Hemodynamic Effect of Nasal High-flow in Patients Suspected or Followed for a Precapillary Pulmonary Hypertension

Summary

In this study, the investigators aim to describe the hemodynamic consequences of nasal high-flow measured during right heart catheterization and echocardiography. The research hypothesis is that nasal high-flow would increase cardiac output in patients with pulmonary hypertension. The concomitant echocardiography will allow to describe its sensibility to detect cardiovascular consequences of nasal high-flow.

Eligibility

Inclusion Criteria:

\- patient addressed for right heart catheterization for pulmonary hypertension suspicion or follow-up.

Exclusion Criteria:

* necessity of FiO2 \>21% during right heart catheterization
* intracardiac shunt
* grade 4 tricuspid insufficiency
* complete arrhythmia due to atrial fibrillation
* Pregnant or breastfeeding women or women of childbearing age without an effective method of contraception
* protected adult patient (tutorship or curatorship)
* patient deprived of liberty by court or administrative decision
* refusal of patient participation or consent
* patient for whom the measurement of pulmonary arterial pressures during right heart catheterization is impossible
* patient for whom, during the etiological assessment of pulmonary hypertension, the diagnosis of precapillary pulmonary hypertension cannot be confirmed and classified in groups 1, 3 or 4.
