1. A wound treatment system, comprising:
a housing;
a processor that is located in the housing;
at least one sensor system that is coupled to the processor, wherein the at least one sensor system comprises a humidity sensor;
a power delivery system that is located in the housing and that is coupled to the processor;
an oxygen concentrator that is located in the housing and that is coupled to the power delivery system, wherein the oxygen concentrator includes an oxygen outlet that is coupled to a restricted airflow enclosure that is provided by a dressing and that is located adjacent a wound site; and
a negative pressure system that is coupled to the processor, wherein the negative pressure system includes a negative pressure outlet that is coupled to the restricted airflow enclosure that is provided by the dressing and that is located adjacent the wound site;
wherein the processor is configured to:
receive first sensor information from the at least one sensor system, wherein the first sensor information comprises atmospheric humidity information;
use the first sensor information comprising the atmospheric humidity information to control the power provided from the power delivery system to the oxygen concentrator in order to control an oxygen flow created by the oxygen concentrator and provided through the oxygen outlet to the restricted airflow enclosure;
receive second sensor information from the at least one sensor system; and
activate the negative pressure system to create a fluid flow from the restricted airflow enclosure and through the negative pressure outlet.
