Quizplus · Accepted Answer

Mechanical ventilators can be powered by electricity from the main power supply or from a backup power source such as a battery. Pneumatic power sources can also be used to compress gas to deliver it to the patient. Hydraulic power sources involve the use of pressurized fluid to create mechanical motion, but this is less commonly used in mechanical ventilation. Magnetic power sources are not typically used in mechanical ventilation. Therefore, options I and II are correct.
