Recruiting NA High Altitude Pulmonary Hypertension

New treatment option for High Altitude Pulmonary Hypertension

Official title Inhaled Nitric Oxide for High Amplitude Pulmonary Edema (HAPE)

ClinicalTrials.gov ID: NCT06852924

What this study is testing

What it's testing
High Altitude Pulmonary Edema (HAPE) is a critical, non-cardiogenic pulmonary edema that manifests in high-altitude conditions, marked by the rapid onset of symptoms such as dyspnea, cough, frothy sputum, and cyanosis. It represents a significant cause of mortality among high-altitude illnesses due to its swift progression and elevated fatality rates if not addressed promptly.
