Re: So, Musk bought a thousand ventilators
Erm... Elon is not the dickhead that is being portrayed. The NHS is now actively using CPAP machines with an added oxygen feed (either by using an inline "T" valve or using the masks that are already adapted for adding extra oxygen). Their purpose to provide added support before patients become too sick, to prevent them having to require sedation and ventilation in a full service ICU bed.
In other words it is successfully being used for new patients that present with breathing difficulties but can manage with extra oxygen and nursing. Another side benefit is that CPAP machines used in this way don't need 50L of oxygen a minute and this allows more patients to be hooked up the hospital oxygen system at a time.
Finally CPAP machines are available, they work, and are relatively cheap (£300/£500 a pop to the NHS). Cheaper still if Mercedes F1 get their way. They say they can produce 1000 units per week, starting next week.
