AbstractIt was possible to reach agreement on several important issues relating to VF. First, the phenomenon of CO2 retention may have both pathophysiologic and compensatory components. There is increased awareness of the nature, intensity, and significance of the cross-talk between the ventilatory control center and the pump itself, as expressed in breathing pattern and indices of ventilatory drive. We are learning to interpret that information more effectively to assess functional reserve. Second, knowledge concerning the relative importance of various muscle groups is still incomplete, and the impact of disease on muscle function, lung mechanics, and ventilatory control is not fully understood. Dynamic hyperinflation and sleep disturbances provide two clear examples of conditions whose wide-ranging influence on drive, workload, and muscle function was, until quite recently, under appreciated. Finally, there was a general consensus that our therapeutic approaches to VF should be modified to reflect improved understanding of the pathogenesis of CO2 retention and iatrogenic lung injury. In the acute setting, measures to limit alveolar distention, such as controlling airway pressure, revising blood gas targets, and/or using adjunctive methods for blood gas exchange may avoid barotraumatic edema and rupture. The potential for non-invasive ventilation to avert intubation, facilitate ventilator withdrawal, and help patients with chronic VF to achieve compensation without machine dependence is now being actively investigated. This two day conference proved a stimulating forum for interchange of ideas regarding the state of the field, and allowed many opportunities for scientific interaction, both during outside the formal program.(ABSTRACT TRUNCATED AT 250 WORDS)
