Selection Of The Appopriate Pressure - MIETHKE M.blue plus Instruments Instrucciones De Manejo

GB | INSTRUCTIONS FOR USE
To determine the pressure level the
M.blue Check-mate is placed centrally
on M.blue. The M.blue Check-mate auto-
matically aligns itself over the valve.
The pressure stage can be read off
from the catheter in the proximal (lead-
ing to valve) direction. If the pressure
level is supposed to be adjusted, the
M.blue Check-mate is placed centrally
on M.blue. When doing so, the required
pressure stage must point towards the
proximal catheter (leading to valve). If
the M.blue Check-mate is now pressed
lightly onto the valve, the rotor brake in
M.blue is released and the pressure level
is set. When adjusting, please ensure
that the opening pressure is changed by
a maximum of 16 cmH 2 O per adjust-
ment process otherwise errors can result
(see Chapter "3. Adjustment process").

blue, pressure levels 0 to 40 cmH 2 O
CAUTION
Because of the magnets inside
the M.blue plus
M.blue plus Instruments may not
be used in the vicinity of active
implants such as heart pace-
makers. Furthermore, there is
risk of damage to MRI instru-
ments in their vicinity. Therefore,
usage of M.blue plus Instruments
is forbidden in such locations!

It is absolutely essential to use only the
M.blue plus Instruments to determine,
adjust and monitor the opening pressure
of the gravitational unit in M.blue. The
opening pressure of the differential pres-
sure unit in proGAV 2.0 can be deter-
mined, adjusted and monitored with the
described M.blue plus Instruments as
well as with the proGAV 2.0 Tools.

SELECTION OF THE APPOPRIATE
PRESSURE
Horizontal position
In the lying position, the gravitational
unit has no influence on the valve open-
ing pressure. In this position, the valve
opening pressure is thus determined
exclusively by the differential pressure
unit.
By default, a differential pressure unit
with an opening pressure of 5 cmH 2 O is
recommended.
Vertical position
The opening pressure for the vertical
Instruments,
body position is calculated from the sum
of the opening pressure in the differential
pressure unit and the gravitational unit
for both M.blue as well as proGAV 2.0.
Patient height, activity level and poten-
tially increased abdominal pressure
(obesity) should be taken into account
in selecting the opening pressure for
the gravitational unit (see pressure level
recommendations at https://www.mi-
ethke.com/en/products/downloads/).
