About Glostavent® Helix Duo

An addition to the renowned Glostavent anaesthesia range, the Glostavent® Helix Duo incorporates the same key characteristics of the Glostavent® Helix with the additional advantage of two, low resistance, draw over vaporisers. The twin vaporisers permit the safe delivery of a gaseous induction using Sevoflurane before switching to the more cost-effective Isoflurane to maintain the anaesthetised state. The vaporiser switching mechanism incorporates a ‘break before make’ safety feature to permit seamless and controlled changeover between both vaporisers, with no possibility of having both units in use in the circuit simultaneously.

The Glostavent® Helix Duo is designed to function when power or oxygen fail in the operating theatre. The machine produces its own oxygen and medical air, has backup power and built-in mechanical ventilators, making it perfect for low resource environments.
