Does anyone have any data on what percentage of acute respiratory presentations require ventilators? What about the average length of ventilator use?
About 7.3% of patients require ICU care. Among the patients who require ICU care, 56% require mechanical ventilation. This constitutes 4.1% of total covid-19 patients admitted to the hospital. Article Clinical course and outcomes of critically ill patients with...
Thank you for taking the time to respond. I looked at the Wuhan data (Yang et al) and have chosen to use 71.1% as the proportion of critically unwell respiratory patients requiring ventilators (i.e. 37 patients out of their 52 patient cohort) for my simulation.
Our local practice has been to discharge home suspected or confirmed CoVID-19 patients if they do not require oxygenation nor ventilation, and rely on their goodwill to self-isolate. I suspect our local data will have a rate of ventilatory requirement much higher than 4.1%.
According to the Wei-jie Guan et al. 6.1% of patients with COVID-19 required mechanical ventilation (including invasive 2.3%)

I note that the Victorian Government's mathematical modelling has chosen to use these figures:
Percentage of cases requiring hospitalization: 6%
Percentage of admissions requiring ICU: 30%
Percentage of ICU admissions requiring ventilation: 70%
Mean ICU stay: 10 days
