How does adaptive-servo ventilation (ASV) compare to a continuous positive airway pressure machine (CPAP)?

ANSWER

These are the main differences between ASC ASV and CPAP:

?ASV pressure adjusts to your breathing as it changes during sleep. CPAP air pressure is constant.

?ASVs are better for treating complex sleep apnea.

?ASV units are more expensive than CPAPs.

?Many people stop using CPAPs because they�re uncomfortable. ASVs are easier to wear and quickly relieve symptoms. This may make you more likely to stick to using your ASV if you�ve given up on a CPAP in the past.
