Letter to the Editor
After reading the article on managing acute pulmonary oedema,1 I would like to point out the following. Pulmonary embolus causes pulmonary ischaemia not oedema. Nitrates do not cause coronary vasodilatation as they are already maximally dilated by way of autoregulation. Morphine causes coronary vasoconstriction in conscious dogs.2
