15.3.6 Setting the Apnea Alarm Delay
In the [CO2 Setup] menu, select [Apnea Delay] and then select the appropriate setting. The monitor will alarm if the
patient has stopped breathing for longer than the preset apnea time. The [Apnea Delay] of Resp and CO
2
module keeps
consistent with each other.
WARNING
The respiration measurement does not recognize the cause of apneas. It only indicates an alarm if no breath
is detected when a pre-adjusted time has elapsed since the last detected breath. Therefore, it cannot be
used for diagnostic purpose.
15.3.7 Choosing a Time Interval for Peak-Picking
For microstream CO
2
modules, you can select a time interval for picking the highest CO
2
as the EtCO
2
and the lowest as
the FiCO
2
.
In the [CO
2
Setup] menu, select [Max Hold] and toggle between [Single Breath], [10 s], [20 s] and [30 s] (for
microstream CO
2
module only).
[Single Breath]: EtCO
2
and FiCO
2
are calculated for every breath.
[10 s] or [20 s], or [30 s]: EtCO
2
and FiCO
2
are calculated using 10, 20 or 30 seconds of data.
15.3.8 Setting the Flow Rate
For the sidestream CO
2
module, you can change the sampling rate of respiratory gas in the patient’s airway by setting
the flow rate. To set the flow rate, enter the [CO2 Setup] menu and select an appropriate setting from [Flow Rate].
WARNING
Please consider the patient’s actual bearing capability and select the appropriate flow rate when setting the
flow rate.
15.3.9 Setting up the CO
2
Wave
In the [CO
2
Setup] menu, you can:
Select [Wave Type] and toggle between [Draw] and [Fill]:
[Draw]: The CO
2
wave is displayed as a curved line.
[Fill]: The CO
2
wave is displayed as a filled area.
Select [Sweep] and then select the appropriate setting. The faster the wave sweeps, the wider the wave is.
Change the size of the CO
2
waveform by adjusting the wave [Scale].
