Abstract: A cooling appartus for a low air loss therapy bed includes a portable self-contained cooling unit for generating a flow of cool air and a flexible conduit connected to the cooling unit for routing the flow of cool air from the cooling unit. The cooling apparatus also includes an adapter releasably connected to the intake manifold of the bed and having a shroud for allowing passage of a flow of ambient air to the inlet of the manifold and second means coupled to conduit for communicating the flow cool air from said conduit to the inlet without obstructing ambient air flow to the inlet.
