A split-night protocol effectively determines continuous positive airway pressure (CPAP) titration for sleep-disordered breathing. This method significantly reduces arousal and apnea-hypopnea index, proving as effective as a full-night CPAP titration.

Area of Science:

  • Pulmonology
  • Sleep Medicine
  • Medical Devices

Background:

  • Sleep-disordered breathing (SDB) affects millions globally.
  • Continuous positive airway pressure (CPAP) is a primary treatment for SDB.
  • Optimizing CPAP titration is crucial for treatment efficacy.

Purpose of the Study:

  • To evaluate the effectiveness of a split-night protocol for CPAP titration in SDB patients.
  • To compare the efficacy of split-night (SN) versus full-night (2N) CPAP titration.
  • To determine if SN titration can accurately establish effective CPAP pressure.

Main Methods:

  • 107 SDB patients underwent two consecutive nights of polysomnography.
  • Night 1: Split-night protocol (baseline followed by CPAP).

  • Night 2: Full-night CPAP titration for confirmation.

    • Main Results:

    • Both SN and 2N showed significant reductions in arousal index, apnea-hypopnea index (AHI), and oxygen desaturation.
    • No significant differences were observed between SN and 2N for key sleep metrics.
    • Final CPAP pressure was comparable between SN and 2N, especially for patients with AHI > 20.

    Conclusions:

    • A split-night protocol is sufficient for effective CPAP titration in SDB patients.
    • This method provides comparable results to a full-night titration.
    • SN titration may be particularly suitable for patients with an AHI greater than 20.
