1. An aspirator comprising:
a vacuum pump for producing a vacuum pressure; a motor for driving the vacuum pump; a manifold configured to direct a flow of gas from an upstream side in communication with a patient to a downstream side in communication with the pump; a valve in communication with the manifold, the valve being configured to control vacuum characteristics across the manifold; a sensor in communication with the manifold, the sensor being configured to sense vacuum pressure across the manifold; a barometer configured to sense ambient atmospheric pressure; a processor in communication with the motor and the valve; and wherein the processor is configured to control the motor and/or the valve in response to a signal received from the sensor and/or the barometer.
