with mod connection and minor corridor finishing completed in the field. The first units were recently shipped to a site for a healthcare provider on the East Coast, where the foundation had been prepared and the site utilities installed. Once the modules arrived, they were lifted into place and connected in less than two hours. Key Attributes While the STAAT Mod is prefabricated, the solution promotes better clinical outcomes and protects staff and patients when isolation and/or higher level of clinical quality is needed. Key attributes include: • Airborne Infection Isolation Room (AIIR) solution that meets CDC recom- mends for aerosol generating procedures. • Highly engineered for hospital-quality environments designed from a “kit of parts” to be manufactured and assembled quickly. • Expert tested by lean process engineers, critical care nurse trained in COVID-19 protocols, and hospital environment specialist in infection control using a virtual reality platform. • Ability to be configured for multiple applications, from rooms inside other structures (assembly hall, convention center), attached to hospital infrastruc- ture, or a self-sufficient, free-standing deployed hospital that can be placed anywhere. Room Features
HVAC Systems The key attribute of the STAAT Mod HVAC system is that it provides negatively pressurized patient rooms with high air changes rates of HEPA filtered air, providing an Airborne Infectious Isolation room environment to promote patient recovery and staff safely. The HVAC system accomplishes this by exhausting approximately 80 cfm per room, pulling air into the patient room (or the ward), in order to pro- tect staff in adjacent work areas outside the room. The HVAC system incorporates an airflow design featuring HEPA filtration of the recir- culated air, MERV 14 filtration of the supply air, and air distribution designed so that supply air passes past staff toward the patient, where it is exhausted through a low wall grille, capturing as many particles as possible. Plumbing Systems Medical gas systems consisting of medical air, medical vacuum, and oxygen are provided, with outlets incorporated into the patient room headwall and the systems fully piped for distribution. Each tier can be connected to a site’s medical gas infrastructure, or a separate C-Can, containing a medical air compressor, medical vacuum pump, and a manifolded oxygen tank system can be provided. Similarly, each unit is equipped with proper handwashing facilities, and with the plumbing fixtures needed to provide for patient and staff care. Domestic cold water is piped between units, and electric water heaters are provided. The plumbing fixtures all drain via a gravity sanitary waste system, which can be connected to the site utilities or a holding tank for periodic removal. The sanitary waste system runs under the floor through the structural supports and is heat traced as needed. Electrical Systems The power distribution system for the STAAT Mod consists of a nor- mal (utility) source and an essential systems (generator) source and is based upon a 480V distribution. The power is separated into normal, life safety, critical, and equipment branch sources compliant with NFPA 70 requirements. The primary distribution is in a stand-alone primary power module and the generator is provided on a separate skid with additional fuel storage. The primary distribution scheme is scalable to a three-tier configuration by adjusting breaker settings, increasing primary cabling, addressing the size of the generator, and adding additional distribution equipment to sustain each tier. Each tier has distribution equipment to sustain the power, lighting, systems, and mechanical requirements for that tier. Receptacles are designed to meet FGI guidelines and the lighting design meets the intent of IES illumination requirements. Each unit identifies circuits serving the unit to assist in the modular construction. Each tier has a dedicated IT room furnished with two racks. The low voltage systems meet the intent of the FGI guidelines and are designed with a complete fire alarm system. Each module is technology ready with boxes, raceways, and a pathway to designated location above room door. Cabling and terminations will be completed at the device and in the IT closet. The nurse call system will meet the intent of the FGI guidelines and will create a complete patient communications system. Monitoring of engineering systems is provided to the IT room for integration into Owner furnished equipment.
The features of the Airborne Infection Isolation Room (AIIR) are driven by evidence-based design research that have been proven to increase staff and patient safety and improve clinical out- comes. AIIR features include: • Donning station in alcove allows for hand washing prior to donning PPE equip- ment and entering room. • Doffing zone allows removal and dis- posal of contaminated PPE, with hand wash prior to entering clean corridor. • Fixed medical gasses provide access to ventilators, cardiac and vital monitoring, and respiratory treatment at the headwall. • The 15-foot wide room orientation pro- vides adequate space for safe bed trans- fers and portable chest x-ray, and room for a recliner to improve healing • Mobile carts with medical supplies for direct patient care and patient charting. • Viewing window into patient room from the corridor. • Exterior windows to reduce staff stress, improve staff well-being, and increase job satisfaction. Engineering Solutions Due to the contagious nature of the Coronavirus and other potential com- municative diseases, the engineering systems play a crucial role in maintain- ing patient and staff safety.
