London | researchers, physicians and engineers team Mercedes Formula 1 have developed in less than a week, respiratory support, to relieve the lungs of patients with the new coronavirus, avoiding to place them under respirators.
The principle of this device, known under the acronym CPAP (continuous positive airway pressure), has been widely used in hospitals in Italy and in China to help the sick of the Covid-19 with severe lung infections breathing when the oxygen masks are not sufficient, said in a press release from the University College London (UCL).
The engineers at UCL have worked tirelessly since the march 18, with doctors from the University College London Hospital (UCLH) and the team Mercedes to adapt and improve a CPAP, what they have achieved in less than a hundred hours of work.
Regulatory Agency of medicines and health products (MHRA), which approves medical devices in the Uk, has now given its green light to the use of this device, said UCL.
A hundred devices will be delivered to the UCLH for clinical trials prior to a rapid deployment in the hospitals of the country, which is expecting a wave of arrival of patients Covid-19.
Reports from Italy indicate that approximately half of the patients with a CPAP have avoided devices more invasive.
The CPAP consists in spreading a mixture of air and oxygen in the mouth and the nose at a continuous pace, keeping the airway open, and increasing the amount of oxygen entering the lungs.
Respirators invasive, them, require a strong sedation of the patient, as well as a connection to a tube placed in the trachea of the patient.
The devices which have just been developed “to help save lives by ensuring that respirators, of which the number is limited, to only be used for people who are more seriously ill,” said professor Mervyn Singer, a consultant in intensive care at UCLH, quoted in the press release.
In some european hospitals, in Italy or Belgium, such respiratory aids have been designed by adapting diving masks.
