Answer

The use of mechanical ventilation during the polio epidemics of the 1950s was the impetus that led to the development of the discipline of critical care medicine. Before the mid-1950s, negative-pressure ventilation with the use of iron lungs was the predominant method of ventilatory support. Currently, virtually all mechanical ventilatory support for acute respiratory failure is provided by positive-pressure ventilation. Nevertheless, negative-pressure ventilation still is used occasionally in patients with chronic respiratory failure.
