Positive Airway Pressure and Lung Edema
The litterature dealing with the events which follow after induction of positive airway pressure is vast and — sometimes, bewildering. Mead and Whittenberger1 in their chapter on “Lung inflation and hemodynamics” in Handbook of Physiology pointed out that articles on this subject commonly include the phrase “this controversial field,” in the first paragraph. Since that was written our knowledge and understanding of the effect of positive airway pressure on general hemodynamics (venous return, total O2 transport) has increased considerably. The effects on lung edema, however, still remain to be clarified.
