Turnkey Operating Theatre

The operating theatre department is a complex area in the hospital, and significant challenges are encountered in the co-ordination of M&E services such as HVAC and medical gas plumbing during constructions or renovations. At the same time, the planning of an operating theatre department of a hospital requires a detailed understanding of staff work flows and patientsí movement. Only then, the design can be certain of having the best possible floor-layout and an optimal working environment for the hospital staff, the highest levels of staff and patient safety, and savings on operating-costs over time.

Johnson Medical Surgical Unit generally includes medical pendants, ceiling fixture, ventilation system, operating lights, operating table and various medical equipment support systems depending on the application. The Johnson Medical pendants are patented, and based on customersí requirement for the number of gas outlets and electrical points.
