Operation
Integrated Infant Scale
Integrated Infant Scale*
The weighing scale is located directly underneath the bed.
During the weighing process, the entire bed and all objects on it
are weighed. By lifting the patient, all other weights are deducted,
so that the baby's weight can be precisely determined.
The accuracy of the weight measurement is not limited by the
objects placed on the bed. These additional objects only reduce
the maximum displayable value of the scale by their combined
weight. In the event of patients needing circuits and lines, e.g.
ventilation circuits, the influence of these hoses on the measured
weight, as with other types of scales, cannot be fully eliminated.
In order to avoid fluctuating weighing results, the hoses should
be removed from the ventilation circuit support arm, if installed,
before weighing. Then, after placing the patient on the bed, the
hoses should also be laid on the bed in as strainfree and
horizontal a position as possible. Like items of clothing, if parts of
the hose lines are weighed with the patient, they can lead to a
slight increase in measured weight. Since these deviations are
systematic, they do not affect trend observations.
Weight measurements will only be completely accurate where
taring has been used. Without taring the level of accuracy will
be reduced. Changes made between measurements, such as,
changing in the tilt of the device or adding or removing objects
from the bed, may result in inaccurate results.
For weight measurements without using tare, particular atten-
tion must also be paid to ensuring vibration free conditions.
Pressing buttons on the control unit too forcibly may lead to
vibration that may reduce the accuracy of the weight measure-
ment. It is suggested that weighing should only be conducted
when the trolley castors on Caleo are locked. This helps to
cushion vibrations and increases the accuracy of weight
measurements.
Before weighing, check that the bed is fully pushed in and is in
the horizontal position.
The spirit levels show whether the bed is positioned horizontally.
