Ventilators aren’t a panacea for a pandemic like coronavirus

‘More ventilators!’ cried the journalists on Twitter. ‘Yes, more ventilators!’ replied the politicians. ‘Where are the ventilators?’ demanded the journalists, now screaming on television. ‘Yes, even more!’ replied the government, somewhat nonsensically. 

I am a critical care physician, specialising in the use of such machines. I’m flattered by all the attention our tools are receiving. But I fear the current clamour reminds me of nothing so much as the panic buyers of toilet-paper stampeding over each other in early March. When the history of the Covid-19 pandemic in the Western world is written, I do not believe ‘massive ramp-up of ventilator manufacturing,’ will be credited with our deliverance. Let me explain why.

Ventilators do not cure any disease. They can fill your lungs with air when you find yourself unable to do so yourself. They are associated with lung diseases in the public’s consciousness, but this is not in fact their most common or most appropriate application.
