The information we need is: 1. Percentage of patients who needed ventilation, got ventilation in good time, and recovered vs died. 2. Percentage of patients who needed ventilation, didn't get ventilation due to lack of resources, recovered vs died. Then we'll know how much ventilators are helping. I understand that prior to this pandemic, typical survival rates for patients who required invasive ventilation was in the region of 30%. 70% die even with ventilation. I've also heard that of Covid-19 patients that require ventilation, 80% die even with ventilation. So it has a slightly lower survival rate than other illnesses.
