Handheld ultrasound as an adjunct to physical examination in the diagnosis of cardiopulmonary disease.

Abstract

Handheld 2D ultrasound devices (HUDs) have become available as an adjunct to physical examinations, visualizing the heart and lungs in real time and facilitating prompt patient diagnosis and treatment of cardiopulmonar.y disorders. These devices provide simple and rapid bedside alternatives to repetitive chest x-rays, standard ultrasound examinations and thoracic CT scans. Two currently available HUDs are described. This paper discusses the use of HUDs in the diagnosis of patients with pericardial effusion and tamponade, ventricular dilation, aortic and mitral regurgitation, cardiogenic pulmonary edema, viral and bacterial pneumonia, pleural effusion and pneumothorax. The use of a HUD by physicians increases clinical diagnostic accuracy, adds quantitative information about cardiopulmonary disease severity and guides the use of medications and interventions.
