The programme is in two parts: The first part includes a demonstration of simulated high altitude decompression at the Institute of Aviation, Farnborough. The subject, Squadron Leader Denison, beco...mes hypoxic, eventually unconscious and then recovers. Dr Denison then goes on to discuss the reasons for this behaviour of the system and the difficulties of modelling it. The second part of the programme consists of a demonstration of the use of a mathematical model as a teaching device. The computer presents imaginery patients to which the students, by means of a standard keyboard, can give various treatments. Behaviour of a broncho-pneumonia patient when given 100% oxygen is displayed (eventual death) and a second patient with periodic breathing, is treated with a carbon dioxide mixture.

Footage description: Shots of two pilots undergoing simulated high altitude decompression at the Institute of Aviation Medicine, Farnborough. Commentary by Beishon. D M Dennison explains what the simulated high altitude decompression tests are trying to discover. Shots of D M Dennison in decompression chamber. Commentary by Beishon explains the experimental set-up. Shots of the decompression test. Voice of Dennison explains each phase. Dennison loses consciousness due to hypoxia, then recovers. Dennison explains reasons for subjects undergoing mental ability tests during hypoxic condition. Shots of Dennison in decompression chamber. This time he performs a series of mental ability tests, following decompression. Commentary by Beishon Dennison explains. Dennison discusses reasons for testing behaviour during state of hypoxia and the difficulties in modelling behaviour. He describes reasons for constructing models. C J Dickinson with the computer terminal on which he demonstrates his mathematical model of the human respiratory system. Dickinson explains how he came to build his computer model and what the model does: - it presents imaginary patients to which students, using a computer keyboard, can give various treatments. Shots of Dickinson operating the terminal to demonstrate his model. Behaviour of broncho-pneumonia patient when given 100% oxygen is simulated on the computer terminal. Eventual death results. Patient suffering from chronic periodic breathing is simulated. In this case the simulated treatment is a 3% CO2-Oxygen mixture. Breathing is seen to regularise on the terminal display screen. C J Dickinson discusses the extent to which complex physiological functions can be modelled with mathematical equations. D M Dennison explains the extent models are used at the Institute Aviation Medicine, Farnborough.
