Home ventilators are often small and portable. Most types can be attached to wheelchairs. They can also be set up by the bed for use when sleeping.
A ventilator works by pushing air (and extra oxygen, if needed) into the lungs. Common ways to deliver the air are through a tracheostomy (trach) tube or tightly fitted face mask. If a trach tube is used, it is placed through a small hole (stoma) in the front of the neck and directly into the windpipe. If a mask is used, it is fitted over the nose, mouth, or both. The trach tube or mask is then connected to the ventilator.
Ventilators can deliver different types of breaths, such as volume control and volume assist, pressure control and pressure assist, and pressure support. Some people need to use the ventilator all of the time. Others may only need it at certain times, such as when sleeping.
