Why is CPAP considered useful in preterm infants?

CPAP, or Continuous Positive Airway Pressure, is especially useful in preterm infants primarily because it helps to prevent breathing difficulties that are commonly associated with their underdeveloped lungs. Preterm infants often experience respiratory distress syndrome (RDS) due to a lack of surfactant, which is crucial for keeping the alveoli open and facilitating effective gas exchange. By applying a continuous positive pressure, CPAP keeps the alveoli open during both inhalation and exhalation, which improves oxygenation and reduces the work of breathing.

This non-invasive form of respiratory support helps maintain lung volume, stabilizes oxygen saturation levels, and minimizes the risk of airway collapse. As a result, CPAP can often prevent the need for more invasive interventions, such as intubation, which can pose additional risks to these vulnerable infants. The other options do not accurately reflect the primary purpose and benefit of CPAP in this context.
