Now consider
what would happen if you took a patient with acute bronchoconstriction
and dyspnea and placed him on a mechanical ventilator with positive
pressure ventilation.
Question

of chest tightness be reduced by positive pressure ventilation?
Many patients with asthma and COPD complain of a sense of "an

sensation of an unsatisfied breath likely arise?
