Warning: Should the ventilator be in use in a mains power fail situation, the
user must be aware that turning off the ventilator and terminating battery
power will mean that the ventilator cannot be restarted, i.e the ventilator
cannot be started on battery power.
The ventilator can only be restarted once mains power has been restored.
14.1.5 Parameter Memory
The user should be aware that the ventilator will remember user parameter
settings when switching between modes, except when switching between a
ventilatory mode and Ventilation Off. When switching from a ventilatory mode to
Ventilation Off and then back to a ventilatory mode the ventilator will reset all
parameters to the default values. Though when the setting is remembered
between ventilatory modes the parameter title may change. An example is the
CPAP parameter in CPAP mode becomes the PEEP parameter in CMV mode.
14.1.6 BPM or Backup, Measured and Set Parameters
The user needs to be made aware that the BPM Tot in the lung mechanics and
measurement panel is updated every 2 seconds, so it may not correspond
immediately with the set value which is for breaths in one minute.
14.1.7 Tidal Volume Parameter Resolution
The tidal volume parameter control has three different resolutions.
From 2ml to 6ml the parameter increments in 0.2ml steps (Fine resolution).
From 6ml to 100ml the parameter increments in 1ml steps (Standard resolution).
From 100ml to 200ml the parameter increments in 5ml steps (Coarse resolution).
14.1.8 HFO, Mean and Delta P Parameters
In HFO only mode the set values for Mean and Delta P are not displayed in the
parameter control, only the measured values are displayed. The Mean and Delta
P controls do not show the precise set values because they should not be used
as a guide to the resulting proximal pressure. The Mean and Delta P readings are
affected by the dynamic lung characteristics.
14.1.9 Displayed FiO
2
If at any time the user believes that the FiO
2
reading has drifted, the user should
re-calibrate the oxygen sensor. The oxygen sensor can be calibrated from the
services panel. (See “Services Panel” on page 49.)
