How to Calculate SpO2 to PaO2 (when no ABG available) When the PaO2is unknown because an ABG is not available, the SpO2measured by pulse oximetry can be used to approximate the PaO2,as shown in the Table below. *Note the SpO2/PaO2 conversion becomes unreliable when SpO2 is > 98%, but ...
Manual measurement: how to check your pulse rate For the manual measurement of the pulse rate, in addition to a hand as a “measuring instrument”, you need a display with a time recording possibility measuring in seconds. If you want to calculate the resting pulse rate, you should sit or...
We have seen how concentration and light path affect the absorbance of light. In addition to these, the pulse oximeter makes use of another important property to calculate oxygen saturation. That is, oxyhemoglobin and deoxyhemoglobin absorb light of different wavelengths in a specific way. Before w...
