Measure
IV Remodulin
The starting dose was 1 ng/kg/min (not to exceed to 2 ng/kg/min) and was titrated by up to 2 ng/kg/min every 2 hours, as tolerated and clinically indicated by the Investigator. Doses were titrated and maximized throughout the study until the desired clinical effect was observed or to each individual subject's maximally tolerated dose. There was no maximum dose. IV Remodulin: Treprostinil is a chemically stable tricyclic analogue of prostacyclin.
Placebo
The starting dose was 1 ng/kg/min (not to exceed to 2 ng/kg/min) and was titrated by up to 2 ng/kg/min every 2 hours, as tolerated and clinically indicated by the Investigator. Doses were titrated and maximized throughout the study until the desired clinical effect was observed or to each individual subject's maximally tolerated dose. There was no maximum dose.

OI is an assessment of how much oxygen from the lungs enters the blood when a subject inhales, calculated as: mean airway pressure (MAP) multiplied by fraction of inspired oxygen (FiO2) divided by partial pressure of oxygen in the arterial blood (PaO2), then multiplying by 100. An OI of 15 or less indicates mild hypoxia, 16 to 25 indicates moderate hypoxia, 26 to 40 indicates severe hypoxia, and more than 40 indicates very severe hypoxia.

PaO2/FiO2 ratio, also referred to as P/F Ratio, is a calculation used to assess the severity of hypoxemia, which is a condition characterized by low levels of oxygen in the blood. A low P/F ratio suggests that the patient's oxygen levels are compromised relative to the amount of oxygen being provided.

SpO2 is an assessment of how much oxygen is in the blood, measured by a pulse oximeter. Pre-ductal SpO2 is measured in the right hand or foot and is a reflection of the amount of oxygen flowing to the brain. Post-ductal SpO2 is measured in the left hand or foot, after the blood has mixed with less oxygenated blood from the rest of the body.

NT-proBNP is a hormone produced by the heart. Increased NT-proBNP concentration is associated with changes in right heart morphology and function. The main purpose of NT-proBNP testing is to see if the blood levels of this protein are within the expected range for a healthy individual.

IV Remodulin
n=20 participants at risk
The starting dose was 1 ng/kg/min (not to exceed to 2 ng/kg/min) and was titrated by up to 2 ng/kg/min every 2 hours, as tolerated and clinically indicated by the Investigator. Doses were titrated and maximized throughout the study until the desired clinical effect was observed or to each individual subject's maximally tolerated dose. There was no maximum dose. IV Remodulin: Treprostinil is a chemically stable tricyclic analogue of prostacyclin.
