Primary Outcome Measures:

To assess the safety of Tyvaso ® as assessed by changes or stability of acute oxygenation (pulse oximetry) and spirometry (FEV1). [ Time Frame: This is a 4 week trial ]
A 4-Week, Open Label Study Testing the Safety of Inhaled Treprostinil (Tyvaso®) in the Treatment of Pulmonary Hypertension (PH) Associated with Chronic Obstructive Lung Disease (COPD) (PH-COPD)

Secondary Outcome Measures:

New York Heart Association (NYHA) functional class [ Time Frame: Change in New York Heart Association (NYHA) functional class assessed at baseline and at week 4. ]
A change in functional class is assessed as improvement or deterioration in the patient's functional status
Six minute walk distance [ Time Frame: Change from baseline in 6 minute walk distance at 4 weeks ]
A change in how far the subject can walk in 6 minutes will be measured at baseline and compared to how far the subject can walk in 6 minutes at week 4.
Clinical Worsening [ Time Frame: From the time of randomization to until the subject discontinues from study for any cause, assessed up to 4 weeks ]
Clinical worsening is described as Death, hospitalization (all cause)and COPD exacerbations (worsening of respiratory symptoms which require treatment with oral corticosteroids, antibiotics or both).
Peripheral Blood Mononuclear Cells (PBMC) phagocytic index (PI) and PBMC gene expression [ Time Frame: Change from baseline in PBMC PI and PBMC gene expression at 4 weeks ]
The phagocytic index is the average number of bacteria ingested per phagocyte in an incubated mixture of bacteria, phagocytes, and blood serum. We will also be looking a a change in gene expression of these (PBMC) cells.
St. George's Chronic Obstructive Pulmonary Disease (COPD) questionnaire [ Time Frame: change from baseline in the St. George's respiratory questionnaire at 4 weeks ]
The St. George's questionnaire is a quality of life questionnaire completed by the subject at baseline and at week 4.

Arms	Assigned Interventions
Experimental: Treprostinil Inhaled prostanoid therapy with Treprostinil	Drug: Inhaled Treprostinil Therapy Treprostinil: Inhaled prostanoid therapy Other Name: Tyvaso ®

Detailed Description:

This is a pilot study of 10 patients that have COPD-PH. Primary outcome measure is to see if this drug is safe for this patient population and the secondary measure is to see if the drug improves patient functional capacity.
