A simple, safe and efficient anaesthetic breathing system for universal use in rural environments.
A new simple, safe and efficient anaesthetic breathing system, the Humphrey ADE system, is described for universal use on adults and children. Specialist knowledge is not required as it has been designed to be easy to use. Requiring low fresh gas flows of only three to four litres per minute, the system is efficient for spontaneous, manually assisted respiration, and for controlled ventilation with an automatic ventilator. These multiple functions are dependent on only two positions of a single lever. Easy to follow instructions are permanently engraved on the main block.
