What is the reported mortality rate of ARDS?

• A. 20%
• B. 30%
• C. 40%
• D. 50%

Answer: (C)

The reported mortality rate of acute respiratory distress syndrome (ARDS) is approximately 40%. This figure is derived from numerous studies and clinical data that analyze ARDS outcomes across various patient populations and settings. Mortality rates can be influenced by several factors, including the underlying cause of ARDS, the severity of the condition, and the presence of comorbidities.

In ARDS, the mortality rate can vary significantly based on how early it is diagnosed and managed, the effectiveness of supportive care, and advancements in treatment strategies such as the use of mechanical ventilation and adjunct therapies. While past data indicated mortality rates even higher than 40% in certain cohorts, advances in critical care have improved patient outcomes over the years.

Other options present lower or higher figures which may not accurately reflect the consensus in recent literature on ARDS mortality rates. Thus, the selection of 40% as the reported mortality rate aligns with current understandings in critical care and pulmonary medicine regarding ARDS.
