Relationship Between Critical Pressure and Volume Exhaled During Negative Pressure in Awake Subjects With Sleep-Disordered Breathing

In males with neck circumference > 37 cm, V,NEP0.5 during wakefulness strongly reflects Pcrit in a wide range of values. Our findings suggest that V,NEP0.5 can be used as valuable substitute for Pcrit to assess UA collapsibility for clinical and research purposes in these subjects.
