OBJECTIVE: Automatic adjusting nasal continuous positive airway pressure titration (APAP) has been introduced as an alternative method of establishing pressures for patients with sleep apnea. The performance and accuracy of APAP in nonattended home environment are controversial. This study assessed APAP polysomnographic outcomes and accuracy in a nonattended home environment.
STUDY DESIGN AND SETTING: We conducted a retrospective consecutive case series of 24 consecutive patients who had nonattended APAP and simultaneous full polysomnography (PSG).
RESULTS: APAP was tolerated and reduced obstructive Apnea-Hypopnea Index (AHI) to <10 events/h in all patients. Mean AHI decreased from 38.4 (21.2) to 5.9 (6.6) events/h. Central apneas worsened in one patient. A therapeutic pressure was determined in 91% of patients. Autoset accurately measured residual AHI compared with PSG (R = 0.77, P < 0.001). APAP overestimated the AHI by 1.4 events/h.
CONCLUSIONS: Nonattended APAP is successful in many patients in determining a therapeutic positive pressure setting. Reported AHI via Autoset is similar to that of PSG.
SIGNIFICANCE: APAP reduces AHI and is tolerated in a nonattended environment.
