What Causes Facet Syndrome? Facet syndrome is generally the result of the natural aging process. However, the initial cause of arthritis, or facet syndrome, may also be an injury or overuse of the joints in youth. Another possible cause of facet disease is spondylolisthesis, which is when one vertebra â usually in the lumbar spine â slips forward over the lower vertebrae. When the facet joints become inflamed due to injury or age, the result is stiffness and pain.
An energy recovery ventilator (ERV) is a type of mechanical equipment that features a heat exchanger combined with a ventilation system for providing controlled ventilation into a building.
A Ventilator (also called a Respirator) is a machine that helps a person breathe. 1  A person who has sustained a brain injury may be unable to breathe on his or her own.To use a ventilator, a tube is placed through the personâs mouth to the breathing passage, (trachea, âwindpipeâ). 2  This procedure is called intubation.
