Operation method: select a compensation type (GENERAL, O2, DES or ALL) as
described above, and then select to turn ON or OFF the water vapor compensation
(VA) and BTPS compensation.
„ WATERVAPOR Water vapor compensation
Options: ON and OFF.
Water vapor compensation is based on the feature that CO
2
absorbs infrared rays.
Normally, the patient’s exhalation contains some water vapor, which may adversely
affect the measurement result. Thus, the water vapor compensation should be turn
ON. When measuring dry gas, however, the water vapor compensation should be
turned OFF. For example, the water vapor compensation is not necessary when
measuring the CO
2
content inside an incubator.
