Hi Geoff, I accept your points, but I don't think manufacturers will be able to fill the gap in such a short space of time. I have discussed the need for approx 8000 additional ventilators over the coming peak of covid-19. Every little helps.

Breas UK is ramping up ventilator production as the UK government calls on engineering firms to help.

Other suggestions of companies with medical equipment skills have included Meditec England

Be Proactive and reactive.
