Chapter 033. Dyspnea and Pulmonary Edema (Part 4)

Approach to the Patient: Dyspnea (Fig. 33-3) In obtaining a history, the patient should be asked to describe in his/her own words what the discomfort feels like, as well as the effect of position, infections, and environmental stimuli on the dyspnea. Orthopnea is a common indicator of congestive heart failure, mechanical impairment of the diaphragm associated with obesity, or asthma triggered by esophageal reflux. Nocturnal dyspnea suggests congestive heart failure or asthma. Acute, intermittent episodes of dyspnea are more likely to reflect episodes of myocardial ischemia, bronchospasm, or pulmonary embolism, while chronic persistent dyspnea is typical of COPD and. | Chapter 033.

Orthopnea is a common indicator of congestive heart failure mechanical impairment of the diaphragm associated with obesity or asthma triggered by esophageal reflux. Nocturnal dyspnea suggests congestive heart failure or asthma. Acute intermittent episodes of dyspnea are more likely to reflect episodes of myocardial ischemia bronchospasm or pulmonary embolism while chronic persistent dyspnea is typical of COPD and interstitial lung disease. Risk factors for occupational lung disease and for coronary artery disease should be solicited. Left atrial myxoma or hepatopulmonary syndrome should be considered when the patient complains of platypnea defined as dyspnea in the upright position with relief in the supine position.
