[Acute respiratory distress syndrome]

Area of Science:

• Critical Care Medicine
• Pulmonology
• Emergency Medicine

Background:

• Acute respiratory distress syndrome (ARDS) is characterized by pulmonary edema resulting from diverse lung injuries.
• A revised ARDS definition in 2012 incorporated hypoxemia severity and positive end-expiratory pressure (PEEP) levels.
• Significant advancements in intensive care and organ failure support have contributed to improved patient outcomes.

Purpose of the Study:

• To review the current understanding and management strategies for Acute Respiratory Distress Syndrome (ARDS).
• To highlight the impact of protective mechanical ventilation on reducing ventilator-induced lung injury (VILI).
• To discuss established and emerging therapeutic interventions for ARDS.

Main Methods:

• Review of current literature and clinical guidelines for ARDS management.
• Analysis of treatment strategies including causative treatment, mechanical ventilation, PEEP titration, prone positioning, and inhaled nitric oxide.
• Evaluation of the evidence for adjunctive therapies such as extracorporeal membrane oxygenation (ECMO).

Main Results:

• Mortality rates in ARDS patients have decreased due to improved critical care and the adoption of protective ventilation strategies.
• Protective mechanical ventilation has been crucial in mitigating ventilator-induced lung injury (VILI).
• Established treatments involve addressing the underlying cause, implementing protective ventilation with PEEP (10-15 cm H2O), prone positioning, and inhaled nitric oxide for severe cases.

Conclusions:

• The prognosis for ARDS patients has significantly improved, largely attributed to protective mechanical ventilation and enhanced critical care.
• Current treatment protocols emphasize a multi-faceted approach including ventilation strategies and specific interventions based on severity.
• The role of extracorporeal membrane oxygenation as an adjunctive therapy for ARDS requires further investigation.
