Abstract
A case is presented to illustrate the need for technical care when han dling blood gas samples. The physics of solubility are used to show ho w samples changed their oxygen tension (pO(2)) during handling while i nvestigating a clinical case to show the effect of hyperlipidemia on b lood gases. It appeared that inadvertent access to air allowed atmosph eric oxygen to equilibrate with the sample. The physical laws predicti ng the effect of partial pressure and temperature on gas solubility in a liquid are illustrated by the pO(2) levels measured in this case. E ffects due to hyperlipidemia were not observed. The calculations are d escribed in detail. Brief suggestions for sample handling to avoid mis leading results from such cases are discussed.
