The present specification discloses a ventilator system that can be manufactured quickly with minimal skill requirements and rapidly deployed in response to epidemic respiratory disease conditions. In one embodiment, the ventilator, having a minimal number of controls, is used to give ventilation or mechanical breathing to a patient suffering ARDS. The mechanical ventilation is based on pressure control and has variable pressure, breathing rate, and oxygenation. Preferably, the ventilator is rapidly deployable, easy and intuitive to operate, and capable of sustaining at least 75% of epidemic respiratory distress victims who require assisted ventilation until resuming normal breathing.
