Acute Respiratory Distress Syndrome Definition, Causes, and Pathophysiology

Area of Science:

• Pulmonology
• Critical Care Medicine

Background:

• Acute respiratory distress syndrome (ARDS), first described in 1967, presents a significant healthcare challenge due to high mortality rates.
• Despite diverse causes, ARDS involves a distinct pattern of lung injury, characterized by severe hypoxemia and non-cardiogenic pulmonary edema.
• Extensive research and clinical trials have been conducted, yet ARDS remains a critical concern in patient care.

Purpose of the Study:

• To provide a comprehensive overview of acute respiratory distress syndrome.
• To review the clinical manifestations, diagnostic definitions, and various etiologies of ARDS.
• To offer a concise summary of the underlying pathophysiology of this complex respiratory failure.

Main Methods:

• Literature review of studies and clinical trials on acute respiratory distress syndrome.
• Synthesis of information regarding clinical presentation, definitions, and causes.
• Overview of the pathophysiology based on existing research.

Main Results:

• ARDS is a rapidly progressing respiratory failure with recognizable lung injury patterns.
• Key characteristics include severe hypoxemia and non-cardiogenic pulmonary edema.
• The syndrome arises from heterogeneous etiologies.

Conclusions:

• Acute respiratory distress syndrome remains a significant clinical and research challenge.
• Understanding its diverse causes, clinical features, and pathophysiology is crucial for management.
• Further research is needed to mitigate the high mortality associated with ARDS.
