CPAP

If a baby is born preterm, organ systems can be quite immature and therefore need medical support. Especially the lungs of preterm infants are often not fully developed and if there is a lack of surfactant, a surface active agent that lowers surface tension and prevents atelectasis (collapsed lung), they are more likely to develop respiratory distress syndrome. As the first breath is essentially in the initiation of the transition from the fetal to the post-natal circulation and physiology, infants need further respiratory support such as positive pressure ventilation and supplemental oxygen. If infants are breathing spontaneously but cannot create pressure to prevent the lung from getting atelectatic, continuous positive airway pressure is applied as it provides the infant with positive end-expiratory pressure (PEEP) and maintains the pressure throughout the breathing cycle. It’s like having a balloon: as long as the pressure inside the balloon is greater than outside, it is stable, but as soon as air and pressure slip out, the balloon is going to collapse. In preterm infants the alveoli would collapse as the surface tension is low therefore, they are provided with CPAP. 😊 
However, there are many more possibilites concerning breathing support in babies... Coming soon!
