Description: Segment 1 The credits roll over shots of Oxford. A voice-over explains the importance of ordinary 'air' as an agent for ventilation over shots of a man asleep and a woman on an artificial respirator. The narrator demonstrates the EMO inhaler which was designed in Oxford. The inhaler works with Oxford inflating bellows, which is briefly shown. The EMO inhaler mixes air with volatile anaesthetic agents (such as ether): the EMO inhaler is shown being prepared with the active agent poured in. A middle-aged woman who requires surgery is shown being anaesthetised: anaesthesia is induced via an injection before the gradual process of achieving adequate anaesthesia via the EMO inhaler is shown. The anaesthetist counts four breaths before increasing the dosage - with full anaesthesia being achieved in 10 minutes. The patient then has an endotrachael tube inserted and this is shown being secured with a bandage. The patient is wheeled away to the operating theatre. A more complex surgical scenario is shown (with more staff around the patient) the advantage of the EMO inhaler is that it can be moved away from the immediate surgical area so that the operation can proceed without the inconvenience of lots of tubing, the requirement to change cylinders and the anaesthetist is then free to monitor the patient.

The next case study shows an elderly male patient requiring a muscle relaxant and shows the process of induction and maintenance of anaesthesia. Time start: 00:06:18:00 Time end: 00:10:32:00 Length: 00:04:14:00 Segment 3 The next case study features a middle-aged male patient who has also been given a muscle relaxant. An infant is seen very briefly having been anaesthetised with artifical ventilation maintained with small bellows as well as a male patient laying on his front with a valve inserted into his throat (a position which is relatively inaccessible to the anaesthetist in a crowded operating theatre). A number of case studies are shown where patients require deeper anaesthesia and agents which induce repressed respiration the anaesthetist provides artifical respiration either by an automated pump or manually. The EMO inhaler is shown functioning throughout. The closing sequences show the equipment being packed away into easily portable cases and a man, presumably the anaesthetist, leaving the hosptial, case in hand, and driving off in his car. The objective of this sequence is to emphasis the portability and convenience of the equipment. Time start: 00:10:32:00 Time end: 00:16:30:15 Length: 00:05:58:15
