Supplemental Oxygen in Pulmonary Embolism (SO-PE)
This study examines whether giving extra oxygen to patients with acute pulmonary embolism (a blood clot in the lungs) can help improve heart function. Researchers believe oxygen may reduce pressure in the lungs and help the right side of the heart work better during this serious condition.
Key Objective: The trial tests whether supplemental oxygen can reduce strain on the heart and lower lung pressure in patients with acute pulmonary embolism.
Who to Consider: Patients recently diagnosed with acute pulmonary embolism who are experiencing right ventricular dysfunction should consider enrolling.
Trial Parameters
Brief Summary
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.
