Work of breathing Work of breathing Work of breathing (WOB) is the energy expended to inhale and exhale a breathing gas. It is usually expressed as work per unit volume, for example, joules/litre, or as a work rate (power), such as joules/min or equivalent units, as it is not particularly useful without a reference to volume or time. It can be calculated in terms of the pulmonary pressure multiplied by the change in pulmonary volume, or in terms of the oxygen consumption attributable to breathing. In a normal resting state the work of breathing constitutes about 5% of the total body oxygen consumption.
CAP Scientific team, working with both surface and submarine fleets, and a Land Air Systems business also took research and development contracts and was prime contractor for the British Army's Brigade and Battlegroup Trainer (BBGT). The non-defence scientific sector was addressed by setting a Scientific Systems business with expertise in energy generation and conservation. In that year, CAP Scientific established the Centre for Operational Research and Defence Analysis (CORDA) as an independent unit to provide impartial assistance for investment appraisal. At that time military computer systems were purpose-built by major contractors, and CAP Scientific's strategy was to form joint ventures with companies
