Evolution of ARDS Definition
The definition of ARDS has evolved to incorporate changes in clinical practice, such as the use of high-flow nasal oxygen and ultrasound. Patients can now fulfill ARDS criteria with infiltrates diagnosed by ultrasound or hypoxia measured by saturations, even with high-flow nasal oxygen. The incorporation of the Gaglia modification allows patients on ward oxygen to be classified under ARDS, facilitating wider inclusion in clinical trials.
Management Challenges and Precision Medicine Approach
Management of ARDS remains limited, with emphasis on supportive care and adherence to guidelines. The shift towards a precision medicine approach aims to identify specific phenotypes within ARDS, like hyperinflatory and hypoinflatory types. This approach seeks to understand the distinct biological processes underlying each phenotype to target treatments more effectively and improve outcomes.
Long-term Impact and Future Considerations
Long-term outcomes of ARDS highlight significant morbidity extending beyond one to two years, including cognitive and psychiatric impacts, as well as societal challenges. The emphasis on proper ventilation in the ICU translating into lower mortality risk at two years underscores the importance of early interventions. Efforts to evolve towards more comprehensive multi-dimensional outcome assessments are crucial for designing effective clinical trials.
