fluid filtration rates ( ffr 's , the change in lung weight/time ) in response to a 7.5-min zone 3 hydrostatic stress ( pulmonary arterial and venous pressures raised from 8 to 15 cmh2o , alveolar pressure kept constant at 4 cm on the deflation limb ) were repeatedly measured for 120 min after which the lungs were lavaged .
