15 Michigan sites being considered for field hospitals during coronavirus crisis

  15 Michigan sites being considered for field hospitals during coronavirus crisis Among the proposed locations are the 725,000 sq. ft. TCF Center, the Detroit Pistons Performance Center and two dormitories at Wayne State University. Those proposed locations are all in Detroit. After selecting and securing the property to be used as field hospitals, the U.S. Army Corps of Engineers converts and equips the facility for health care use and maintains operations before restoring the site to its original condition when its services are no longer needed.

Mercedes Formula One engineers and researchers at University College London have together created a coronavirus breathing aid in less than 100 hours that has been approved for use within the UK's National Health Service.

Since March 18, the researchers and engineers have been working to develop the breathing devices together with clinicians at UCL Hospital, where they will now undergo clinical trials. The aids have already been cleared for use by the UK's regulator, the Medicines and Healthcare products Regulatory Agency (MHRA), and Mercedes can begin producing 1,000 machines per day in a week's time for immediate delivery to hospitals.

How Tesla Engineers Are Using Model 3 Parts to Build Ventilators

  How Tesla Engineers Are Using Model 3 Parts to Build Ventilators The new process follows a previous Elon Musk snafu.Now, Tesla is giving us a glimpse into its process. In a new video (seen above), company engineers break down how they're repurposing Tesla parts to build ventilators for COVID-19 (coronavirus) patients—something that Ford and General Motors have also been doing, thanks to the stockpiles of parts that auto manufacturers keep on hand to maintain a buzzing assembly line.

"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," said UCL Mechanical Engineering Professor Tim Baker in a statement. "From being given the brief, we worked all hours of the day, disassembling and analysing an off-patent device."

The aid is known as a Continuous Positive Airway Pressure (CPAP) machine, and it fits over a patient's mouth to help them breathe by pushing an air-oxygen mix into the mouth and nose at a continuous rate. It's a less invasive alternative to the ventilators that require patients to be sedated and intubated -- an intervention necessary to treat the most serious cases.

Helmut Marko: Austrian GP in Spielberg "has to go out"

 Helmut Marko: Austrian GP in Spielberg © Motorsport Images Formula 1 in Spielberg: The race is (still) in the 2020 calendar As of now, the Austrian Grand Prix in Spielberg would be the third race of the formula -1 season 2020. However, given the ongoing coronavirus situation, it is uncertain whether the event can really be held. Red Bull sports director Helmut Marko is still confident. In an interview with 'Austria', which was held before Baku's latest Formula 1 event was canceled, Marko said: "[The race] has to run out.

With ventilators in short supply in the UK, as they are in many places across the world, the hope is that the CPAP devices will reduce the number of people who need to be admitted to intensive care and put on a ventilator after being hospitalized with COVID-19. According to UCL's press release, reports from Italy indicate that approximately 50% of patients given CPAP have avoided the need for mechanical ventilation.

"These devices will help to save lives by ensuring that ventilators, a limited resource, are used only for the most severely ill," said UCLH Critical Care Consultant Mervyn Singer in a statement.

The production of CPAP machines complements wider efforts by the UK manufacturing industry to produce more ventilators. These include a project by Dyson, which has developed its own ventilator (although it still needs approval from the MHRA), and an effort by a consortium of auto makers and other engineering companies to manufacture ventilators based on an existing design.
