Brief Summary

Context: The obstructive sleep apnea syndrome (OSAS), i.e., snoring with difficulty breathing during sleep, is common in children. Continuous positive airway pressure (CPAP) therapy is the usual treatment for children who do not improve following surgery. However, CPAP is uncomfortable and is often not tolerated. We therefore plan to study a modification of bilevel positive airway pressure therapy, BiPAP with Bi-Flex that may be more comfortable. Objectives: The primary objective of this study is to determine whether BiPAP with Bi-Flex results in improvement in adherence as compared to CPAP. The secondary objective is to determine whether Bi-Flex has similar therapeutic efficacy compared to CPAP, as determined by sleep study. Additional objectives include comparing CPAP and Bi-Flex effects on comfort and determining which parameters predict adherence. Study Design/Setting/Participants: A single center, randomized controlled double-blind study of Bi-Flex vs CPAP use in children with OSAS over a 3 month period. Intervention: Bi-Flex vs CPAP Study Measures: Objective compliance recordings, sleep study results, subjective questionnaire results. .

Study Arms (2)

Bi-Flex

ACTIVE COMPARATOR

Subjects randomized to this arm will undergo a clinical Bi-Flex sleep study. Following a baseline polysomnography, subjects in this arm will undergo bilevel positive airway pressure with pressure release technology (Bi-Flex) therapy. In this randomized, double-blinded clinical trial, patients with obstructive sleep apnea will be randomized to Bi-Flex or CPAP, and repeat polysomnography will be performed on pressure at 3 months. Objective adherence data will be obtained at 1 and 3 months.

Device: Bi-Flex

CPAP

ACTIVE COMPARATOR

Subjects randomized to this arm will undergo a clinical CPAP titration sleep study. Subjects in this arm received standard continuous positive airway pressure (CPAP) therapy. In this randomized, double-blinded clinical trial, patients with obstructive sleep apnea will randomized to CPAP or Bi-Flex, and repeat polysomnography will be performed on pressure at 3 months. Objective adherence data will be obtained at 1 and 3 months.

Device: CPAP

Interventions

Eligibility Criteria

Age2 Years - 16 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Males or females aged 2 to 16 years.
  • OSAS diagnosed on polysomnography.
  • Positive airway pressure therapy indicated by patient's physician because surgery was either contraindicated or ineffective.
  • No plans for upper airway surgery in the next 3 months.

You may not qualify if:

  • Age less than 2 years, as infants and toddlers have different pulmonary mechanics from older children, and may require intense behavioral modification programs prior to CPAP use.
  • Age greater or equal to 16 years, as results may be similar to adult studies in these older patients.
  • Previous use of CPAP / bilevel ventilation.
  • Unable to read / understand English. -
