What does ASV stand for in the context of sleep therapy?

Adaptive servo-ventilation (ASV) is a form of positive airway pressure therapy specifically designed for patients with central sleep apnea, mixed apnea, or complex sleep apnea. This therapy adjusts pressure levels dynamically in response to the patient's breathing patterns throughout the night. Unlike traditional CPAP therapy, which delivers a continuous pressure regardless of the individual's need, ASV personalizes the treatment by continuously monitoring both the patient's breathing and airflow. This allows ASV to provide support when respiration is insufficient and to decrease pressure when the patient's breathing stabilizes, thereby aiding in the restoration of normal respiratory patterns during sleep.

The other options do not accurately reflect the purpose or function of ASV in sleep therapy. For instance, "automatic sleep ventilation" does not specifically address the targeted adaptations of pressure that ASV provides. "Assisted sleep ventilation" suggests a more passive role in supporting breathing without the nuanced adjustments characteristic of ASV therapy. "Advanced sleep ventilation" lacks specificity and does not align with established terminology used in the context of sleep apnea treatment.
