It might be helpful to read through the specs of what is being designed - it isn't simply connecting someone up to an air compressor... https://www.gov.uk/government/publications/coronavirus-covid-19-ventilator-supply-specification/rapidly-manufactured-ventilator-system-specification They are doing things properly, but with speed |

What you linked is exactly proof how all these "open crap respirators" and such are piece of crap, despite fact that many of those people have good intentions. You linked to professionally made specification by people that know what are they talking about. Read it carefully, and than go and, one by one, check all those "cowboy breathing devices" and tell us how many would have those specifications, parts and operating principle. Those that do comply with those specs are not "improvised devices", but real respirators, and than it can be argued if those can be used without formal approval process, and just after good functional test. Those that don't have all the functions listed there are simply not respirators, and are dangerous by design, because they cannot be used as respirators. |

What he linked to is what *we* are talking about, emergency build requirements for min spec COVID respirators thrown together in a hurry, exactly what Tesla is doing. |

And it still has to go through validation and approval... |

--- Quote ---Standards There are many standards that exist in this area. Below is a list of the most relevant ones. They are not formal regulatory requirements but many are harmonised against regulatory requirements. Consider them as helpful advisory standards for now. MHRA will lead an exercise to define which can be ‘safely’ relaxed for this emergency situation: BS EN 794-3:1998 +A2:2009: Particular requirements for emergency and transport ventilators ISO 10651-3:1997: Lung ventilators for medical use – emergency and transport BS ISO 80601-2-84:2018: Medical electrical equipment. Part 2 to 84. Particular requirements for basic safety and essential performance of emergency and transport ventilators – especially the parts on ‘patient gas pathway’ safety (very similar to IEC 60601) BS ISO 19223:2019: Lung ventilators and related equipment. Vocabulary and semantics --- End quote --- I think this is what I was referring to in the context of this discussion... |
