Abstract
Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly and a wound dressing configured to be positioned over a wound. The pump assembly and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound via a fluid flow path. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of conditions, such as a blockage in a fluid flow path. Monitoring of the conditions can be performed by detecting a level of activity of a pump of the pump assembly.
