1. A method of determining a blockage in a negative pressure wound therapy system, the method comprising, by a controller:
receiving first pressure data indicative of a combined pressure in a plurality of fluid flow paths fluidically connecting a negative pressure source with a plurality of wound dressings, wherein the plurality of fluid flow paths comprises at least a first fluid flow path including a first valve and a second fluid flow path including a second valve;
based on a determination that the first pressure data satisfies a first blockage threshold, determining that the plurality of fluid flow paths includes a fluid flow path associated with a blockage condition; and
based at least in part on a second pressure data, identifying at least one fluid flow path of the plurality of fluid flow paths that is associated with the blockage condition, wherein the second pressure data is obtained when at least one of the first valve or the second valve is closed.
