Pulmonary mattress

A patient support surface comprising:

• a cover defining an enclosed interior region, the interior region comprising;
• a layer of three dimensional material, the three-dimensional material including a network of thermoplastic fibers;
• an air circulation device disposed adjacent the layer of three dimensional material;
• and
• a hose defining a channel within the interior region, the hose having a first end and a second end spaced from the first end,
• a first connector adjacent the cover and adapted to couple the first end of the hose to a first external device and a second connector spaced from the first connector adjacent the cover and adapted to couple the second end of the hose to a second external device.

A patient support surface comprising:

• a support surface including a cover defining an enclosed interior region, the interior region comprising:
• a layer of three dimensional material, the three-dimensional material including a network of thermoplastic fibers, a first blower disposed adjacent the layer of three dimensional material, a second blower spaced apart from the first blower;
• at least one of a percussion and a vibration device, and
• a plurality of bolsters adjacent a perimeter of the patient support surface, the bolsters being arranged to support the first blower and the second blower,
• wherein the first blower and second blower are configured to direct air through the layer of three dimensional material.

A patient support surface having a head end including a pair of lateral sides and a foot end comprising:

• a cover defining an interior region;
• a layer of three dimensional material, located in the interior region, the three-dimensional material including a network of thermoplastic fibers;
• an air circulation device disposed adjacent the layer of three dimensional material;
• a head elevation device, located in the interior region at the head end of the patient support surface, the head elevation device including a support surface having a plurality of hinge points to alternatingly laterally elevate the lateral sides of the head end of the patient support surface;
• a head of bed indicator configured to indicate when predetermined angles of head elevation are reached;
• and
• at least one of a percussion device and a vibration device, located at the interior region.
