What's CSM

What's CSM?
 

CSM is a new small handheld electroencephalogram (EEG) monitor for determining depth and trend of anaesthesia. It can be used together with patient monitor, anesthesia delivery system, ceiling supply unit, etc. Stand-alone operation is also available.

The cerebral state monitor can offer you the following benefits
 

1. Quantitative assessment of consciousness
2. Optimal surgical condition determining
3. Shorter recovery time
3. Less drug usage
4. Lower surgery cost

Features
 

1. Multi-parameter EEG waveform is displayed.
2. CSM Link Software™ for case documentation.
3. Cerebral State Index (CSI) of 0-100 is displayed on all screens.
4. Rechargeable battery operation is available.
