Zusammenfassung

Fragestellung

Die derzeitige Standardtherapie zur Behandlung der obstruktiven Schlafapnoe ist die CPAP-Therapie. Um einen Überblick über das Nutzungsverhalten der Patienten zu erhalten, wurden in Deutschland flächendeckend Therapiedaten aus dem CPAP-Gerät S8 (Fa. ResMed, Sydney, Australien) ausgelesen und ausgewertet.

Patienten und Methoden

Folgende Daten wurden retrospektiv von 4281 Patienten (Alter: 58,4±11,2 Jahre; 17,6% w., 82,4% m.) erhoben: Apnoe-Hypopnoe-Index (AHI), mittlerer Maskendruck, Maskendruck 95. Perzentil, mittlere Leckage, Leckage 95. Perzentil, Nutzungsdauer, Nutzungseffizienz (Nutzungstage/Gesamttage). Die Daten der letzten 156,7±25,0 Tage (Spanne: 30–180 Tage) wurden über eine Datenkarte aus dem CPAP-Gerät ausgelesen. Informationen über Maskentyp und Therapiedauer wurden ebenfalls ermittelt.

Ergebnisse

Die Therapiedauer betrug 3,5±3,6 Jahre, die maximale Therapiedauer lag bei 15,8 Jahren. Die Patienten nutzten das CPAP-Gerät an 6,4±1,4 Tagen/Woche. Die Anwendungszeit/Nacht betrug 6h 16 min ±1 h 34min. Die Adhärenz lag bei den Schwellenwerten 3 h/Nacht, 4 h/Nacht und 5 h/Nacht jeweils bei 97,0%, 91,8% und 79,9%. Der AHI lag bei 6,2±4,8/h, der mittlere Maskendruck bei 8,7±2,0 cmH2O und die mittlere Leckage bei 0,13±0,16 l/s. Das S8 wurde in 71,6% der Fälle im CPAP-Modus betrieben und in 28,4% im APAP-Modus.

Fazit

Im untersuchten Patientenkollektiv war die Therapieadhärenz sowohl im CPAP- als auch im APAP-Modus hoch und die Therapieeffektivität in beiden Modi gut.

Abstract

Aim of the study

CPAP (continuous positive airway pressure) is the therapy of choice for obstructive sleep apnea (OSA). In order to obtain an overview on CPAP adherence, therapy data from the CPAP device S8 (ResMed, Sydney, Australia) were obtained and evaluated.

Patients and Methods

The data of 4281patients (age 58.4±11.2 years; 17.6% female, 82.4% male) were retrospectively collected: apnea hypopnea index (AHI), mean mask pressure, mask pressure 95th percentile, mean leakage, leakage 95th percentile, duration of use, efficiency (days of use/total days). Data from the last 156.7±25.0 days (range 30–180 days) were obtained from the data card included in the CPAP device. Information on mask type and therapy duration were also determined.

Results

Therapy duration was 3.5±3.6 years, maximum therapy duration was 15.8 years. The patients used the CPAP device 6.4±1.4 days/week. Use/night was 6 h 16 min±1 h 34 min. Adherence was 97.0%, 91.8%, and 79.9% regarding the thresholds 3 h/night, 4 h/night and 5 h/night. The apnea−hypopnea index (AHI) was 6.2±4.8/h. Mean mask pressure was 8.7±2.0 cmH2O and mean leakage 0.13±0.16 l/s. The S8 was used in 71.6% of the cases in the CPAP mode and in 28.4% in the APAP mode.

Conclusion

Therapy adherence was high in both the APAP and CPAP modes. Furthermore, therapy efficiency was good.
