What percentage of patients with ARDS is considered highly fatal?

In acute respiratory distress syndrome (ARDS), a significant portion of patients exhibit high mortality rates, particularly in more severe cases. The percentage considered highly fatal is typically around 45-50%. This aligns with clinical studies indicating that as the severity of ARDS increases, so does the fatality rate due to complications such as multi-organ failure, secondary infections, and the underlying etiology of the lung injury itself.

The determination of mortality in ARDS can vary based on several factors, including the patient's age, comorbidities, the timing of diagnosis and intervention, and the presence of potential complications. Given these factors, understanding the high mortality rate of 45-50% can help emphasize the critical nature of early identification and management of ARDS in clinical practice.
