That's the CPAP that's a form of non-invasive ventilation. You can see why people outside the field are getting confused.Perhaps I am being picky - but hey, I am being picky -
the second photo is a CPAP device. It is not a ventilator.
Secondly - the Twitter feed says uses less oxygen than a ventilator.
Wrong - can't be. CPAP deliver 25 litres a minute in volume.
A ventilator usually scales upwards of 15 litres with capacity for more, but the purpose of the ventilator is not volume, but pressure to maintain expansion and nil collapse of the alveoli. This can sometimes be done with lower volumes. Also, the FiO2 delivered at the tissues doesn't need to be all oxygen as this leads to problems later on when trying to wean folk off.
