ESO 2 ICU Ventilator 50 User Manual
APPENDIX 5 Spontaneous Mode and Patient Support Modes
Electronic PEEP does not function in Spontaneous Mode or in any Patient
Support Mode.
Spontaneous Mode
Parameters
The ventilator monitors the following patient parameters:
•
Rate
•
VI:E ratio
•
Pressure
•
Tidal volume
The waveform displays are active, and inspiratory oxygen levels are
measured.
Operating Functions
1. Default values will be displayed in white on a black background if the
ventilator has just been powered ON.
2. Functions
•
No mechanical ventilation or Inspiratory Pause function
•
Patient monitoring
- Airway pressure
- FiO2
- Tidal volume
- Rate
- I:E ratio
- Supply pressure
NOTE: The default trigger level (1) for ventilator support is 1.0 L/min flow.
In some patients this may be too sensitive and provide inaccurate triggering
and also result in a displayed BPM reading (2) that is higher than the actual
rate. Should this occur, the user should reduce the level of sensitivity by
setting a higher trigger value.
3. Apnoea Alarm Mute (Spontaneous mode only)
In spontaneous mode the mute button (3) acts both to silence an existing
apnoea alarm and inhibit new apnoea alarms for a given period.
a) The occurrence of another alarm event will override this feature.
b) The alarm mute time period is selectable (choose from 15, 30, 60,
120, or 180 seconds) through the alarm settings menu, or accessed
by touching the alarm area of the screen.
c) When the alarm mute is selected, the mute period is displayed on
the screen, and count-down starts.
Default setting
To adjust the default setting for the apnoea alarm mute, use the SITE
DEFAULT menu option.
Apnoea alarm trigger
The apnoea alarm will trigger if the patient fails to breathe after 15
seconds.
This setting can not be changed.
Apnoea message display
During the alarm mute period the apnoea alarm message will be
displayed if the alarm has been triggered.
The alarm message will be removed if the patient breathes.
If re-triggered, the alarm message will be displayed again, but the
audible alarm will remain muted if the mute period is still active.
