Previously reported changes in static lung volumes during pregnancy have been confirmed. Measurements of lung compliance (C(L)) and total pulmonary resistance (R(L)) were made in 10 women in the last trimester of pregnancy and 2 months postpartum, employing an esophageal balloon and recording spirometer. C(L) was unaffected by pregnancy, but R(L) was 50% below normal during pregnancy. Measurements of airway conductance (C(A)) were made, employing the constant pressure body plethysmograph on 14… CONTINUE READING
