ResMed Astral™ ventilators offer two different VAPS modes:
• intelligent Volume-Assured Pressure Support (iVAPS™*) uniquely targets minute ventilation
• Pressure Support with Safety Tidal Volume (PS/SVt) targets tidal volume
Both modes have more rapid response rates when compared to competitive modes of ventilation.8
One of the key
differentiators for ResMed NIV algorithms is they allow for pressure support increases on a breath-by-breath basis vs a time
increment. Additionally, iVAPS has been shown to reach a stable state of ventilation in significantly fewer breaths than Phillips
Trilogy.8
In all testing scenarios, iVAPS achieved ventilation stabilization in fewer than 13 breaths, whereas Philips AVAPS
algorithm – with the AVAPS rate set to 5 cm, the fastest available setting9
– took significantly longer at up to 74 breaths.8
