Which of the following most accurately describe(s) the relationship of lung volume in a restrictive disease and PAW:o I.Increasing PAW increases lung volume and improves ventilation–perfusion matching.o II.Increasing PAW increases the pressure gradient, allowing more oxygen to cross the alveolar capillary membrane.o III.Increasing PAW improves the efficiency of the jet or piston.o IV.At very high and very low lung volumes ventilation–perfusion matching is impaired.
