An integrated and modular air and lighting plenum that is the primary directional lighting mounting apparatus and laminar flow diffuser of an HVAC system in a healthcare setting. The plenum provides laminar air flow from the ceiling to the room in which it is located in accordance with HVAC requirements for healthcare environment settings, by using a plurality of cylindrical airflow outlets. The use of cylindrical airflow outlets promotes laminar airflow by reducing sharp boundaries that induce turbulence (e.g., the corners of rectangular or square outlets) and creates a highly sterile environment around the patient and staff in the operating room. The surgical lights used in the integrated air and lighting plenum allow the beam direction, spot size, focal point, brightness, and color temperature of the emitted light to be controlled.

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

Described herein are components, systems, and methods of use of an integrated sterilization system comprising a pass-through logistics cabinet, an ozone sterilization system, a floor sterilization robot, and systems for controlling such components. An integrated operating room sterilization system will allow mitigation or elimination of risks (e.g., infrastructural risks (e.g., OI risks), procedural risks (e.g., risk of infection and contamination) that are associated with a setting in a healthcare environment. The elimination of clutter, control of major components under a unified and intuitive user interface, and the logical elimination of potential accumulated risk events (e.g., OI risks) and procedural risks are deliberately addressed, in whole or in part, by the present disclosure. The present disclosure describes the following: a pass-through logistics cabinet, an ozone sterilization system, a floor sterilization robot, and systems for controlling such components.

An integrated control system for controlling components of a setting of a healthcare environment, the integrated control system including one or more wireless computing devices; one or more displays; a plurality of components of the setting, wherein at least one component of the plurality of components is an ozone sterilization system, an integrated air and lighting plenum, a surgical lighting system, a pass-through logistics cabinet, or a floor sterilization robot; and a server. The server includes a connection for connecting to a remote healthcare environment information system, and a receiver and a transmitter for communicating data between the plurality of components of the setting, medical equipment connected to one of the plurality of components, the remote healthcare environment information system, the one or more wireless computing devices and the one or more displays.
