For use as a voltage output
pins 1 and 6 are connected by a
jumper.
For use as a monitor output the
excitation voltage is fed into the
reference input and the analog
output is scaled down by a resistive
divider.
Data Transmission across
the RS 232 C Interface
The IAP-Monitor responds to single
ASCII bytes:
To the monitor
´A´
´B´
´C´
6: Uref Output (2,5 V)
7: Digital Gnd
8:
9: Analog Gnd.
Response
Mean pressure in ASCII string
format, terminated by
´Carriage Return´.
Mean pressure in binary
format, 1/10 mm Hg resolution,
two´s complement, two
bytes, high byte first.
Instantaneous pressure in
binary format, 1/10 mm Hg
resolution, two´s complement,
two bytes, high byte first. Response
only after new value is
read in (every 10 ms).
The IAP-Monitor and the accompanying catheters are designed for
the measurement of intraabdominal
pressure. The manufacturer accepts
responsibility for the safety,
reliability and performance of the
monitor only if:
-the installation, extensions,
readjustments, modifications and
repairs are performed by
authorized personnel,
-the electric installation of the
room is in accordance with the
national regulations concerning
rooms used for medical
purposes,
-the monitor is used in
accordance with the operating
instructions, and
-the monitor is used with the
approved accessories.

Faults
The air-tightness of the air-pouch
system is checked regularly. If a leak
is detected, the red warning
indicator shows alarm. When the
leak is removed the red warning
indicator disappears and the
measurement is continued. If the
leak has not been removed after
one minute, in addition to the alarm
display a chirp sound is emitted. To
reset the alarm the monitor must be
switched off and on again. The
chirp sound stops after one minute,
unless the monitor has been
switched off before, and the digital
display dissapears. The warning
indicator continues to flash.
If a pressure limit is exceeded during
probe filling the filling process is
interrupted, the digital display
shows ´E1´ and the chirp sound is
emitted. This can happen if the airpouch resists unfolding or if the
tube is clamped. Switching off and
on the monitor resets the system.
Monitor operation
After placement of probe the tube
connector is inserted into the
monitor socket and fastened by a
slight clockwise turn. The soft
material of the connector
guarantees airtightness.
Pressure measurements are started
by switching on the monitor. No
manual zero adjustment or
calibration is required.
If the digital display shows ´E2´ or
´E3´ during operation an internal
fault has been detected. Contact
the service in this case.

Cleaning
After removal of the power cord the
unit can be wiped off with a damp
rag using a common disinfectant.
No liquid whatsoever must be
introduced into the catheter or into
the connector of the monitor.
On the digital display the mean
pressure is shown in mmHg.
During the first ten minutes after
switching on the pulse amplitude
(i.e. systolic pressure minus diastolic
pressure) is additionally displayed
marked by an ´A´.
During this time the mean pressure
is displayed for three seconds, then
the amplitude is displayed for one
second.

Indication and Method
The IAP-Monitor and the catheters
are intended for the monitoring of
intraabdominal pressure in the
stomach.
The air-pouch system consists of a
hollow body connected to a
pressure transducer by tubing. The
pressure transducer, the electronic
hardware, and the device for filling
the air-pouch are integrated in
the IAP-Monitor.
For intraabdominal pressure
measurements the air- pouch is
placed in the stomach of the
patient. The intraabdominal pressure
is transmitted across the thin pouch
wall to the air volume in the pouch
and transformed into an electric
signal by the pressure transducer.
On the digital display the mean
pressure is shown. At the monitor
output both the mean pressure and
the pulsatile signal are available.
