Pulmonary oedema with acute asthma
Pulmonary oedema with acute asthma is a rare non cardiogenic cause of pulmonary oedema.
Associated trapped air tends to maintain a positive intraalveolar pressure, thus decreasing the hydrostatic pressure gradient. Its pathogenesis can be associated with the severity of the Müller maneuver (ie, forced inspiration as the patient struggles to inhale) 1.
