Summary The shrouding of anaesthetic expiratory valves prevents the anaesthetist from either seeing valve disc movement or hearing clearly the escape of gas during expiration. A modification to one type of valve (Medishield II) is described which replaces this lost information by providing a direct indication of valve opening.
