把氧释放(DO_2)和氧摄取率(O_2ER)的公式代入 Fick 等式,能得出表示组织氧合的一种新等式:VO_2=DO_2×O_2ER。如果同时检查所有相关的变量值,由 Fick 等式可得出一个可靠的组织氧合图象,这在临床实践中甚为重要。最近,一些临床家从控制呼吸机能不全和加强监护病人,而转向注意组织氧合作用的改变。原因是需 Substituting the formula for oxygen release (DO_2) and oxygen uptake rate (O_2ER) into the Fick equation yields a new equation for tissue oxygenation: VO_2 = DO_2 × O_2ER. If all the relevant variable values ​​are examined at the same time, a reliable tissue oxygenation image can be derived from the Fick equation, which is important in clinical practice. Recently, some clinicians have turned their attention to changes in tissue oxygenation, from controlling respiratory insufficiency and strengthening patient care. The reason is needed
