Реферат: A gas pressure monitor system for a pneumatically-powered surgical machine includes a first transducer, a second transducer, and a controller. The first transducer is located upstream from a filter and is configured to read a first pressure of a gas before the gas enters the filter. The second transducer is located downstream from the Filter and is configured to read a second pressure of a gas after the gas exits the filter. The controller is configured to compute a difference between the first pressure and the second pressure. A state of the filter is determined from the difference between the first pressure and the second pressure.
