F1 team helps build new UK breathing aid for Covid-19 patients | World news


A breathing aid that can help keep Covid-19 patients out of intensive care has been developed by mechanical engineers, medics and the Mercedes Formula One team.

The device, known as continuous positive airway pressure (CPAP), has been used extensively in hospitals in Italy and China to help coronavirus patients. It bridges the gap between an oxygen mask and the need for full ventilation, which requires sedation and an invasive procedure.

Symptoms are defined by the NHS as either:

  • a high temperature – you feel hot to touch on your chest or back
  • a new continuous cough – this means you’ve started coughing repeatedly

NHS advice is that anyone with symptoms should stay at home for at least 7 days.

If you live with other people, they should stay at home for at least 14 days, to avoid spreading the infection outside the home.

After 14 days, anyone you live with who does not have symptoms can return to their normal routine. But, if anyone in your home gets symptoms, they should stay at home for 7 days from the day their symptoms start. Even if it means they’re at home for longer than 14 days.

If you live with someone who is 70 or over, has a long-term condition, is pregnant or has a weakened immune system, try to find somewhere else for them to stay for 14 days.

If you have to stay at home together, try to keep away from each other as much as possible.

After 7 days, if you no longer have a high temperature you can return to your normal routine.

If you still have a high temperature, stay at home until your temperature returns to normal.

If you still have a cough after 7 days, but your temperature is normal, you do not need to continue staying at home. A cough can last for several weeks after the infection has gone.

Staying at home means you should:

  • not go to work, school or public areas
  • not use public transport or taxis
  • not have visitors, such as friends and family, in your home
  • not go out to buy food or collect medicine – order them by phone or online, or ask someone else to drop them off at your home

You can use your garden, if you have one. You can also leave the house to exercise – but stay at least 2 metres away from other people.

If you have symptoms of coronavirus, use the NHS 111 coronavirus service to find out what to do.

A team from University College London (UCL) and University College London Hospital (UCLH) have worked with Mercedes Formula One to adapt and improve existing CPAP in a process known as reverse engineering.

UCL said the device had now been recommended for use by the Medicines and Healthcare products Regulatory Agency (MHRA), which approves medical devices in the UK.

Developed in less than 100 hours from initial meeting to production of the first CPAP, 100 devices are now being delivered to UCLH for clinical trials, with the potential for a rapid rollout to hospitals nationwide.

Reports from Italy suggest about half of patients given CPAP have avoided the need for invasive mechanical ventilation.

The UCLH critical care consultant Prof Mervyn Singer said: “These devices will help to save lives by ensuring that ventilators, a limited resource, are used only for the most severely ill.

“While they will be tested at UCLH first, we hope they will make a real difference to hospitals across the UK by reducing demand on intensive care staff and beds, as well as helping patients recover without the need for more invasive ventilation.”

Prof David Lomas, the vice-provost for health at UCL, said: “This breakthrough has the potential to save many lives and allow our frontline NHS staff to keep patients off ventilators.

“It is, quite simply, a wonderful achievement to have gone from first meeting to regulator approval in just 10 days. It shows what can be done when universities, industry and hospitals join forces for the national good.”

CPAP machines are routinely used by the NHS to support patients in hospital or at home with breathing difficulties, but are said to be in short supply.

They work by pushing a mix of oxygen and air into the mouth and nose at a continuous rate, helping to increase the amount of oxygen entering the lungs.

Prof Rebecca Shipley, the director of the UCL Institute of Healthcare Engineering, said: “It’s been a privilege to work closely with our clinical colleagues and with doctors leading the Covid-19 response in China and Italy.

“This close contact has helped us to define the need, and respond with technology that we hope will support the NHS in the weeks and months to come.”

Prof Tim Baker, from UCL’s department of mechanical engineering, said: “Given the urgent need, we are thankful that we were able to reduce a process that could take years down to a matter of days.

“From being given the brief, we worked all hours of the day, disassembling and analysing an off-patent device.

“Using computer simulations, we improved the device further to create a state-of-the-art version suited to mass…
