Double T-piece, an injector, and Bird ventilator use in MRI suite

The double T-piece breathing system is described. The Bird Ventilator Mark 2 is utilised as an oxygen pressure jet to drive an injector placed at the distal end of the double T-piece breathing system. An active anti-pollution assembly is employed. Both the double T-piece breathing system and the anti-pollution assembly are valveless. The injector's design is described. The ventilator functioned properly at 1.8 m distance from 1.5 tesla electromagnet without degrading its imaging. The Bird ventilator, the injector, and the double T-piece breathing system are small in size, easy to handle, and can be used for paediatric and adult patients.
