Pulmonary oedema in chronic bronchitis - a haemodynamic study

Right heart catheterization was performed in ten patients with pulmonary oedema. Mean wedge pressures in excess of 12 mmHg above the mid-axillary line were regarded as abnormal and indicating left heart failure. If the wedge pressure was less than 12 mmHg, and pulmonary congestion was present, frusemide was given. Brief descriptions of the ten cases are given.
