TIPS:
• Volume:
You can set an output volume between 50 ml and 750 ml, in increments of 10 ml.
The ventilator set volume does not correspond to total delivered volume of gas delivered to the lung i.e. tidal
volume. Total delivered volume will include ventilator set volume, entrained air, and supplemental oxygen (if
applicable), and therefore will be higher than the ventilator set volume. For more information see "Potential
Tidal Volumes" on page 152.
NOTE:
Volume levels are not adjusted for altitude. For more information see the "Accessories and
Replacement Parts" on page 133.
• I-Time (Inspiratory Time):
The time over which the selected target volume is delivered.
NOTE:
The actual I-Time may be longer or shorter than set if additional time is required to deliver the set
volume. The actual delivery time may also be longer or shorter than set to maintain a minimum delivered peak
gas flow rate of 8–40 LPM range.
• PEEP (Positive End Expiratory Pressure):
PEEP can be adjusted as per the prescription. PEEP values can be
set from 0–10 cmH
2
O.
• Sensitivity (Trigger Sensitivity):
Specifies the minimum negative pressure threshold necessary to trigger a
delivery. The sensitivity setting, adjustable in increments of 1, ranges from 0–9 or OFF, with 0 being the most
sensitive and 9 being the least sensitive.
NOTE:
Trigger sensitivity can be adjusted by the patient unless it is set to
OFF
in the
Ventilation Settings
screen. For more information, see "Adjusting the Trigger Sensitivity (Patient-Adjustable)" on page 76.
Trigger sensitivity settings vary in a non-linear fashion, with relatively finer resolution at lower settings and
relatively coarser resolution at higher settings.
Trigger sensitivity can be adjusted by both the clinician and the patient. Breaths can be triggered by the
patient or by the ventilator based on the
Ventilation Settings
.
• BR (Breath Rate):
The breath rate per minute determines the minimum quantity of machine breaths delivered.
