This mode is for patients with a tracheal tube. The preset for the patient side is 40
C and
chamber side is 37
C automatically.
NPPV Mode
: This mode is for patients with NIV (Non Invasive Ventilation) masks. The preset for the patient
side is 34
C and chamber side is 31
C automatically.
MANUAL mode
: This mode allows the selection of optional temperature of both patient side and chamber
side. (Refer to 5 for the details.)
On selecting MANUAL mode, a sound confirmation will be activated and the display will show the set
patient temperature and then the currently set chamber side temperature for approximately 2 seconds each
as confirmation of the initial setting. After 2 seconds, LED

In normal operation the temperature shown in main display (2) is measured from the point indicated by
LED
ⓐ
(patient temperature) or LED
ⓑ
(chamber temperature) whichever is illuminated in green.
2.
On entering manual mode the temperature shown in display (2) will be the patient temperature when
LED
ⓐ
is blinking green and chamber temperature when LED
ⓑ
is blinking. To change temp see section
5
3.
Illuminated LED shows location of the fault, as detailed below.
LED
ⓐ
Patient Temperature
Flashes red
- the measured temperature has exceeded the set temperature by 2
C, or exceeded a
maximum temperature of 43
C (in this case there is a high
priority audible alarm and the heated wire is
turned off).
Flashes red
- Patient Probe temperature has not increased by >2
C in 2 minutes after Power-on
(in this case there is a high priority audible alarm).

C below the set temperature (in this case a medium
priority
audible alarm sounds intermittently).
Note:

- The measured temperature exceeds the set temperature by 4
C for more than 20 minutes,
or the measured temperature exceeds the set level by 10
C (in this case there is a high priority audible
alarm and the heated wire is turned off).
Flashes yellow
– the measured temperature is 4
C below the set temperature for more than 20 minutes, or
the measured temperature is below the set temperature by 10
