The provided standard specification details a robust medical gas delivery system with a strong focus on patient safety and operational efficiency. This system features a non-metallic, water-resistant, and fire-retardant moulded body constructed from high-quality engineering-grade polymer. Key components include a back-lit illuminated 2-gas, cascaded 4-tube Rotameter and a Selectatech bar designed for precise control of agent-specific vaporizers. It incorporates a self-sealing inlet for piped gas, a master switch for system control, and a common gas outlet for easy operation. The system also includes integrated power backup, electrical extension outlets, and a microprocessor-based pneumatic ventilator. Patient safety is paramount, with features like a gear-linked mechanical hypoxic control device, fresh gas compensation to prevent volutrauma, and nitrous oxide interlocking. It also includes alarms for oxygen pressure, airway pressure, minute volume, and FiO2 levels, ensuring the highest standards of care during medical procedures
