Probes must be properly placed in the probe retainer. • Activate scanner and scan barcode labels • Connect probe heads to BMU Sensor and/or BMU Cell • Start perfusion by pressing the ”Go online” button

3. Scope of delivery: • Monitor incl. venous and arterial probe heads • User manual and main power cable • Positive end test protocol • USB memory stick • Holder incl. adpater plate and screws, if ordered • Transport case, printer, and other accessories come separately

4. External devices: • Connect external devices such as printer, OR computer, or heart-lung machine according to the user manual • Printer must be in a distance of at least 1.5m from the operating table • External devices on the serial ports of the BMU 40 must comply with IEC 60950, IEC 60601-1, and IEC 60601-1-2 in case they are standing within a range of 1.5m or less away from the operating table • External devices on the serial ports of the BMU 40 must comply with IEC 60601-1, IEC 60601-1-1, and IEC 60601-1-2 in case they are standing within a range of 1.5m or less away from the BMU 40

5. Assembling the holder: • Fasten adapter plate on the back of the BMU 40 • 2. Attach holder arm on the adapter plate

6. RS-232 (input/output) RS-232 (input/output) USB for printer Power supply Fuse Grounding pin Check connections:

7. Connecting and initialising the probe heads: • Before you switch on the BMU 40, make sure that the probe heads are connected properly to the pobe head holder. • First hook it in on the lower end and then click the nose into the probehead.

8. Initialising the probe heads: • After successful initialisation of the probe heads, the starting screen appears.

9. Calibrating the unit: • Enable Scanner • Hold the barcode label in front of the scanner at a distance of 20 – 30 cm • Connect probe heads to BMU Sensor and BMU Cell

10. Correct probe-cuvette connection: • First hook in the probe head on one side and then click the plastic nose into the probe head on the other side • Make sure that the connection is correct • Please note: Incorrect probe-cuvette-connections may lead to invalid measurement data!

11. Starting perfusion: • When barcode labels are scanned and the probe heads are connected perfusion can be started • Press the ”Go online” button on the touch screen

21. For disinfection the following cleaning supplies are successfully tested and can be used: • Alcohol (Ethanol, Isopropanol) • Cidex OPA (J&J) • Pursept (Merz) • PeraSafe (PAA)

22. General details: • BMU 40 is only to be used by medical staff who is qualified accordingly • Before initial operation read the user manual • Keep the unit connected to power supply to ensure that the battery is always fully charged • The user is responsible that the clinical environment complies with the limits specified in IEC60601-1-2 • Switch off the unit during storage, maintenance, repairing, and cleaning • Maintenance and reparation can only be performed by the authorised MAQUET service

23. Potential influence on measurement results Optical SvO2 measurement methods can be influenced by • Methylene blue • Indocyanine green • Evans Blue • Fetal hemoglobin and unusual levels of • Bilirubin • Lipids • Beta Carotine • Carboxyhemoglobin • Methemoglobin • Sulfhemoglobin

24. Influence on measurement results Hb/Hct measurement can be influenced by • Sickle cell anemia • Macrocytic anemia • Hyperlipidemia

25. Sensors, cells, and probes: • Sensors and cells must not be cleaned with alcohol, aether, or acetone • Avoid fingerprints on cells and sensors • Sensors and cells have to be disposed after use and must not be used twice • Each sensor and cell has a unique barcode which can only be used one time. The system denies any barcode which had already been used • To clean the probes, use only water and a soft non scratching tissue • Avoid scratches on the probes • Don’t use chemical cleaning supplies to clean the sensor surfaces of the probes
