Supplemental Oxygen in Pulmonary Embolism (SO-PE)
Recruiting now · Early Phase 1
Conditions studied: Pulmonary Embolism, Venous Thromboembolism, Metabolomics, Oxygen Inhalation Therapy
In brief
A study of how supplemental oxygen helps patients with acute pulmonary embolism (PE). Hypothesis: Oxygen affects right ventricular dysfunction (RVD) in patients with acute pulmonary embolism (PE) primarily by relieving hypoxic pulmonary vasoconstriction and reducing pulmonary pressure (PA) pressure, and that this process is metabolically driven.
