mPAP: mean pulmonary artery pressure; PVR: pulmonary vascular resistance; CI: cardiac index; SVR: systemic vascular resistance; PVR/SVR: ratio of PVR tp SVR; mSAP: mean systemic artery pressure; Pre: pre-inhalation value; Post: extreme value up to 60 min postinhalation (all extreme values are minimums except those marked with * which are maximum). Values are given as mean±sem for n=18 patients.
