What this trial studies

This study investigates the hemodynamic effects of nasal high-flow therapy in patients suspected of having precapillary pulmonary hypertension. It aims to measure changes in cardiac output during right heart catheterization and echocardiography, hypothesizing that nasal high-flow will enhance cardiac output. The study will utilize echocardiography to assess the sensitivity of detecting cardiovascular changes resulting from this therapy.

Who should consider this trial

Good fit: Ideal candidates are patients undergoing right heart catheterization for suspected or monitored precapillary pulmonary hypertension.

Not a fit: Patients requiring more than 21% oxygen during the procedure or those with severe cardiac conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve the management of pulmonary hypertension by enhancing cardiac function.

How similar studies have performed: While similar studies have explored high-flow therapies, this specific approach in the context of pulmonary hypertension is relatively novel.
