Klaus Vennick Marcussen

Klaus Vennick Marcussen is a Clinical Associate Professor in the Department of Clinical Medicine at the University of Copenhagen, specializing in Anaesthesiology. His research focuses on evidence-based interventions in critical care settings, with extensive contributions to COVID-19 therapeutic strategies and oxygenation management.

Research Focus:
Dr. Marcussen's work centers on optimizing critical care protocols through multinational clinical trials. His primary interests include:

• COVID-19 respiratory failure management
• Dexamethasone efficacy for severe hypoxemia
• Oxygenation target strategies in ICU
• Post-surgical pulmonary complications
• Septic shock pathophysiology

Publication Trends:
Recent works (2021-2025) demonstrate strong focus on pandemic response, with 75% of publications analyzing COVID-19 interventions. Key themes include randomized trials of dexamethasone dosing (COVID STEROID 2), oxygenation protocols (HOT-COVID), and mechanical ventilation strategies. Earlier research (2010) established foundations in septic shock management.
