Gegenüber CPAP haben die Patienten unter Velumount:

  • weniger Nebenwirkungen
  • bessere systolische Blutdruckwerte
  • eine bessere Therapietreue
  • und insbesondere eine bessere Therapiezufriedenheit

Data  of  18  patients  with  obstructive  sleep  apnea  syndrome  (OSAS)  on  therapy  with  continuous positive airway pressure (CPAP) (with good efficacy) and with the Velumount® device were collected by respiratory polygraphy, blood pressure measurement, questionnaires, and neuropsychological tests to  compare  for  the  first  time  the  effects  of  the  Velumount®  device  to  the  one  of  CPAP  therapy.
Number  of  side  effects  (p < 0.001),  oxygen  saturation  (p < 0.01),  and  systolic  blood  pressure (p < 0.05) significantly decreased with the Velumount® device. Compliance, therapy satisfaction, and apnea-hypopnea index significantly (AHI; p < 0.01) increased with the Velumount® device. There was no  significant  difference  in  the  proposed  compliance  adjusted  AHI.  Average  improvements  in neuropsychological  performance  lay  within  the  range  of  the  repetition  effect.  Alternatives  to  CPAP therapy  (such  as  the  Velumount®  device)  should  be  individually  adapted  to  OSAS  patients.  The proposed comparative study factors should be considered in required follow-up comparative studies.
