Glossary
User’s Manual
G-3
Fraction of Inspired Oxygen (FIO
2
)
Amount of oxygen delivered to the patient.
FIO
2
Sensor
The sensor which measures the amount of oxygen being delivered to the patient.
Flow
Volume of gas delivered by the ventilator compared to time, expressed in litres per minute (lpm).
Flow Pattern (Ramp Setting)
This is the flow distribution shape during the inspiration phase. There are three flow patterns
available: Square waveform or constant flow, Decelerated (sawtooth waveform) or decreasing flow
and Sinusoidal flow.
Freeze
Interruption of the waveform plot tracing on the ventilator’s display.
hPa
An abbreviation for “hectopascal“ which is a unit of measure for atmospheric pressure.
I:E ratio
Inspiratory time versus exhalation time ratio.
Inspiratory Phase
Phase of the breath cycle during which the patient inspires.
Inspiratory Sensitivity (I Sens)
Level of inspiratory effort the patient has to provide during the initiation of a machine breath. The
sensitivity levels (from 1P to 5) correspond to differences in flow compared to the bias flow. Level
1P is the most sensitive (for a pediatric use) and requires the least effort to trigger a breath. Level 5
requires the most amount of effort to trigger a breath.
Inspiratory Tidal Volume (VTI)
Volume delivered to the patient at each inspiratory phase.
I Time (Inspiratory Time)
Inspiratory time measure.
Intentional Vent Stop Alarm
Intentional Ventilation Stop Alarm - Ventilation has been switched off by the user / caregiver and
the ventilator is in stand-by.
I/T Ratio
Inspiratory time versus total breath time ratio.
L
litres (a unit of volume).
Leak
When ventilating with a double limb circuit in leak configuration, it is the average unexpected leak
during each cycle and over the past 24 hour period. When ventilating with a single limb circuit
there is no average leak.
