Connectors are commonly used in anesthesia circuitry to establish functional continuity between various components. The Bain's system is widely accepted as a universal breathing system with the ability to connect to a ventilator for mechanical ventilation during anesthesia. [1] It can be attached to the ventilator hose connection via special 22-mm female to female connector. A conventional adult anesthesia facemask has a 22-mm internal diameter female connector end to accommodate 22-mm male fitting components from machine end. It can act as a two-way connector by connecting the 22-mm adjustable pressure limiting valve of the Bain's circuit to the 22-mm male ventilator hose connection fitting of anesthesia ventilator [Figure 1]. This assembly can be of utility for administering anesthesia in peripheral locations where anesthesia machines usually are not equipped with built-in ventilators as in newer workstations. A soft malleable mask apart from assisting ventilation can be used as a replacement for 22-mm female connectors for two 22-mm male ends.
