Description

 

HC

Humidity Compensation (HC) algorithm

 

 

Invasive mode, compensation range is 0.0 to 3.0 °C ( CSP = 37.0 to 40 °C )

 

 

Non-Invasive mode, compensation range is 0.0 to 5.0 °C ( CSP = 31.0 to 36.0 °C )

 

 

By pressing the Mute and Mode buttons together for 1 second or pressing the Mute

 

and Power buttons together for 1 second the user can respectively move up or

 

 

down through the settings listed below. The humidifier will confirm the change with

 

a double-beep.

 

 

‘5.0’ = +5.0 °C of chamber compensation (Non-Invasive mode only)

 

 

‘4.0’ = +4.0 °C of chamber compensation (Non-Invasive mode only)

 

 

‘3.0’ = +3.0 °C of chamber compensation

 

 

‘2.0’ = +2.0 °C of chamber compensation

 

 

‘1.0’ = +1.0 °C of chamber compensation

 

 

‘0.0’ = +0.0 °C of chamber compensation (No compensation)

 

 

‘-A-‘ = Automatic humidity compensation mode:

 

 

 

Invasive mode: 0 to 3 °C in 0.5 °C steps

 

 

 

Non-invasive mode: 0 to 5 °C in 1 °C steps

 

CSP

Chamber set point, in 0.1 °C resolution eg: 37.0

 

 

Invasive mode range 35.5 to 40 °C.

 

 

Non-Invasive mode range 31.0 to 36.0 °C.

 

Cdc

Chamber Duty Cycle (%)

 

CHP

Chamber Power / Flow ratio (W/LPM)

 

 

 

 

hP

Heater Plate Temperature (1 °C)

 

Flo

Gas Flow Rate (0.1 LPM)

 

 

“---“ = Unknown Flow (flow measurement not started)

 

FLr

Gas Flow Rate Range:

 

 

“---“ = Unknown Flow (flow measurement not started)

 

 

“no” = No flow

 

 

“Lo” = Low flow, ( < 3 LPM )

 

 

“In”

= Intermediate flow, ( 2 to 17 LPM )

 

 

“Hi”

= High flow, ( > 13 LPM )

 

 

“ -“

= Ventilated flow detected

 

ASP

Airway temperature set point (0.1 °C)

 

 

 

 

Adc

Airway Duty Cycle (%)

 

Cct

Connected Circuit heater identification:

 

 

“S“ = Standard inspiratory heater connected

 

 

“C” = Coaxial inspiratory heater connected

 

 

“E” = Expiratory heater connected

 

 

“---” = No heaters connected

 

LAS

Last Alarm State, the display will blank, and the humidifier’s last alarm will be shown

 

on the indicators. To clear LAS, press and hold the mute and mode buttons for 1

 

 

second. The humidifier will beep when LAS has been cleared.

 

LFS

Last Fault State, refer to section 6.3. To clear LFS, press and hold the mute and

 

 

mode buttons for 1 second. The humidifier will beep when LFS has been cleared.

 

SoF

Software version

 

End

Press the mute button to cycle to the start of the menu, or the diagnostic menu will

 

 

automatically exit after 6 seconds
