Abstract

In the interval between the sampling of blood and analysis of the blood gas composition, the partial pressure of oxygen falls. The rate of fall depends on the temperature, initial level of partial pressure of oxygen in arterial blood, white cell and platelet count. Pseudohypoxaemia secondary to leukaemia and thrombocytosis can be recognized if the arterial blood sample is kept in ice until analysis can be carried out.

摘要

在血液采样与血气成分分析的间隔期间，氧分压会下降。下降速率取决于温度、动脉血中氧分压的初始水平、白细胞和血小板计数。如果将动脉血样本置于冰中直至能够进行分析，就可以识别出继发于白血病和血小板增多症的假性低氧血症。
