1 Safety-related information
Prior to using the MPR2 logO, please attentively read the entire instructions for use and familiarise
yourself with the operation of the appliance.
Prevent longer direct skin contact between patient and housing of the MPR2 logO.
In order to ensure safety, reliability and performance of the system, the following notes shall have to be
observed carefully:
Changes and modifications of the unit are not permitted.
•The MPR2 logO (hereinafter referred to as MPR2 for short) may be operated by qualified staff only.
•The MPR2 may be operated only with the specified mains power adapter, see chapter 11.1 Technical
data.
•Select only such wall outlet for the mains power adapter that is accessible to the user without difficulty.
Do not place the mains power adapter in a way that makes it difficult to disconnect the adapter from
the wall outlet.
•The mains power adapter is a part of the medical device. To completely disconnect the MPR2 from the
mains, disconnect the mains power adapter from the wall outlet.
•Prior to using the MPR2, you have to be completely familiar with the operation of the system.
•The MPR2 may be used on one patient at a time only.
•No splitting into spatially separate sensors for pressure and temperature may be effected at the multi-
purpose port P2/T2.
•When monitoring vital functions, a redundancy of the measuring functions is required. In this respect
the pO2 channel is a special feature. A real redundancy cannot be effected in the MPR2. However,
through the evaluation of the intensity of the optical receiving signal and the monitoring of the reference
LED, a far-reaching monitoring has been ensured.
•When the apparatus is switched on, a signal is sounded which is intended to check the alarm sounding
unit. If the signal is not sounded, the apparatus must not be used.
•If two or more apparatuses with separate mains connections are used on the same patient, the
apparatus leakage current adds up which may cause a potential hazard. In this case, use shall be
permitted only, if it has been secured that patient and operator are safe, and that the requirements of
standard IEC 60601-1 are fulfilled.
•Every person who connects an additional unit to the signal input or signal output configures a medical
system, and thus he / she shall be responsible for the fact that this system meets the requirements of
standard IEC 60601-1.
•Simultaneous operation with other apparatuses connected to the patient may cause mutual influences
which may have an effect on the measuring results.
•Note that in the event of different alarm pre-settings for the same or similar devices, which are used in
different hospital areas (e.g. ITS or the operating suite), the interchanging of settings can cause a
potential danger to patients. Therefore always check that the alarm settings are suitable for the patients
concerned prior to starting monitoring. (s. chapter 4.3 Selecting the limiting alarm values)
•The unit can forward up to two pressure signals to a downstream redundant monitoring system. By
means of the downstream system, it is possible to easily integrate the datalogger into a central
monitoring system. In the process special attention has to be given to the fact that only approved
systems from the listed accessories are connected. In case of every signal relaying, proceed as
rendered in the instructions for use of the MPR2: Establish the cable connection; check the signal
transmission; and set the alarm limits to the foreign system.

•Prior to using the MPR2, the correct condition of the apparatus and any accessories shall have to be
checked. Check the plausibility of the readings before using the apparatus for monitoring. The
apparatus and the accessories must not be damaged or soiled; otherwise the apparatus must not be
used. Do not use the apparatus, if it reveals obvious signs of a wrong function; in this case forward the
unit to the after-sales service of the manufacturer.
•In questions of servicing, please always get in touch with the manufacturer. The manufacturer will give
you a list of authorised service partners, if and when required.
•In all fastening and erection variants, please make sure that the apparatus cannot drop or cause other
hazards. Please also ensure a safe laying of the cables so that a tipping over of the arrangement is
prevented.
•Do not use the apparatus in potentially explosive surroundings. The apparatus shall have to be set up
at a minimum distance of 25 cm to any anaesthesia units and gas filled hoses.
•After use the accessories shall have to be cleaned, disinfected or sterilised in keeping with the
instructions for use. If the accessory has been provided with separate instructions for use, the
instructions rendered there shall be applicable.
•If the apparatus has been taken from colder into warmer surroundings, it may be used only when the
temperature of the apparatus and of the accessories has adapted to the room temperature; there is no
danger of condensation water forming or any condensation water already developed has completely
dried.
•Please also observe the safety instructions in conjunction with the use of sensors and transducers
which have been included to the respective sections of the instructions for use.
•No liquids or fluids shall enter the apparatus. If this should happen nonetheless, first remove the mains
adapter from the port. Hand over the apparatus to the after-sales service department for inspection.
Subsequently a safety-related check is necessary.
•The MPR2 has been designed in conformity with standard IEC 60601-1. It is a product of class of
protection II with an internal power source and an external mains adapter, and has been allocated to
class IIb (MPG).
•If sterile accessories are used, please make sure that they are marked as being sterile.
•If the apparatus is subjected to strong electro-magnetic fields, please observe that the pressure display
may vary by up to 2 mmHg. For this reason, avoid using mobile phones, therapeutical microwave
devices or similar units in the vicinity of the apparatus.
•The following instructions shall have to be observed for the installation of the system (with laptop and/or
foreign unit – monitor):
•Moveable multiple sockets must not lay on the floor.
•Additional moveable multiple sockets or extension cables must not be connected up to the system.
•Apparatuses, which are not part of the system, must not be connected.

2 Description of the device
2.1 Intended purpose
2.1.1 Description
The MPR2 is used to monitor the oxygen partial pressure, to monitor up to two invasively measured
physiological pressures, and to monitor of up to two temperatures of the patient (with alarm function).
2.1.2 Intended use
The MPR2 is a diagnostic unit with physiological threshold value monitoring and display of the following
physiological parameters: invasive pressure (ICP, IBP, two channels), oxygen partial pressure (pO2, one
channel) and temperature (T, two channels). Invasive pressure measurement, oxygen partial pressure
measurement and temperature measurement are significant performance characteristics of the unit. These
parameters are determined by using RAUMEDIC catheters for single-channel ICP measurement or with
RAUMEDIC multi-parameter catheters for combined measurement of ICP and temperature. In addition,
external transducers may also be used for the invasive pressure measurement. Optionally up to two
pressure signals can be passed on through the two analogue outputs to a bed-side monitoring device with
threshold monitoring.
2.1.3 Operational environment
The MPR2 is intended for use in clinical environments to be operated by specialized medical staff. The unit
is used either stationary or mobile during transport in the hospital. Doctors, intensive care nurses and
