One or more embodiments of the presently described invention provides a ventilator including a timing device, an electric power source and a flow control device. The timing device is electronically controlled and is capable of controlling a period of time that a fluid is delivered to a patient. The timing device can control this period of time using a solenoid. The flow control device controls a rate of flow that the fluid is delivered to the patient. The flow control device can control the rate of flow using a plurality of orifices. The timing device and flow control device are separate from one another and each is capable of being operated independent of the other. |
