ENGLISH ABSTRACT: A significant decrease in lung volume is reported to occur in the dependent lung during OLA in the LDP. This decrease in lung volume can result in an acute increase in opposition to RV ejection. The potential problem is that the right ventricle is a thin walled structure that can generate considerably less work than the thicker walled LV. It possesses little reserve to deal with an acute rise in afterload as may occur during acute lung injury or after lung resection. Therefore, this increase in afterload during OLA may potentially impair RV-PA coupling. Albeit this potential problem exists, the changes in RV afterload and how the right ventricle performs during OLA have not been well studied. Arterial hypoxemia, due mainly to venous blood being shunted via the non-ventilated lung, may present a clinical problem during one lung ventilation. AFRIKAANSE OPSOMMING: ’n Betekenisvolle afname in volume van die onderlong vind in die laterale decubitus posisie tydens eenlongnarkose plaas. Hierdie afname in longvolume mag egter ’n akute verhoging in regter ventrikulêre nalading tot stand bring. Die probleem is egter dat die regter ventrikel ’n dunwandige struktuur is wat potensieel baie minder werk as die dikwandige linker ventrikel kan genereer. Die regter ventrikel het min reserwe om ’n akute verhoging in nalading te weerstaan soos wat gebeur met akute longbesering of na longreseksie. Dus die verhoging in nalading wat gepaard gaan met eenlongnarkose mag die koppeling tussen die regter ventrikel en die pulmonale arterie belemmer. Alhoewel hierdie potensiële probleem bestaan, is die verandering albei in regter ventrikulêre nalading en hoe die regter ventrikel funksioneer tydens eenlongnarkose nog nie goed bestudeer nie.
