Postural variations in pulmonary edema and embolism

Hey Awesomites

Patients with pulmonary edema prefer to be in an upright position, while those with pulmonary embolism prefer flat position.

This is because in cases of edema, there is excess fluid accumulation in lungs, which limits respiratory movements. In upright position, the fluid will settle down and thus it lowers the pressure in pulmonary vessels which makes it easier to breathe.

On the other hand, in case of pulmonary embolism, the patient  is placed in left lateral decubitus (durant maneouver) and Trendelenburg position immediately. The air embolus moves through the right side of heart to enter into the lungs. But in Durant's maneouvre and Trendelenburg position, the embolus gets trapped in the apex of the heart and so does not get transported through pulm arteries to enter the lungs.
