Modelling the lungs

Researchers at the universities of

and

are working on an EPSRC-funded project to create models of human lungs in order to optimise hospital ventilators.

Ventilators on an intensive care ward provide the oxygen that keeps patients alive when they are unable to breathe for themselves. However, the machines can leave patients with debilitating lung injuries and in some cases injuries are so serious the patient never recovers.

'The use of these ventilators - which mechanically inflate and deflate the lungs - can cause tearing. A patient could be left with lungs so badly scarred it could affect them for the rest of their life,' said Dr Jonathan Hardman, of Nottingham University’s Division of Anaesthesia and Intensive Care.

The £432,000 research project will enable Dr Hardman to work with control engineer Dr Declan Bates at Leicester University to produce computer models using data collected from patients on the Intensive Care Unit at Nottingham’s Queen’s Medical Centre.
