Embodiments of a reduced pressure system and methods for operating the system are disclosed. In some embodiments, the system can include one or more processors responsible for various functions associated with various levels of responsiveness, such as interfacing with a user, controlling a vacuum pump, providing network connectivity, etc. The system can present GUI screens for controlling and monitoring its operation. The system can be configured to determine and monitor flow of fluid in the system by utilizing one or more of the following: monitoring the speed of a pump motor, monitoring flow of fluid in a portion of a fluid flow path by using a calibrated fluid flow restrictor, and monitoring one or more characteristics of the pressure pulses. The system can be configured to provide external connectivity for accomplishing various activities, such as location tracking of the system, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.
