difference
C(a-v)O2=CaO2×CvO2
O2ER %
oxygen extraction
ratio
O2ER=（CaO2－CvO2）/ CaO2
DO2 mL/min oxygen transport DO2=C.O.×CaO2

19.6. Ventilation Calculations
The monitor provides the ventilation calculation function. The monitor can save the
results of up to 20 calculations, which are displayed in groups.
19.6.1. Calculation Step
The ventilation calculation steps are as follows:
1. Access ventilation calculation page by either of the following ways:
 Select【Calculations】quick key【Ventilation】submenu .
 Select【Main Menu】quick keyfrom 【Calculations】 column to
