1. A medical aspirator for providing suction to a patient, comprising:
a manifold having a fluid inlet in fluid communication with the patient and a fluid outlet;
a valve in fluid communication with the manifold and being operable to control vacuum characteristics between the fluid inlet and fluid outlet;
a vacuum pump motor having a pump head in fluid communication with the fluid outlet of the manifold and configured to provide the suction for the patient; and
a processor in communication with the vacuum pump motor and the valve and configured to control the vacuum pump motor and/or the valve to generate vacuum pressure between the fluid inlet and the fluid outlet and gas flow through the manifold in accordance with a selected one of a plurality of user-selectable operational modes comprising a plurality of continuous operation modes, each corresponding to a respective medical use of a plurality of medical uses, and at least one pre-programmed vacuum pressure level associated with each respective medical use of the plurality of medical uses, the plurality of user-selectable operational modes further comprising an intermittent operation mode.
