Central venous and pulmonary artery occlusion pressures following air embolism in upright sheep.
A study on five upright (head above thorax) anaesthetised sheep demonstrated a statistically significant increase in central venous pressure and decrease in pulmonary artery occlusion pressure, following the injection of air 2 ml per kg into the pulmonary artery. In two out of the five sheep after air embolism, right-sided pressures equalled or exceeded those on the left, confirming their potential susceptibility to paradoxical air embolism.
