4 Clinical Trials for Various Conditions
The purpose of this study is to determine if the events leading to smoking-associated centrilobular and paraseptal emphysema are caused by a failure of the lungs' inherent mechanisms to block hypoxic pulmonary vasoconstriction (HPV) in areas of smoking-induced inflammation.
The purpose of this study is to evaluate the effects of Dexmedetomidine when used during thoracic surgery. The primary outcome will be changes in oxygenation as measured the PaO2 during one lung ventilation.
The objective of this study is to determine if single dose administration of inhaled iloprost will reduce pulmonary artery pressure, reduce hypoxic pulmonary vasoconstriction and improve arterial oxygenation at rest and during exercise at high altitude.
