1. Bubble CPAP in neonatal care: mechanisms, evidence, and pathways to optimization.
This review integrates the physiological underpinnings and clinical evidence for bubble CPAP in neonates, emphasizing the role of low-amplitude, high-frequency pressure oscillations that interact with lung mechanics. It proposes practical directions to optimize device design and clinical implementation.
Impact: Bubble CPAP is a cornerstone of non-invasive neonatal respiratory support; clarifying its mechanisms and evidence base can improve standardization and guide optimization across settings.
Clinical Implications: Adopting standardized protocols for interface selection, pressure levels, humidification, leak management, and monitoring may reduce invasive ventilation needs and complications in preterm infants. Mechanistic insights into oscillations can inform individualized settings and device design.
Key Findings
- Bubble CPAP produces continuous distending pressure via a submerged expiratory limb, generating low-amplitude, high-frequency pressure oscillations.
- These oscillations are transmitted to the infant and vary dynamically with airway and lung mechanics, potentially contributing to physiological benefits.
- The review synthesizes historical context, physiological rationale, clinical evidence, and delineates priorities for optimization of bubble CPAP.
Methodological Strengths
- Integrates mechanistic physiology with clinical evidence across historical and contemporary sources.
- Provides a clear conceptual framework linking oscillatory pressure dynamics to potential clinical benefits.
Limitations
- Narrative review without primary data or systematic methodology may introduce selection and publication biases.
- Heterogeneity in devices, circuits, and clinical protocols limits direct comparability and definitive practice recommendations.
Future Directions: Quantify oscillatory components and their interaction with airway/lung mechanics; perform comparative evaluations across devices/circuits; conduct prospective trials to identify optimal settings; advance bench-to-bedside translational studies.
Bubble continuous positive airway pressure (CPAP) is a widely used non-invasive respiratory support strategy for neonates and is commonly employed in the management of preterm infants with respiratory distress. Bubble CPAP generates continuous distending pressure by submerging the distal expiratory limb in water, producing low-amplitude, high-frequency pressure oscillations as airflow escapes and bubbles into the water canister. These oscillations, which are transmitted back to the neonate, vary dynamically with airway and lung mechanics and may contribute to the physiological benefits observed with bubble CPAP. This review summarizes the historical context, physiological rationale, clinical evidence supporting bubble CPAP, and areas for future optimization.
