We executed this critical milestone by establishing a temporary, localized manifold system with high-capacity gas cylinders directly inside the ICU to bypass the main line. The actual pipe cutting, brazing, and tie-in of the main network were rehearsed extensively and executed during a carefully coordinated, meticulously planned 15-minute maintenance window at 3:00 AM, utilizing HEPA-filtered containment tents to maintain absolute sterility.

The most nerve-wracking phase was the requirement to tie the newly installed medical gas lines directly into the hospital’s existing, active network. We had to perform this delicate integration without shutting down or jeopardizing the gas supply to the patients currently on ventilators in the adjacent cardiovascular intensive care unit.
