UK scientists to produce high-performance ventilators at low cost

The High Energy Ventilator, which the HPLV prototype will be based on.

UK scientists have been awarded funding to develop a robust, low-cost ventilator to help patients in low and middle-income countries suffering from severe respiratory problems due to COVID-19.

Mechanical ventilation is a small but important part of the management of pandemic virus infections which affect the lungs, including:

  • SARS-CoV-1
  • SARS-CoV-2 (COVID-19)
  • influenza.

Ventilators are typically expensive to purchase and maintain, and need considerable training to use. Most also rely on the provision of high-flow oxygen and medically pure compressed air, which are not readily available in many countries around the world.

Affordable, reliable and easy to use

A team of scientists aims to produce and test plans for the creation of an affordable, reliable and easy-to-operate ventilator which does not rely so heavily on compressed gases and mains electricity supply.

The team is coordinated by the Science and Technology Facilities Council’s (STFC) Daresbury Laboratory.

It is anticipated that these plans will be used by a wide variety of manufacturing groups across the world, thereby reducing the need for expensive transportation and maintenance.

The Head of the Technology Department at STFC’s Daresbury Laboratory, Ian Lazarus, is the project lead. He said:

I am proud to be leading this team, in which we have brought together experts from medicine, science, engineering and knowledge transfer with a shared goal to make resilient high quality ventilators available in areas of the world which currently don’t have enough of them.

We look forward to redeploying skills that normally underpin science research into this different and very necessary field, working with medical experts in both UK and Brazil. Together we hope to make a positive impact in the current fight against COVID-19 and afterwards in the treatment of other respiratory conditions in countries where ventilators are not as readily available as they are here in the UK.

International expertise

As well as leadership from Daresbury Lab, teams across STFC will be working on this project, from:

  • Technology Department
  • Hartree Centre
  • ISIS Neutron and Muon Source
  • Business and Innovation Department (BID).

STFC will also be working with international partners from:

  • Federal University of Rio de Janeiro (Brazil)
  • CERN
  • University of Birmingham
  • University of Liverpool
  • Medical Devices Testing and Evaluation Centre (MDTEC).

The £760,000 funding for the prototypes has been awarded by UK Research and Innovation (UKRI) through the Global Challenges Research Fund (GCRF). GCRF looks to support scientists to develop solutions to mitigate the short and long-term social, economic and health impacts of the pandemic.

Real-world applications

This project, known as the High Performance Low Cost Ventilator (HPLV), builds on the original designs for the High Energy physics Ventilator (HEV).

The HEV was developed at CERN by a group of institutes from the LHCb collaboration, with guidance from:

  • local hospitals
  • an international team of medical experts
  • specialists such as the World Health Organisation.

Professor Themis Bowcock, of the University of Liverpool, instigated the train of events leading to HEV and HPLV. He is part of the LHCb experiment team at CERN and the original HEV team, as well as a member of the ‘CERN against COVID’ committee and the WHO Expert Respiratory Panel. Themis said:

It is of enormous importance to us that the technology and software techniques we developed for fundamental physics at the Large Hadron Collider will be used to support the international community in the COVID-19 era. This shows that expertise of researchers across the whole UKRI portfolio play a part in tackling urgent and acute challenges faced by humanity.

A common goal

The HEV prototype design, which was developed using research techniques routinely used at CERN, will now be re-engineered to make it ready for regulatory approval and for manufacture.

HEV team leader Paula Collins, part of the LHCb experiment at CERN and a CERN physicist, said:

HEV was born at CERN during the first lockdown thanks to a dedicated team of physicists and engineers who adapted their expertise to fight the pandemic.

We are grateful to our international team of medical advisers who helped us to orient the HEV design towards the needs of low and middle-income countries, and to build a ventilator focused on quality and patient comfort.

We warmly welcome the HPLV initiative, which will build upon the success of HEV and we look forward to working together with the outstanding HPLV team for our common humanitarian goal.

A team effort

During the HPLV project, partners based in Brazil will identify difficulties encountered when ventilating patients. That information will be passed to the design team, while regulatory experts in the UK will also provide valuable guidance on this re-engineering activity.

The STFC BID team will work closely with their counterparts in CERN’s Knowledge Transfer group to identify industrial partners who will manufacture and supply the HPLV ventilators.

The project will run for six months from October 2020 to April 2021. A small amount of funding in the following 12 months will support the transfer of the HPLV technology to industrial partners.
