[Acute respiratory distress syndrome]

Area of Science:

• Critical care medicine
• Pulmonology
• Pathophysiology

Context:

• Acute respiratory distress syndrome (ARDS) presents significant challenges in intensive care settings, characterized by high prevalence, mortality, and morbidity.
• Since its initial description in 1968, substantial research has advanced the understanding of ARDS pathophysiology, diagnostics, and prognosis.

Purpose:

• To summarize the current understanding and management strategies for Acute Respiratory Distress Syndrome (ARDS) based on the 2012 Berlin definition.
• To highlight key advancements in diagnostics, mechanical ventilation, and supportive care for ARDS patients.

Summary:

• The 2012 Berlin ARDS definition aids in bedside identification of patients.
• Key management principles include lung-protective ventilation with appropriate positive end-expiratory pressure (PEEP), fluid management, and patient positioning to minimize ventilator-induced lung injury (VILI).
• Despite improved understanding and supportive care, specific causal treatments for ARDS, beyond addressing underlying infections, are still lacking.

Impact:

• ARDS management has evolved, focusing on lung protection and supportive measures, leading to better patient outcomes.
• Survivors of ARDS frequently experience significant long-term sequelae, necessitating ongoing research into post-ARDS care and rehabilitation.
• Continued research is crucial for developing effective causal therapies and improving long-term recovery for ARDS patients.
