Nicely found Trevor!
Karl - didn't know you are involved with ventilator products.
I remember when I started in ICU we still used Birds Machines.
Oddly all this talk of intubation/ventilation where I am, the public believe (or should I say the media) it's available for "everyone". In my day the maximum number of tubed patients in ICU was five - for a population of around 60,000.
If another tubed patient needed to be admitted - there were 2 options. The intensivist looked long and hard at who was being ventilated and decide if withdrawing treatment on someone was possible (very rare, but it sometimes happened especially if the prognosis was poor) or transferring one of them to Sydney - which is usually what happened.
If lungs fail on mass as a result of COVID - we'll be in serious ventilation trouble.
I'm presently watching and reading the Ward and Burns series/book on the Vietnam War.
