“…Results on the feasibility of treatment with some auto-nCPAP devices have been published as preliminary studies and/or abstracts [5-7, 20, 21]. Some devices have been designed to detect respiratory events, flow limitation and snoring [5,20], whereas others have been designed to detect only respiratory events [21], or both respiratory events and snoring [6,7].…”

E Ev va al lu ua at ti io on n o of f a an n a au ut to o--n nC CP PA AP P d de ev vi ic ce e b ba as se ed d o onWe observed that a single night of auto-nCPAP improved the apnoea/hypnoea index (AHI) (12±21 vs 51±31 disordered breathing events·h -1 of sleep (mean±SD)), the awakening-arousal index (13±20 vs 40±26 arousals·h -1 of sleep), and duration of slow wave sleep (102±49 vs 71±56 min) but not of rapid eye movement (REM) sleep (55±31 vs 64±38 min). Auto-nCPAP was effective (apnoea/hypopnoea and arousal indices <10 events·h -1 ) in all but three patients. Auto-nCPAP was ineffective in one patient, whose obstructive respiratory events were not preceded by nasal mask pressure vibration detection, and in two patients who were quasi-permanent mouth breathers.Snoring detection may be effective in sleep apnoea syndrome with heavy snoring and without permanent mouth breathing, during the first night of nasal continuous positive airway pressure treatment.

“…An alternative is to automate the titration process and determine a single pressure suitable for subsequent at-home fixed pressure treatment. The validity of such a strategy in correcting sleep breathing disorders has been demonstrated when compared with manual titration [8,9]. However, whether this permits a substantial reduction in or abolition of laboratory-based tests needed to titrate CPAP in OSA patients remains unknown.…”

“…Variability in hypopnoea detection has already been mentioned and is probably critical during an "on-line" procedure such as manual titration. Arousal detection is an even more complex issue as both the criteria used [13] and the normal values [14] inspiratory flow limitation may be recognized from flow contour but this is undoubtedly more easily and accurately done automatically by a specific algorithm than by visual inspection [8,12]. On the other hand, the titration should not be performed only by increasing the pressure.…”

“…Most patients in the studies had already had a formal sleep study and some had a conventional CPAP titration or were being treated with CPAP before they were first treated with APAP. The results in such patients may differ from those of naïve, untreated patients (11). The performance of APAP under routine conditions, in home use and in a general population of patients with moderate-to-severe OSA is still unclear.…”

BACKGROUND: Autotitrating continuous positive airway pressure (APAP) devices have the potential to address some of the disadvantages of titration and treatment with conventional continuous positive airway pressure (CPAP). Information on the performance of APAP in clinical use is still comparatively limited.OBJECTIVE: To assess the status of APAP devices in the management of obstructive sleep apnea (OSA) by reviewing evidence of their efficacy, effectiveness and costs.METHODS: A systematic search of electronic databases and a review of selected comparative studies on the use of APAP in the diagnosis, titration and treatment of OSA was undertaken. Cost analysis using data applicable to the management of OSA in Edmonton, Alberta was performed.RESULTS: Thirty-three studies met the selection criteria: three on the use of APAP in diagnosing OSA; six on APAP for titration; 14 that considered short-term treatment outcomes; and 10 that addressed longer-term treatment of OSA. In most studies, patients suffering from cardiac, pulmonary and other medical conditions were excluded. Available data suggested some potential for the use of APAP in the diagnosis of OSA, but further validation is needed. In titration, estimated treatment pressures tended to be lower with APAP than with the manual titration of CPAP. Although lower treatment pressures were achieved with APAP, there was no significant difference in clinical outcome measures between APAP and CPAP. Estimates of costs suggested that APAP may provide savings in some scenarios.CONCLUSIONS: APAP shows promise in the management of OSA; however, given the exclusion of some categories of patients from trials of this technology, caution is still required in its use.
