Cardiology A modality for ↓ preload in acute cardiogenic pulmonary edema, in which the blood flow to the extremities is blocked by RTs; because preload is ↓ more precisely with nitroprusside, RTs are rarely used

rotating tourniquet

The application of blood pressure cuffs to three extremities; formerly used in certain types of medical emergencies, such as acute pulmonary edema, to reduce the return of blood to the heart. The patient is placed in a head-high position (Fowler's). The pressure is kept midway between systolic and diastolic. Every 10 min, the cuffs are deflated and when inflated, the previously free extremity is now used. This allows each extremity to be free of a tourniquet for 10 min out of each 40-min cycle.

Note

A cuff would not be applied to an extremity into which an intravenous infusion is running.
