Referring to all systems that bubble as bubble CPAP is misleading and potentially hazardous!

Referring to all systems that bubble as bubble CPAP is misleading and potentially hazardous!

Sonja Baldursdottir and colleagues in their 2020 article published in the Archives of Diseases of Childhood Fetal and Neonatal edition identified three major alterations in newly introduced bubble CPAP systems that are different from the original bCPAP design:
  1. Resistance of nasal interface,
  2. Volume of dead space and
  3. Diameter of expiratory tubing.
They conducted a study to examine the effect of these alterations on CPAP delivery and work of breathing in a mechanical lung model. They found out that high-resistance interfaces and narrow expiratory tubing increased the work of breathing. Additionally, narrow expiratory tubing resulted in higher CPAP levels than indicated by the submersion depth. They concluded that using high-resistance interfaces and narrow expiratory tubing significantly impacted CPAP delivery and imposed work of breathing. They recommend that new bubble CPAP systems should include low-resistance interfaces and wide-bore tubing and be compared with the original bCPAP. Baldursdottir S, et al.

The Bubble CPAP Institute is an interactive educational platform aiming to make the knowledge and skill set of Bubble CPAP accessible to practitioners who care for neonates and young infants across the globe. This platform will primarily focus on the know-how and will offer educational modules on issues like when to consider bCPAP in managing infants with respiratory distress, how to assemble the bCPAP circuits, how to apply the nasal interface and how to troubleshoot bedside issues.
