Study Notes
Benefits of Bubble CPAP
- Improves gaseous exchange and decreases the work of breathing by increasing and maintaining functional residual capacity (FRC), which in turn improves gas exchange and lowers PaCO2.
- Produces a high-frequency oscillatory ventilator-like effect, which augments the ventilatory effect.
- Improves breathing patterns and reduces resistive work of breathing in former preterm infants with mild respiratory distress.
Effects on Lung Development
- Increases total lung capacity by 40% and lung weight, as well as total protein and DNA content, after continuous bCPAP treatment for 2 weeks.
Decreased Bronchopulmonary Dysplasia (BPD)
- Early initiation of bCPAP in very low birth weight infants reduces the incidence of BPD.
- Early bCPAP in the delivery room has been shown to be feasible and successful in 76% of infants with RDS weighing 1250g or less, resulting in reduced incidence of BPD.
- The early initiation of bCPAP through nasal prongs has been suggested as the reason for the noted effect.
Contraindications of bCPAP
- Unrepaired congenital diaphragmatic hernia
- Esophageal atresia
- Tracheoesophageal fistula
- Choanal atresia
- Cleft palate
- Severe cardiovascular instability
- Severe ventilatory impairment
