High Flow Oxygen and Low Dose Inhaled Nitric Oxide in a Case of Severe Pulmonary Hypertension and Obstructive Shock

      INTRODUCTION: Inhaled nitric oxide (iNO2) is an effective pulmonary vasodilator in treatment of pulmonary hypertension. Prior studies demonstrated a decrease in pulmonary arterial pressure and pulmonary vascular resistance and increase in cardiac output at a dosage between 20-80ppm. However, the effect of lower dosage in conjunction with high flow oxygen has not been well-studied.
