Abstract: A treatment system includes a vaporizer, a tent for maintaining a high humidity environment in a chamber around at least the upper body of an individual under treatment, and a flexible conduit from the vaporizer to the chamber. The tent includes a supporting framework and a porous fabric supported by the framework. The fabric, preferably a polyester tricot, consists of multifilament strands woven to provide a porosity of about fifty percent. So constructed, the fabric is air permeable, yet tends to block a substantial percentage of moisture droplets suspended in the air, thereby increasing the relative humidity inside the therapy tent to a value substantially above ambient relative humidity, for example over ninety percent while ambient levels outside the tent remain at about fifty percent. As a result, a therapeutic, high humidity environment is maintained about the patient, without the need for oxygen supplies, pumps, blowers or other special equipment.

Abstract: A controller for self-refilling resuscitation enclosures has a pair of arms pivotable between open and closed positions, an inside strap fixed to both arms, and an outside strap fixed to one arm. The outer strap can be releasably coupled at any one of a series of locations along the other arm, to selectively limit the amount of resuscitation bag recovery and thereby adjustably control the expansion or recovery volume of the enclosure. The straps, along with portions of the arm inside surfaces, maintain a contiguous wrapping engagement about the resuscitation enclosure throughout its compression and expansion, to positively secure the enclosure. The arms afford a mechanical advantage to reduce user fatigue, and provide for the tactile sensing of lung compliance during resuscitation.
