Peripheral Chemoreceptor Activity in Preterm Infants: Insights into Respiratory Function and Future Directions

The study aimed to evaluate the changes in peripheral chemoreceptor activity in preterm infants between 32 and 52 weeks postmenstrual age using both quantitative and qualitative measures. The study found that the peripheral chemoreceptor contribution to ventilatory drive was greater at earlier postmenstrual ages and decreased with increasing age. Apnea was a frequent response to hyperoxic testing at earlier postmenstrual ages, suggesting high peripheral chemoreceptor activity. This information may help explain how ventilatory control instability contributes to apnea and sleep-disordered breathing later in childhood.
