Study Notes
bCPAP Effects on Mean Airway Pressure
- bCPAP increases mean airway pressures.
bCPAP Effects on Lung Inhomogeneity
- bCPAP decreases lung inhomogeneity, promoting more uniform ventilation.
bCPAP Effects on Neutrophil Migration and Hydrogen Peroxide Production
- bCPAP reduces neutrophil migration and hydrogen peroxide production in preterm lambs, potentially mitigating inflammation.
bCPAP Effects on Total Lung Capacity
- bCPAP increases total lung capacity in animal studies.
bCPAP Effects on Bronchopulmonary Dysplasia (BPD)
- Early initiation of bCPAP lowers the incidence of BPD in very low birth weight infants.
bCPAP Complications
- Excessive CPAP can lead to pneumothorax, a potentially serious condition.
Preventing Nasal Injury from Nasal Prongs
- Rotation of nasal prongs every 24 hours helps prevent nasal injury.
Contraindications for bCPAP
- Choanal atresia, a congenital condition where the back of the nasal passages are blocked, is a contraindication for bCPAP.
Consequences of Nasal Obstruction
- Nasal obstruction during NCPAP can result in ineffective ventilation.
Gastric Distension Complications
- Gastric distension during CPAP can lead to vomiting and aspiration, which can be life-threatening.
