Warning
• Do not use the accessory if the packaging or the internal accessory is damaged. Return it to the
manufacturer.
• The sidestream sampling line is disposable. It should not be disinfected for reuse or cross-used
by different patients.
• In the long-term use, dust or other substances may lower the air permeability of the filter material in the
sample cell and may block the airway. In this situation, the sampling line must be replaced.
• No routine user calibration required. For mainstream,an airway adapter zero is required when changing to
a different style of airway adapter.
16.3 Co2 Menu
16.3.1 Parameter Setup and Adjustment
Turn the knob to select and press CO2 hot key on the screen to activate "CO2 Setup" menu as shown
below:
Figure 16-4 CO2 Setup Menu
Following functions can be realized via CO2 SETUP menu.
• ALM: select "ON" to enable and store alarm prompt when CO2 parameters have alarms. Select "OFF"
to disable alarm and display beside CO2. The default is "ON".
• ALM LEV: select from HI, MED and LO. Level HIGH represents the most serious alarm, followed by Level
MED and Level LOW with a decrease of seriousness. Change in "ALM LEV" can only affect the
physiological alarm levels of CO2 parameters including EtCO2 upper limit, EtCO2 lower limit, InsCO2
upper limit, AwRR upper limit and AwRR lower limit. The default alarm level is "MED".
• ALM REC: select "ON" to generate output from the recorder ever since CO2 parameter alarm occurs.
The default is "OFF".
• CO2 ALM HI: to adjust the upper alarm limit of EtCO2. If the measuring value is larger than CO2 upper
alarm limit, "CO2 TOO HIGH" appears on the screen. After the measuring value returns to the normal one,
the information disappears.
• CO2 ALM LO: to adjust the lower alarm limit of EtCO2. If the measuring value is smaller than CO2 lower
alarm limit, "CO2 TOO LOW" appears on the screen. After the measuring value returns to the normal one,
the information disappears.
• INS ALM HI: to adjust the upper alarm limit of InsCO2. If the measuring value is larger than InsCO2 upper
alarm limit, "INS TOO HIGH" appears on the screen. After the measuring value returns to the normal one,
the information disappears.
• AWRR ALM HI: to adjust the upper alarm limit of AwRR. If the measuring value is larger than the upper
alarm limit of AwRR, "AWRR TOO HIGH" appears on the screen. After the measuring value returns to the
normal one, the information disappears.
• AWRR ALM LO: to adjust the lower alarm limit of AwRR. If the measuring value is smaller than the lower
alarm limit of AwRR, "AWRR TOO LOW" appears on the screen. After the measuring value returns to the
normal one, the information disappears.
• APNEA ALM: After selecting the alarm time for APNEA alarm (having 7 levels, which are 10S, 15S, 20S,
25S, 30S, 35S, and 40S), the "CO2 APNEA" information will appear on the screen after the corresponding
selected time. The alarm level is HIGH.
• SWEEP: to adjust the display rate of CO2 waveforms with "6.25 mm/s", "12.5 mm/s", or "25.0 mm/s"
selectable.
