This is accomplished with either negative (subatmospheric) or positive pressure administered via an external interface. Mechanical ventilation emerged first with negative pressure ventilation in 1830, predating the development of artificial airways. It had a long history of success in treating polio patients in respiratory failure. The concept of body ventilation later evolved to include positive pressure ventilation delivered via external masks covering some combination of the nose and mouth.
