2AHYINIRSITBNIRSIT

NS1-H20B General Information i General Information Thank you for purchasing NIRSIT, a near-infrared multi-channel device, made by OBELAB Inc. NIRSIT is a device designed to measure variations in cerebral blood oxygen saturation by radiating a near-infrared light beam, at two wavelengths of 780 nm and 850 nm, into the cerebral cortex. The device radiates a laser with a light output of 1 mW or less. It is harmless to the human body. The device comes with software used to monitor the distribution of cerebral oxygen saturation via multiple channels. NIRSIT is well suited for brain researchers.

Using the NIRSIT Software 47 4.9 Using the Software in Quick Mode In Quick Mode, the NIRSIT software monitors the subject’s cerebral oxygen saturation (rSO2) without an active account. In Quick Mode, rSO2 values are displayed in numeric format and graphical format in real time. To use NIRSIT in Quick Mode, select MENU BAR > SETTINGS and set Quick Mode to On. 4.9.1 Real-time Monitoring On the START TO MEASURE screen, select GO. Using the NIRSIT Software 48 4.9.2 Quick Mode Screen Overview No. Description 1 EVENT items selected from MENU BAR > SETTINGS > Events will be displayed in the EVENT list below. (see 4.7 Configuring Initial NIRSIT Settings) 2 Items pre-defined in EVENT and Setting are shown. Mark an event by selecting on the Event. The selected event marker is displayed on the corresponding time axis in graph format. 3 During initialization (for 30 seconds) after the start of the measurement, the box maintains a green background and the values are displayed as “--.” The background becomes red during measurement if measurement results are deemed incorrect. This may occur when the device is put on the subject incorrectly or the device is exposed to a bright sunlight. 4 The measurement date and duration are displayed. 5 BASE LINE setting button 6 Set values obtained by selecting the basic-value setting (BASELINE) button as basic values. 7 Variations between the current values and the reference values are shown (blue indicates a decrease while red indicates an increase). 8 Left and Right oxygen saturation values (rSO2) are shown. 9 Set the alarm on or off, according to the alarm conditions specified in initial settings. 10 Left and right measurements are displayed in graph format, where x axis denotes measurement time period in minutes. Selected events are displayed with green markers).
