Cardiogenic asthma is mostly due to acute heart failure, especially acute left heart failure causing respiratory distress. When it occurs, the patient is asked to sit, oxygen is administered, and immediate pharmacological treatment is given: first, morphine is usually given intravenously to sedate and assist in reducing the cardiac load, and then a strong diuretic is quickly administered often, using furosemide intravenously, which can be repeated if necessary. Next, vasodilator therapy, often using sodium nitroprusside or nitroglycerin micro-pump pumping. Again, cardioplegic treatment, especially in patients presenting with atrial fibrillation and increased ventricular rate, is often selected for slow intravenous pushing of cetiran. Finally, the use of aminophylline to calm asthma and positive inotropic effects, dexamethasone or methylprednisolone and other glucocorticoids to improve vascular permeability can also reduce pulmonary edema and relieve chest tightness. Cardiogenic asthma is a critical illness, and drug therapy should be started as early as possible.
