A ventilator apparatus includes a linear electro-mechanical actuator that interfaces with a self-inflating bag including an inlet configured to receive air and an outlet configured to expend the air. A three-way valve is coupled to the outlet via a first flowmeter, an ambient environment via a second flowmeter, and a patient via an endotracheal tube. The first and/or second flowmeters are coupled to pressure transducer(s). A control unit is coupled to the linear electro-mechanical actuator and the first and second flowmeters and includes a control panel, memory including programmed instructions stored thereon, and processor(s) configured to execute the stored programmed instructions to set an inhalation time and an exhalation time. A current inspiratory pressure and a current tidal volume are obtained from the pressure transducer(s) and/or the first flowmeter. A stroke of the linear electro-mechanical actuator is then controlled to facilitate inspiratory and expiratory phases of a respiratory cycle.
