EDAN M8 Series User Manual

Patient Monitor User Manual Monitoring CO

(Optional)
- 154 -
The selection of functions available on your monitor depends on your monitor configuration.
Now we introduce you to the functions of each item in CO
2
SETUP submenu.
■ WAVE SCALE: to adjust full scale size of CO
2
waveform display area with LOW or
HIGH selectable. The default value is LOW.
■ BARO PRESS: to set the barometric pressure value. For gaining accurate readings,
you should set this barometric pressure correctly.
■ O
2
COMPENS: to adjust the O
2
compensation concentration as per the selection of the
user. Input the proper O
2
compensate value according to the O
2
concentration of the inhaled gas.
■ N
2
O COMPENS: to adjust the N
2
O compensation concentration as per the selection of
the user. Input the proper N
2
O compensate value according to the N
2
O concentration of the
inhaled gas. Only applicable to EDAN EtCO
2
module.
■ ANE AGENT: to adjust the anaesthetic compensation concentration as per the
selection of the user. The concentration ranges from 0% to 2.0%. Input the proper
concentration value according to the anaesthetic gas concentration of the inhaled gas.
■ BALAN GAS: to balance the gas compensating operations. Select different
compensating types for balancing gas. The compensation types are ROOM AIR, N
2
O and
HELIUM.
■
WATERVAPOR
: determine whether to make watervapor compensate.
Water vapor compensation accounts for the effect of water vapor on the CO
2
IR (Infra-Red)
absorption characteristics. The user may disable this compensation in certain situations.
During normal operation, CO
2
measurements are adjusted mathematically to compensate for
this effect.
The host may choose to disable this compensation when performing dry gas measurements
in which the gas does not contain water vapor.
For EDAN EtCO
2
module, the water vapour compensation is OFF by default.
For Respironics CO
2
module, the water vapor compensation is ON by default and may be
enabled or disabled via a host system command.
■ BTPS: The user may want to choose whether to correct values for gas that is at body
temperature, ambient pressure and is saturated with water vapor (BTPS) or the ambient
temperature and pressure and is dry (ATPD). BTPS compensation (Body Temperature and
Pressure, Saturated) is a user-selectable compensation that accounts for the differences
between the airway sample and “deep lung” CO
2
. Since the intent is to report “deep lung”
CO
2
, where the sample is at 37 ℃ and fully saturated, BTPS compensates for the variance of
water vapor content due to temperature. The BTPS compensation of CO
2
module is on by
default.
■ PUMP RATE: to adjust the pump rate of the air pump in the CO
2
module. 70ml/min
and 100ml/min are selectable, which is only applicable to EDAN EtCO
2
module.
■ COMPENSATE: to perform different compensate operations as per the selection of
the user. The selections are GENERAL, O
2
, N
2
O and ALL. The work conditions for
calculating compensation are shown in the following table. Here is the operation method.
First, select the gas compensation to be used, including general compensation, O
