摘要：
A method and system assist a physician in controlling pressure in a line during a surgery. The method includes filtering a vacuum signal such that portions of the vacuum signal having a frequency greater than a threshold frequency (e.g., ten Hz) are not passed. Thus a filtered vacuum signal is provided. The method also includes providing a control signal to a vacuum source. The control signal is selected from the vacuum signal and the filtered vacuum signal. The vacuum source provides a vacuum having a level based on the control signal.
