This is a non-binding recommendation for
the treating physician. The physician decides
on each case independently, individually and
autonomously in accordance with his/her diag-
nosis.
The adjustable differential pressure unit of the
proGAV 2.0 XABO is set to an opening pres-
sure of 5 cmH O upon delivery.
This pre-set opening pressure can be changed
to a different pressure prior to implantation.
The opening pressure in the horizontal body
position is determined by the differential pres-
sure unit.
Depending on the patient's clinical picture, indi-
cation and age, the opening pressure for this
position can be selected between pressure lev-
els from 0 to 20 cmH O.
The opening pressure of the proGAV 2.0 XABO
for the vertical body position is calculated from
the sum of the opening pressure of the differ-
ential pressure unit and the gravitational unit.
Patient height, activity level and potentially
increased abdominal pressure (obesity) should
be taken into account in selecting the opening
pressure level for the gravitational unit.

The selected pressure level of differential pres-
sure unit should always be monitored using the
proGAV 2.0 Compass or the M.blue plus Com-
pass, but it can also be checked with the aid of
an X-ray image (Fig. 5).

The rotor setting is decisive in this case. The
four magnets in the rotor appear in the X-ray
image as white dots and are located opposite
each other in pairs. On one side of the rotor, two
additional burr holes (right and left next to the
magnet pairs) serve as orientation. They appear
as black dots in the X-ray image. This side can
be described as the rear side of the rotor. The
two front magnets are on the opposite side.

The space between these two magnets can
be considered as the apex of the triangle. The
pressure level can be read o using the orien-
tation of this intermediate space (Fig. 6). The
apex of the triangle can take up any posi-
tion except the space marked as a the non-
