Background Cardiac implantable electric devices are commonly used to treat heart failure. Little is known about temporal and geographic variation in use of cardiac resynchronization therapy (CRT) devices in usual care settings.
A hammer drill, also known as a rotary hammer, roto-drill or hammering drill, (see also rotary drill) is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort.
A roto kinetic bed is used for pts with spinal or multiple traumas.This bed maintains skeletal alignment while providing constant rotation. It works by providing a constant side-to-side rotation 60 degrees up to 90 degrees q 7 mins.
