What is a ‘transport ventilator’?

The term transport ventilator can refer to a wide range of ventilators in terms of capability. Generally, the term ‘transport’ refers to the capability to use the ventilator for transporting patients during which time central power and pressurized gas supply may be limited. These ventilators usually have robust internal battery backups and the ability to function without a high pressure gas supply (e.g. they include a turbine or compressor to entrain room air to drive the ventilator). Most can also operate with either high or low pressure oxygen input. Many transport ventilators are designed to care for intensive care unit patients (See WHO Technical Specifications for Ventilators).
