Introduction The System M Monitoring System from Spectrum Medical can be configured to measure a wide range of critical parameters both non-invasively and in real-time with in an extracorporeal circuit. The System M Monitoring System has been designed to be use by experienced and trained clinicians as part of a diagnostic process. The device is not intended to be used by the patient or other untrained personnel.
Intended Use M2
The M2 is configured to measure arterial and venous saturation, hemoglobin and a calculated hematocrit.
M3
The M3 is configured to measure arterial and venous saturation, hemoglobin and a calculated hematocrit concentration, multiple blood flows and gaseous emboli.
M4
The M4 is configured to measure arterial and venous saturation, hemoglobin, calculated hematocrit concentration and multiple blood flows, gaseous emboli, predicted PO2, predicted PCO2, FeCO2, FiCO2, FiO2, gas flow and Temperature.
VIPER DM
The Viper DM is a platform for running Viper Independent Data Management software which has no measurement capability.
The device provides monitoring information to trained clinicians and can be configured by them to set parameter specific alarms. The device has a monitoring and alarm function only; it does not directly control patient treatment nor sustain life. The user may make clinical judgements regarding the treatment of the patient as a result of information displayed by the device. Caution 1: Federal (US) law restricts this device to sale by or on the order of a physician. Caution 2: Failure to follow the instructions for use can cause the monitoring system to display inaccurate values. The accuracy of the results is dependent upon the following:
Reading and understanding the instructions for use Proper set-up of the device Use of all available system features Periodic comparison and synchronisation to a laboratory reference sample The gas module can use a supplied blood temperature and / or blood flow rate, the user needs to supply an ‘actual’ temperature for accuracy of results.
When a displayed value is significantly different from expectations, verification of results with laboratory analysis is recommended prior to initiating treatment.

Important Note:
Principles of Measurements
The Measurement of SaO2 and SvO2 The measurement of O2 saturation is achieved by analysing a specific region of the oxy-haemoglobin curve using 100 discrete wavelengths of light. The use of this non-invasive optical recognition technology ensures that the O2 Saturation measurement is highly accurate and extremely repeatable. A single synchronization with a reference blood gas system is all that is required. The measurement is independent of blood flow, blood temperature and blood dilution.
The measurement of Hemoglobin and calculated Hematocrit: Infrared light from an LED passes through a flowing tube of blood. A photodiode detects a receiving light level and converts the resultant light energy into a proportional electrical output. The sensors are pre-calibrated using a traceable reference. A software algorithm linearizes this relationship and converts the incoming signal to an actual reading of Hemoglobin and a calculated Hematocrit. Warning:
Only synchronize the M2 technology with a calibrated Blood Gas Analyser.
Do not synchronize with third party inline monitors as this will lead to inconsistent accuracy.
The measurement of blood flow rate and emboli Ultrasonic emitters and receivers are placed such that the energy is passed through the tube of blood. By monitoring the transmitted and received signals, the software is capable of determining flow rate and direction using phase variations. The sensing hardware is calibrated to a master flow meter using a traditional two point calibration for accurate results. Emboli are detected using the same sensing hardware but uses signal strength to determine the volume of emboli passing between the sensor emitters and receivers. The hardware is capable of very high speed sampling to ensure accuracy. The speed of the fluid flow and sensor size is taken into account when estimating emboli volume.
Gas module measurements FiO2 is measured using a galvanic cell to generate voltage from oxygen. CO2 is measured using an optical sensor. Gas flow rate is measured by detecting pressure drop across a fixed orifice using a delta P strain gauge transducer. Gas pressure is measured using an atmospheric pressure sensor that uses strain gauge technology. Blood temperature is measured using a thermistor sensor. PO2 and PCO2 are predicted results based upon a software algorithm that makes use of Blood Temperature, Blood flow rate, FiO2, FeCO2, FiCO2 and Gas Pressure. Both 37ºC and/or body temperature results can be displayed. Warning:
Date:19-Dec-16
Significant changes in blood temperature (greater than 12oC) may affect the accuracy of PO2 and PCO2 and therefore synchronisation with a laboratory reference sample may be required.

Safety Instructions Not to be used internally or in a sterile environment. The use of the monitor is restricted to one patient at a time. The equipment is designed to be used only when continuously attended by a clinical operator. Information from still or slow flowing blood may not be valid.
Do not cover the fan or ventilation holes when the monitor is in use or insert foreign objects into the memory card socket. Before connecting the monitor to a power source, ensure the voltage rating of the power supply matches that of the available power source.
The fibre optic sensor cable must at all times be handled with care. Do not exceed the minimum bend radius of 50 mm.
To avoid the risk of electric shock, the monitor must only be connected to a supply mains with a protective earth (ground). Use only the Spectrum Medical supplied IEC 60320 mains cable. Make sure the cable is located where it cannot be tripped over and nothing rests on it.
Do not touch any part of the monitor and the patient simultaneously.
Only use the IEC60601-1 approved power supply supplied with the monitor (Part No: PMP90-11-K17).
Do not connect the monitor to any equipment other than that approved by, or supplied by Spectrum Medical.
Ensure sensors are connected to the blood pipes when monitoring and avoid using in strong ambient light.
Sensors should only be connected to blood pipes that are clean and free of dust and/or manufacturers’ markings.
Do not use with silicone tubing.
To avoid the risk of eye injury, do not stare directly into the sensor LEDs. It is recommended that an anti-bacterial filter is placed between the Gas Measurement Module and the Oxygenator. The monitor requires no special precautions to be taken to protect the patient or operator during defibrillation and the normal operation will resume at most 15 seconds after defibrillation.
The monitor will emit low levels of electromagnetic radiation when Wifi communications are in use. The System M contains no user serviceable parts, do not attempt to disassemble the device, contact Spectrum Medical product support for assistance The product is supplied with an Ethernet isolation device, this must be connected to the Ethernet port before connecting a network cable to the product. This device protects the equipment and user from electric shock faults from third party equipment.
Ensure that the monitor is positioned where it cannot be touched by the patient. No special precautions need to be taken when using High Frequency surgical equipment. All sensors are isolated however we recommend all sensors and connections should be positioned to avoid contact with the patient and operator. Do not use the monitor in close proximity to magnetic fields (e.g. MRI scanners), sources of ionizing radiation or near wet environments such as baths or sinks.

6. Making Sensor Connections to the PVC Extracorporeal Circuit. 6.1 Venous SO2 Sensor Note: For sensor and clip sizes see “Sensor Specifications” on page 33. Ensure the tubing size matched the sensor size.
Insert the sensor between the retention hooks until the sensor is secure. Ensure that both the blood tube and sensor assembly are free from dust and any form of contamination. To remove the sensor hold the blood pipe as shown and squeeze the retention hooks until sensor is released.
Attach the required size of pipe clip to the blood pipe. Ensure the retention clips are fully engaged
Warning:
Do not try to pull the sensor free with the fibre optic or coloured strain relief. To avoid causing damage always hold the sensor by the black coloured housing.
6.2 Arterial SO2 / Hct Sensor Ensure that both the blood tube and sensor assembly are free from dust and any form of contamination. Open lid and slide the blood tube into the sensor.
Warning:
Do not use any lubricants on the HCT/S02 sensor except Isopropyl Alcohol wipes to clean. Ensure the magnetic lid of sensor does not interfere with devices in close proximity. Flow and hematocrit sensor calibration is determined by tubing dimensions. Use on tubing other than specified generally yields inaccurate measurements and may cause erratic zero baseline drift.
6.3 Flow Sensor (M3 and M4 Monitors only) Ensure the sensor is free of dirt and contamination. Ensure the sensor is positioned with the arrow in the direction of flow.
Warning:

6.4 Gas Measurement System (M4 Monitors Only) Mount the gas measurement module using the pole clamp in the orientation shown. Use flexible gas tubing to connect the gas supply from the gas blender to the gas measurement module. Also use flexible gas tubing to connect from the gas measurement module to the oxygenator gas inlet port. Position the Gas Measurement Module between the Gas Blender and the Oxygenator. It is recommended that an anti- bacterial filter is positioned between the Gas Measurement Module and the Oxygenator. To Oxygenator Adjuster Knob Connect to oxygenator gas outlet port
From blender
For electrical connections, see section 3.
If the optional support arm is being used, attach the arm to a suitable pole. Then clamp the sensor by gently tightening the lever. By loosening the adjuster knob (pictured Left) will allow all joints to become loose. Manoeuvre the sensor into position such that the tube indicated in the picture left attaches to the oxygenator exhaust port. Once a good position is found tighten the adjuster knob and the assembly will become rigid. Sensor outlet port (Connect gas scavenger line here)
Position the exit CO2 near the oxygenator gas exit port and use a flexible tube to connect the exit CO2 sensor to the oxygenator gas outlet port. Try to maintain a slight gradient in the tube such that the sensor is lower than the oxygenator exhaust port, this will enable any water to run through the sensor. However keep the sensor electrical cables pointing upwards (as shown in picture above) to stop water condensation from entering the sensor. If a gas scavenge line is to be used the scavenge line should be vented and attached to the exhaust sensor outlet port.
Warning: The prediction of PO2 and PCO2 by the M4 will remain within specified levels of accuracy providing re-synchronization with an arterial blood gas sample occurs on a regular basis i.e. 24 hours or less due to changes in oxygenator efficiencies. Ensure the gas module and exhaust sensor are mounted as shown in the above pictures. After use, purge the gas flow airline with air to prolong servicing intervals. The gas module has been design to operate with Air, Oxygen, Nitrogen, CO 2, and the Anaesthetic gases Sevoflurane, Isoflurane and Desflurane. Do not block nor restrict the sensor outlet port under any circumstances. The gas module should not be pressure tested by any other means other than by using the Spectrum Pressure Test Kit (3003-030-101)
