Measuring the rate of forced exhalation is used to diagnose obstructive lung diseases because O the positive pressure that exists during exhalation causes the airways to open fully and allows more ready movement of air into the lungs the negative pressure which occurs in the lungs during exhalation unmasks airway problems the positive pressure that exists during exhalation causes the airways to collapse which accentuates underlying airway problems O the negative pressure in the lungs during exhalation will pull airways open and mask airway problems
