Study Arms:
- Inhaled Treprostinil Placebo (Type: PLACEBO_COMPARATOR): A dose of placebo resembling inhaled treprostinil will be administered to all study participants in the placebo comparator arm prior to each of their Pulmonary Rehab sessions. A dose of inhaled albuterol will be administered prior to each inhaled agent. Vitals signs will be taken prior to administering the dose and no medication will be given if the systolic blood pressure in \< 85 mm Hg. Three puffs of inhaled trepostinil dose will be administered each time to all patients .
- Inhaled Treprostinil (Type: ACTIVE_COMPARATOR): A dose of inhaled treprostinil will be administered to all study participants prior to each of their Pulmonary Rehab sessions. A dose of inhaled albuterol will be administered prior to each inhaled agent. Vitals signs will be taken prior to administering the dose and no medication will be given if the systolic blood pressure in \< 85 mm Hg. Three puffs of inhaled treprostinil dose will be administered each time to all patients .

Based on this trial design, predict the completion outcome and termination type (if applicable).
