This manual is intended to assist the user in operating the Cerebral State Monitor (CSM) in a safe and effective manner. This version of the manual was originally drafted, approved and supplied by Danmeter A/S in English. Before operating the monitor read this manual thoroughly, with particular attention to all warnings and cautions.
List of Symbols Type BF equipment On / Off Attention, consult accompanying documents Do not dispose of in refuse collection. Dispose of at a recycling station or equivalent in accordance with directive 2002-96-EC WEEE. Installation and Preparation The Cerebral State Monitor system CSM007 includes the following: Cerebral State Monitor CSM Wireless Link Patient Cable...
Skin Preparation and Sensor Positioning To ensure low sensor impedance, clean skin with mild soap and water is recommended as a skin cleanser. Note: Alcohol is not recommended as a skin cleanser; it leaves a film layer that may cause high sensor impedance.

Operation Display Modes The CSM always starts with display A Switch between display A, B, C, D and E by pressing the Display key (7). Display Mode D CSI trend histogram with 5-minute interval showing average, lowest and highest CSI values within the interval. EMG% is displayed as a bar in the right panel Display Mode C CSI trend curve with event markers and BS curve.

The EEG waveform derives from the signal recorded between the frontal and mastoid electrodes. The frequency content is 2-35 Hz. If the EEG amplitude is low then in some conditions the ECG might be detectable in the EEG waveform EMG% is shown in the display as a bar in the right-hand side. Operating time and numerical value for current CSI and BS%.

CSM Parameters BS% Indicator The amount of Burst Suppression (very low-amplitude or “flat” EEG) is displayed in all Display Modes at the top left hand side. Please refer to Section 5.5 for further information on the BS% measurement. EMG% and EMG bar The EMG level is displayed either as a numerical percentage (0-100%) value in Display Mode A or graphically as a bar at the right hand side in Display Mode B.

Principle of Operation High Quality Amplifier An instrumentation amplifier collects ongoing EEG with a high Common Mode Rejection Ratio ensuring a high-quality EEG acquisition. Special artifact detection algorithms are used to eliminate their effects on subsequent CSI calculations. Measurement Principle The performance of the CSM is based on the analysis of the frequency content of the EEG signal.
CSI Scale The CSI is a unit-less scale from 0 to 100, where 0 indicates a flat EEG and 100 indicates EEG activity corresponding to the awake state. The range of adequate anesthesia is designed to be between 40 and 60. All values in the table are approximate values based on the mean values of the patient behaviour.
High levels of facial muscular or electromyographic (EMG) activity can interfere with the CSI under certain circumstances. The monitor incorporates an EMG filter that removes most of the potential interfering EMG activity. The EMG bar shows the energy of the EMG level in the 75–85 Hz frequency band (0–100 logarithmic).
CSM Battery / CSM Power Operation Using CSM Power and CSM Rechargeable Batteries The CSM can be operated in two different modes • Battery operated • CSM Power operated Warning: Only standard CSM rechargeable battery CSMX04 or alkaline batteries must be used.

Connecting CSM Monitor and CSM Link Turn on the CSM Link. Power indicator shows a constant light. Link indicator is off. Turn on the CSM monitor. The CSM monitor shows a list of CSM Links found. Select CSM Link ID (Serial No.) with the Event key (8) and the indicator Link flashes, or choose skip in order not to establish a connection.

11 Troubleshooting • CSM does not turn on when power key is pressed? Change to a new battery or a fully recharged battery. If changing the battery does not help, send the CSM for service. • Rechargeable Battery seems to have a diminished user time 1.

• CSI is higher than expected Check anesthetic delivery systems: IV lines and status of vaporizers. Some patients require a higher dose of drugs due to interpatient variability. Adequate dosing for maintenance may not be sufficient for increased stimulation. • CSI rises along with EMG High levels of facial muscular or electromyographic (EMG) activity can elevate the CSI under certain circumstances.
12 System and Error Messages For error codes (1-10 and 14) shown in the display, contact the appropriate service or distribution center. See section 14. Together with the error code an audible alarm is activated. Error codes 11, 12 and 13 can occur if the patient cable or the electrodes are connected while the CSM is performing the start up check.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the CSM Is used exceeds the applicable RF compliance level above, the CSM should be observed to verify normal operation, If abnormal performance is observed, additional measures may be necessary, such as reorienting or...
