BVM menu button
Insert the BVM cuvette into the BVM measuring head.
Calibration requirements:
– The BVM cuvette must be filled with a rinse solution.
– The temperature of the rinse solution exceeds 18 °C.
Cuvette calibration for increasing the measuring accuracy is performed
automatically. After successful calibration, the BVM symbol "Cuvette
calibrated" will be displayed.
Caution
If the measured RBV (relative blood volume), hemoglobin and
hematocrit values do not make sense for the patient, the measurement
results must be checked by means of an independent method before
deciding about further therapies.
When detecting blood inside the cuvette, the BVM automatically starts
the measurement and determines its reference of RBV = 100 %.
