adaptive servo-ventilation (ASV)

Indications
- Cheyne-Stokes respirations in patients with heart failure[2][4]
- may be useful in patients with central sleep apnea[6]
Contraindications
- not useful in patients with central sleep apnea & heart failure due to LV systolic dysfunction[1]*
- contraindicated in patients with LVEF < 45%[7]
* ref[5] reports that adaptive servo-ventilation is effective in patients with systolic heart failure without mention of Cheyne-Stokes respirations
Procedure
- uses a noninvasive ventilator by delivering servo-controlled inspiratory pressure support on top of expiratory positive airway pressure[1]
