ptr) as the patient tries to breathe against a collapsed airway. c) When Pcrit is slightly negative the upper airway partially collapses and a hypopnoea occurs as the Ptr progressively decreases along with inspiration. Pn: upstream (nasal) pressure. #: -4 cmH2O; ¶: -30 cmH2O.
