Treatment of Dyspnea
Treatment is correction of the underlying disorder. 93% if myocardial or cerebral ischemia is a concern, although data suggest that supplemental oxygen is not beneficial in the treatment of acute myocardial infarction unless the patient has hypoxia ( Treatment reference ). Morphine0.5 to 5 mg IV helps reduce anxiety and the discomfort of dyspnea in various conditions, including myocardial infarction, pulmonary embolism, and the dyspnea that commonly accompanies terminal illness. However, opioids can be deleterious in patients with acute airflow limitation (eg, asthma, COPD) because they suppress the ventilatory drive and can worsen respiratory acidemia. 1.Cabello JB, Burls A, Emparanza JI, Bayliss SE, Quinn T.
