iVAPS Technology (intelligent Volume-Assured Pressure Support)
For hypercapnic, hypoventilating patients
iVAPS is intelligent air
iVAPS is ResMed’s intelligent Volume-Assured Pressure Support,
a unique technology that simplifies the process of ensuring appropriate
ventilation for the patient and reduces the need for frequent
adjustments to therapy over time.
The iVAPS advantage
Intelligent.
Unlike other ventilation modes that only target tidal volume, iVAPS targets
alveolar ventilation, accounting for anatomical dead space to ventilate the
patient more effectively. iVAPS provides an intelligent Backup Rate (iBR)
when necessary while maximizing the patient’s opportunity to
spontaneously trigger the device.
Personalized.
The Learn Targets feature learns the patient’s alveolar ventilation and then sets
targets accordingly, giving you a simpler, time-saving option to set up NIV patients.
Whether you choose this feature or prefer to set targets directly, iVAPS makes it easy
to customize therapy for each patient (Learn Targets not available on S9 VPAP Tx).
Automatic.
iVAPS automatically adjusts the level of pressure support to achieve
and maintain the target alveolar ventilation while minimizing sleep disruption.
iVAPS is suitable for adults with respiratory insufficiency
conditions, including:
Neuromuscular disease and restrictive conditions
iVAPS can maintain stable ventilation when respiratory effort
fluctuates, especially during sleep.
Chronic obstructive pulmonary disease (COPD)
iVAPS may reduce the risk of hyperinflation associated with
increased respiratory rate, as compared to therapy targeting
tidal volume.
Obesity hypoventilation
When compared to standard pressure support therapy, iVAPS
can compensate for changes in respiratory mechanics, such
as during nocturnal position changes.
Notes:
Ensure Ti Max, Ti Min, Rise Time, Trigger and Cycle are set
appropriately to maintain patient–device synchrony.
Please reference the attached TiControl

guide for correlating
Ti Max/Ti Min settings appropriate for each disease state and
adjust based on patient’s respiratory rate.
