Appendix A: Definitions
Ventilation settings definitions
The available settings will vary with the selection of the ventilation mode. Each mode details the settings
available.
Setting Definition
Apnoea Definition Apnoea Definition sets the type of breath which must be delayed for an apnoea to be
detected.
Apnoea Interval
(T apnoea)
Apnoea Interval (T apnoea) sets the period without breath or spontaneous breath
required for an apnoea to be detected.
Apnoea Response Apnoea Response sets the behaviour of the ventilator when an apnoea is detected.
Circuit Type Circuit Type sets whether a Double limb circuit, Single limb circuit with expiratory valve
or Single limb circuit with intentional leak is in use.
CPAP Continuous Positive Airway Pressure (CPAP) sets the pressure maintained throughout a
spontaneous breath.
Cycle Cycle (also known as Expiratory Trigger) sets the threshold where start of expiration
within a breath is detected.
EPAP Expiratory Positive Airway Pressure (EPAP) sets the pressure to be delivered to the
patient during expiration.
Flow shape Sets the target flow waveform for the delivery of mandatory controlled volume breaths.
Inspiratory duration option
(Insp Duration Option)
Inspiratory duration option (Insp Duration Option) sets whether Inspiration Time (Ti) or
Peak Inspiratory Flow (PIF) is used to configure volume controlled breaths.
Interface type Invasive, mask, or mouthpiece
Interval Sigh interval sets the period between sigh breaths.
IPAP Inspiratory Positive Airway Pressure (IPAP) sets the pressure to be delivered to the
patient during inspiration.
Magnitude Magnitude sets the size of the manual or sigh breath delivered relative to the size of the
normal ventilation breath. Separate magnitude settings are available for configuration of
manual or sigh breaths.
Manual Breath Manual Breath sets whether a manual breath is available for delivery.
Mask Type Mask Type sets the type of mask or in-line vent in use when the circuit type is single
with leak.
Max EPAP Maximum Expiratory Positive Airway Pressure (Max EPAP) sets the maximum pressure to
be delivered to the patient during expiration to maintain upper airway patency.
Max PS Maximum Pressure Support (Max PS) sets the maximum pressure support above EPAP
allowed to achieve the Target Va.
Min EPAP Minimum Expiratory Positive Pressure (Min EPAP) sets the minimum pressure allowed to
be delivered to the patient during expiration to maintain upper airway patency.
The Min EPAP should be set to treat any lower airway condition.
Min PS Minimum Pressure Support (Min PS) sets the minimum pressure support above EPAP
allowed to achieve the Target Va (iVAPS).
P control Pressure control (P control) sets the pressure support above PEEP to be delivered during
inspiration for pressure assisted breaths.
