that's Spontaneous/Timed and Adaptive Servo Ventilation.

It is interesting to me that PR lists their ST machine and their APV machine in completely different categories.
well, if one were to go by resmed's titration protocol guide, the ST is indicated for:
• Neuromuscular/restrictive disorders
• COPD
• Obesity hypoventilation
and the adapt (asv, not APV) is indicated for:
• Periodic breathing, both normocapnic and hypocapnic
• Other forms of central and concomitant obstructive events (mixed sleep apnea)
• Complex sleep apnea (CompSA)
so, two rather different target audiences.
the ST machines don't have the programming to respond, breath by breath, with varying levels of pressure to act as a regular cpap when you're breathing by yourself, but then increase, or decrease, the level of ipap on a per breath, as needed level to make up for the waxing and waining that is characteristic of cheyne stokes respiration, for instance.
