Claim 19:
20. A wound therapy device comprising:
a battery;
a pump configured to be worn by a user; and
a controller coupled to the pump and configured to operate the pump in one of at least four operating modes, wherein a first operating mode of the at least four operating modes is associated with a first drive voltage, wherein a second operating mode of the at least four operating modes is associated with a second drive voltage and a first duty cycle range of the pump, the second drive voltage less than the first drive voltage, and wherein a third operating mode of the at least four operating modes is associated with a second duty cycle range of the pump, the second duty cycle range different from the first duty cycle range, wherein
the third operating mode delivers a first therapeutic amount of pressure from the pump, the first therapeutic amount of pressure being less than a second therapeutic amount of pressure delivered by the pump in the second operating mode,
a fourth operating mode of the at least four operating modes delivers a third therapeutic amount of pressure from the pump, the third therapeutic amount of pressure being less than the second therapeutic amount of pressure delivered by the pump in the second operating mode, the fourth operating mode being activated in response to a battery level of the battery failing to satisfy a battery threshold,
the fourth operating mode is associated with a third drive voltage that is less than the second drive voltage; and

the first therapeutic amount of pressure, the second therapeutic amount of pressure, and the third therapeutic amount of pressure are non-zero amounts of pressure.
