MANUAL MANDATORY BREATH
A manual mandatory breath at the currently set parameters may be delivered at
any time by pressing the Manual Breath button on the keypad. If this function is
pressed during inspiration or during the minimum exhalation time, the ventilator
waits and delivers the manual breath at the end of the minimum exhalation time.
Figure 168: Delivery of Manual Breath
This breath type may be delivered in all ventilation modes.
In the CPAP/PSV ventilation mode, where there is no definition for machine
breath, the Manual breath is set according to the default volume control for the
specified patient weight.
PATIENT PRESSURE SUPPORT BREATH
A patient pressure support breath is a positive pressure patient breath in which
the ventilator maintains an elevated target pressure during inspiration. The
Pressure Support setting is a pressure above PEEP when PEEP is in use. Pressure
Support breaths are always initiated and terminated by the patient and
controlled by the ventilator. When the patient initiates a pressure support breath,
the ventilator raises the inspiratory flow to meet the patient’s demand at the
airway pressure set level.
The termination of a pressure support breath occurs when:
 The flow decreases to a set value of the peak flow (esens); or
 The airway pressure exceeds a value 5 cmH2O above target pressure; or
 After three seconds.
