Min/Max PS
The default settings for maximum and minimum pressure support are normally adequate, but
you may wish to alter them in some patients.
Min PS and Max PS define the range of pressure support adjustment available to the iVAPS
algorithm as it regulates alveolar ventilation.
It is recommended that Max PS be set high enough to allow the alveolar ventilation target to be
met, while exercising clinical judgement over considerations such as patient comfort and
tolerance, lung mechanics, age, mask seal, etc.
It is recommended that Min PS is left at the level set when learning the patient's ventilation
