Both PEEP and lipid infusions (LI) may alter pulmonary hemodynamics. The simultaneous effect of LI and PEEP were therefore investigated. Five adult anesthetized G\u00f6ttinger mini\u2010pigs were infused with a 20% LI at a high rate of 0.4 g\/kg\/hr for 30 min, followed by PEEP of 8 cm H<jats:sub>2<\/jats:sub>O for 15 min. Catheters were inserted into the upper vena cava, the pulmonary artery, the right and left atrium, and the aorta, and pressures recorded continuously. Ventilation volume, respiratory fractional gas concentrations of O<jats:sub>2<\/jats:sub> and CO<jats:sub>2<\/jats:sub> (mass snectrometer). and blood gases were measured. The following parameters were calculated : total peripheral resistance, pulmonary arteriolar resistance, right\u2010to\u2010left shunt (Q<jats:sub>s<\/jats:sub>\/Q<jats:sub>T<\/jats:sub>) dead space ventilation (VD\/ V<jats:sub>T<\/jats:sub>) and effective compliance.<\/jats:p><jats:p>Total peripheral resistance remained unchanged. Pulmonary arteriolar resistance increased significantly during PEEP, PEEP + LI, but not during LI alone. Q<jats:sub>S<\/jats:sub>\/Q<jats:sub>T<\/jats:sub> increased significantly during LI and returned to normal when PEEP was applied. V<jats:sub>D<\/jats:sub>\/V<jats:sub>T<\/jats:sub> and effective compliance did not change during LI. The increased right to left shunt, caused by LI, is reduced by means of PEEP, while the pulmonary arteriolar resistance increased with PEEP and
