A transport ventilator is a ventilator- a device to help people who cannot breathe independently- designed for use in patient transport. In addition, they are used by people who rely on ventilators to breathe and want to enjoy mobility in their communities and while traveling. These devices are manufactured by a number of medical supply companies, along with accessories. People using transport ventilators at home receive detailed instruction in their use so they can adjust their ventilator settings, reset their ventilators, and perform basic maintenance.

Ventilators are designed to deliver an oxygen and air mix to a patient, with the concentration of the mix being adjustable. The volume and frequency can be controlled with adjustment. Some ventilator designs permit patients to breathe independently while on a ventilator, while others take over for the patient's respiratory system entirely. The design suitable for a patient varies, depending on the patient's condition and needs.

Transport ventilators are designed with mobility in mind. They have an independent power source so they are not tethered to a wall outlet, and they are more compact than standard ventilators. The transport ventilator is also usually very sturdy, encased in a solid housing designed to withstand the shock of being dropped, compressed, or stepped on. This keeps the ventilator functional even under less than optimal conditions.
