The survival rate of those infected with Covid 19 who are put on a ventilator is not easy to calculate. There are numerous factors that can affect the outcome, such as age and underlying medical conditions; however, studies have shown that for all patients, the mortality rate for those admitted to the ICU who require mechanical ventilation ranges from 41% to 75%.
In addition, research from the University of Washington found that patients hospitalized in critical care units due to COVID-19 and requiring mechanical ventilation had a mortality rate of 54%. In comparison, serious cases involving seasonal flu typically have an ICU admission mortality rate lower than 5%, highlighting how severe and life-threatening this virus is.
Furthermore, different countries may also show disparities in survival rates due to varying healthcare infrastructure or access resources. For instance, one study assessed outcomes among 108 critically ill patients with Covid-19 admitted between 1st January 2020–31st April 2020 across 55 hospitals in China. They found that out of these 108 critically ill adults (age > 15 years) requiring intensive care unit (ICU) support at least two weeks after hospital admission were placed on ventilators; only 34% survived until discharge from hospital.
Overall it is important to note there are limitations when looking at these figures as the data does not always account for other factors such as pre-existing health conditions or age which would further impact overall prognosis. However despite this information helps us understand overall trends regarding long term prospects and demonstrates why it is so essential we keep our distance during this pandemic in order to prevent further spread and severity of infection.
