CPAP machines are less invasive than a fan

for breathing assistance, which can help keep coronavirus in patients from the intensive care unit in under a week.

University College London engineers worked with doctors at UCLH and Mercedes Formula One to build The Device supplies oxygen to the Lungs , without The Need for a fan.

Continuous Positive Airway Pressure (CPAP) devices are already being used in hospitals, but are In Short supply.

China and Italy used to help you, Covid-19 patients.

Forty new devices ULCH and three other London hospitals have been delivered. If studies go well, up to 1,000 of the CPAP machines made per day by Mercedes-AMG HPP, the beginning can be in a week.

The medicines and Healthcare products Regulatory Agency (MHRA) has already given his consent for their use.

Meanwhile, a consortium of British industry -, technology-and engineering businesses in the UK have come together to produce the respirators for the NHS.

"VentilatorChallengeUK" consortium includes Airbus, Bae Systems , Ford, Rolls-Royce and Siemens.

companies in the consortium received orders for More Than 10,000 fans of the government, although the health authority (MHRA) approval is still pending.

the production is due to start next week.

Dick Elsy, chief executive, High value manufacturing, said: "This consortium brings together some of The Most innovative companies in The World .

"are you together with an incredible determination and energy in order to scale-up the production of much-needed fans, and fighting a virus, the people in many countries. "

What I need to know about the coronavirus? Quick response

Prof Rebecca Shipley, Director of the UCL Institute of Healthcare Engineering, told The Bbc : "in General, medical device development would take years, but we have done that in the days since we went Back To produce a simple existing device and "reverse-engineered", in order to be able, and to scale quickly. "

Reverse-engineering means that you took next to an existing off-patent-CPAP-device copies and improves the design and adapted for Mass Production .

Prof Shipley, and Prof Baker helped in the development of The Device

Early reports from the Lombardy region in Italy suggest that More Than 50% of the patients, the avoided CPAP, The Need for invasive ventilation.

UCLH Critical Care consultant Prof Mervyn Singer said: "These devices are an in-between thing between a simple oxygen mask and invasive ventilation the patient requires to be sedated.

"you will help to save lives, by ensuring that the fans, is a limited resource, available only to The Most seriously ill. "

How does the CPAP work?

It pushes a steady flow of air-oxygen mixture in The Mouth and nose of the patient.

This is done to pressure, which means that the Lungs remain open, and so it increases the amount of oxygen input.

This reduces the effort required to breathe, especially when the alveolar vesicles of the lung in the lung have collapsed as a result of the Covid-19.

in contrast to a simple face mask connected to an oxygen supply, CPAP delivers air and oxygen Under Pressure , so it must be a mask to create a tight seal on the patient's face, over her mouth and nose, or a transparent hood over your head.

This is less of a device invasive than a ventilator, to patients heavily sedated and a tube inserted in your airway.

But a note of caution was sounded by Duncan Young , Prof of Intensive Care Medicine, University of Oxford, said: "The use of CPAP devices for patients with contagious respiratory infections is somewhat controversial, as are any small leaks round The Mask and spray droplets of secretions on could, to the participation of clinical staff. "

Prof Mervyn Singer said that when a seal is maintained on The Mask or, better yet, a helmet is worn, and the clinical staff have sufficient personal protective equipment (PPE), then would minimize the risk.

More Than 2,000 Covid-19 patients in the CPAP in General wards in Lombardy.

Andy Cowell , Managing Director of Mercedes AMG High Performance Powertrains, said: "The Formula One community has shown an impressive response to The Call for the support... we deliver proud of our resources in The Service of the UCL to the CPAP project to the highest standards and in the quickest possible time frame. "

As well as the Mercedes F1, The Collaboration also included the Oxford contain Optronix, a small company that has produced, oxygen monitors for the devices.
