Bilevel positive airway pressure (BPAP) devices offer advanced noninvasive ventilation (NIV) for complex sleep disorders beyond obstructive sleep apnea (OSA). This review covers BPAP therapies for hypoventilation, treatment-emergent central sleep apnea, and central sleep apnea syndromes.
Area of Science:
- Pulmonary Medicine
- Sleep Medicine
- Biomedical Engineering
Background:
- Continuous positive airway pressure (CPAP) revolutionized obstructive sleep apnea (OSA) treatment.
- Bilevel positive airway pressure (BPAP) devices evolved to manage complex sleep-related breathing disorders resistant to CPAP.
- Advanced noninvasive ventilation (NIV) modes emerged from BPAP platforms to address intricate cardiorespiratory conditions.
Purpose of the Study:
- To review key aspects of various bilevel positive airway pressure (BPAP) therapies.
- To discuss the application of these therapies in treating sleep-related hypoventilation disorders.
- To explore their use in managing treatment-emergent central sleep apnea and central sleep apnea syndromes.
Main Methods:
- Literature review of bilevel positive airway pressure (BPAP) therapies.
- Analysis of advanced noninvasive ventilation (NIV) modes.
- Summary of clinical applications for specific sleep-related breathing disorders.
Main Results:
- Bilevel PAP therapies include BPAP with/without backup rate, adaptive servoventilation, and volume-assured pressure support.
- These advanced NIV modes are crucial for managing complex cardiorespiratory pathophysiology.
- The review highlights the efficacy of these devices for specific hypoventilation and central sleep apnea conditions.
Conclusions:
- Bilevel PAP therapies represent significant advancements in noninvasive ventilation for complex sleep disorders.
- Understanding these advanced modes is essential for treating a range of sleep-related breathing conditions.
- Further research and clinical application of these technologies can improve patient outcomes.
