Variable air volume. Variable Air Volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant temperature.
A ventricular assist device (VAD), also known as a heart pump, is a mechanical device that helps pump blood from the heart to the rest of your body. A VAD can be implanted in the chest or worn outside the body. If it is implanted, surgery is done to place it in the chest area. The pump part of the VAD is placed in a small space in your upper abdomen.
