I have to say I'm a little bit surprised at what is still used as PPE in the health service , it seems we are still looking at it from a century ago , with paper masks ( which if we are honest are fairly useless as they will always draw air in from round the edges rather than filter through the paper ) and simple masks
I have a Tribord Easybreath full face snorkel mask , it is air and watertight , it offers good visibility and is comfortable to the point I've spent up to 40 minutes in the water without taking it off , surely something similar to it , combined with either a reusable or disposable filter could be designed that would provide much better protection
The question of sterilising could easily be solved by either steam ovens or UV light
Give as we have seen with the ventilators , a specification for a full face , fan air fed mask using rechargeable batteries to a Dyson or G Tech , and something could be produced at reasonable cost
It seems to me that we can spend trillions developing electric cars that will not save the planet no matter what anybody tells me , and similar developing wonderful health machinery , but something as simple as providing a safe environment for health staff is virtually the same as Ms Nightingale had ?
