What is the approximate mortality range for ARDS?

• A. 10-20%
• B. 40-60%
• C. 70-80%
• D. 25-35%

Answer: (B)

The key idea is that ARDS carries a substantial risk of death, especially as the illness is more severe and patients have other illnesses or organ failure. Mortality isn’t a single number for all cases; it’s higher in more severe ARDS and in older or sicker patients, even with current best practices like lung-protective ventilation and careful management. Among the options, 40-60% best captures the typical range seen in many ARDS cohorts, particularly when considering the more severe end of the spectrum. Lower ranges such as 10-20% or 25-35% tend to underestimate the risk for most ARDS patients, while a very high range like 70-80% is not representative of the majority of cases under modern ICU care (though mortality can be higher in particularly ill subgroups). So, the 40-60% range is the most appropriate approximate estimate.
