Ask a question


This medical term refers to the position of a person lying down horizontally. There are several types of decubitus, among them lateral decubitus, ventral decubitus (procubitus), and dorsal decubitus. Certain positions can be used to treat an affliction. For example, head-up decubitus corresponds to a horizontal position in which the head of the patient is higher than the rest of the body. This decubitus has an effect on blood pressure, and is recommended in cases of respiratory difficulties or cerebral edema.
