Lessons Learned in Mechanical Ventilation/Oxygen Support in Coronavirus Disease 2019

Area of Science:

• Critical care medicine
• Infectious diseases
• Pulmonology

Background:

• Coronavirus disease 2019 (COVID-19) presents a wide clinical spectrum, frequently leading to severe acute respiratory distress syndrome (ARDS) and multiorgan dysfunction.
• The management of COVID-19 ARDS has evolved significantly throughout the pandemic in response to emerging clinical evidence.
• Mechanical ventilation is a cornerstone of supportive care for severe COVID-19 ARDS.

Purpose of the Study:

• To review the historical evolution of ventilatory management strategies for COVID-19 ARDS.
• To synthesize current evidence-based recommendations for mechanical ventilation in COVID-19 ARDS.
• To provide a comprehensive overview of treatment adjustments based on pandemic-driven research.

Main Methods:

• Literature review of clinical studies and guidelines on COVID-19 ARDS management.
• Analysis of changes in ventilatory strategies over time.
• Synthesis of current best practices for mechanical ventilation.

Main Results:

• Initial management often involved lung-protective ventilation, with subsequent adaptations based on evolving understanding of COVID-19 pathophysiology.
• Strategies such as prone positioning, high PEEP, and neuromuscular blockade have been refined.
• The evidence base for specific ventilator settings and adjuncts has grown considerably.

Conclusions:

• Ventilatory management for COVID-19 ARDS has shifted towards more tailored and evidence-based approaches.
• Continuous re-evaluation of treatment protocols is crucial for optimizing patient outcomes in ARDS.
• Current recommendations emphasize lung-protective ventilation, prone positioning, and individualized PEEP titration.
