GER clinical presentation may vary within a wide range of symptoms, being vomiting, regurgitations and cardiorespiratory events, such as apnoeas or bradycardia, the most common in the preterm population. Particularly, apneic episodes are inversely related to the gestational age (GA) and might be associated with such pathological events as hypoxia, hypercapnia or pressure variability, which seem to negatively affect the long-term neurological development of preterm babies.
