Pressure-flow signatures of central-airway mucus plugging.
METHODS
Medical Intensive Care Unit of Regions Hospital, a University of Minnesota-affiliated teaching hospital.


METHODS
Mechanically ventilated woman with status asthmaticus and acute respiratory failure.


METHODS
Observations of airway pressure and flow tracings before and after bronchoscopic inspection and airway lavage.


RESULTS
Four newly observed signs were recorded that may serve to identify occult central airway mucus plugging in the ventilated asthmatic patient.
