SaO2 can be measured either by ABG analysis or by pulse oximetry. SaO2 refers to the amount of oxygen bound to hemoglobin in arterial blood. SpO2 simply means that the SaO2 was measured using pulse oximetry.aO2 is an invasive measure of the % of Oxyhemoglobin (oxygen saturated hemoglobin) in the blood using lab tests on arterial blood. SpO2 noninvasive measure the % of saturated hemoglobin in the capillary bed and does not identify what is saturating the hemaglobin.
The INDIRECT() function lets you get the value in a cell by means of an indirect reference. Indirect reference means that you refer to the address of the cell rather than to the cell itself.Thus, INDIRECT(B2) does not return the value in cell B2, but rather the value in the cell whose address is in cell B2. So, if cell B2 contains the text H5, the above function will return the value in cell H5.he INDIRECT() function lets you get the value in a cell by means of an indirect reference. Indirect reference means that you refer to the address of the cell rather than to the cell itself.
