ALL HANDS TO THE PUMPS SOCIETY When COVID-19 filled hospitals with patients with breathing difficulties, the UK’s engineering community rose to the challenge. In record time, engineers from disparate industries created production lines to make ventilators for intensive care units, redesigning equipment, negotiating unfamiliar certification processes, and building new supply chains almost overnight. Michael Kenward OBE discovered how engineering teams achieved this in weeks. running out of the respirators at the top of the country’s and ventilators that could VENTILATOR engineering companies and, provide oxygen to patients. CHALLENGE almost overnight, created the The NHS entered the On 16 March, the government consortium that came to be pandemic with 7,000 put out a call to UK industry to known as VentilatorChallengeUK ventilators.

Smiths racing industry also stepped standards. On 18 March, the Manufacturing Catapult with the Penlon ESO 2 ventilator. The consortium of more than 33 UK engineering and technology businesses from the aerospace, produced portable ventilators, in with McLaren, Williams and government asked industry to motorsport, automotive, and medical sectors produced more than 13,000 ventilators in 12 weeks in response to the COVID-19 pandemic, and received a President’s Special Award for Pandemic Service from the Royal Academy of Engineering © thisisjude.uk often used to move patients in other Formula 1 teams offering throw itself into the production ambulances, between wards the services of engineers who of what it called rapidly and in areas where connection suddenly saw their racing season manufactured ventilator systems to mains power is difficult. stranded in the pits.
