Reversible nasal airway obstruction: does change in nasal peak inspiratory flow following decongestion predict response to topical steroids in chronic rhinosinusitis patients?
The difference between pre- and post-decongestion nasal peak inspiratory flow does not predict chronic rhinosinusitis patients' response to topical steroids.
The main findings are as follows: (a) PEEP effectively decreases EVLW. (b) The decrease in EVLW is closely correlated with the PEEP-induced decrease in nonaerated lung volume, making EVLW a valuable bedside parameter indicating alveolar recruitment, similar to measurements of transpulmonary shunt. (c) As excess tissue volume remained constant, however, EVLW may not be suitable to reflect overall severity of lung disease
