Premature infants often cannot successfully and coordinately complete their oral feeding. Mature sucking, swallowing, and respiration activities are crucial indicators for the survival of newborn infants. Due to the vulnerability and unobvious muscle activities of premature infants, current clinical care givers mainly depend on the subjective behavioral observation of infants during oral feeding. There is still lack of an integrated oral feeding monitoring system to objectively and quantifiably monitor the related physiological parameters of premature infants. In this study, a wireless multi-parameter monitoring system for oral feeding of premature infants was proposed to monitor the sucking-swallowing-respiratory activities and the heart rate variability to provide quantitative indices of oral feeding. Here, a novel sucking pressure sensing module was also developed to monitor the premature infant\'s sucking pressure under oral feeding to avoid the immersion influence of milk. The experimental results showed that the proposed system detected the related physiological parameters of premature infants during oral feeding effectively and may provide an objective clinical evaluation tool for oral feeding ability and safety of premature infants in the future.

Oral-feeding disorder is common in preterm infants. It not only shows the adverse effect for growth and neurodevelopment in clinical but also becomes one of the important indicators of high-risk group for neurodevelopment delay in preterm infants. Preterm infants must coordinate the motor patterns of sucking, swallowing, and respiration skillfully to avoid choking, aspiration, oxygen desaturation, bradycardia, or apnea episodes. However, up to now, the judgment and classification severity in preterm infants are mostly subjective and phasic evaluations. Directly monitoring the coordination of sucking-swallowing-breathing during oral feeding simultaneously is difficult for preterm infants. In this study, we proposed a wireless oral-feeding monitoring system for preterm infants to quantitatively monitor the sucking pressure via a designed sucking pressure sensing device, swallowing activity via a microphone to detect swallowing sound, and diaphragmatic breathing movement via surface electromyogram. Moreover, a sucking-swallowing-breathing detection algorithm is also proposed to evaluate the events of sucking-swallowing-breathing activities. Furthermore, verification of the accuracy and rationality of oral-feeding parameters with clinical findings including sucking, swallowing, and breathing in term and preterm infants had proved the practicality and value of the proposed system.

Nutritive sucking is the approach of obtaining primary food for newborns within six months. However, completing the precise coordination of sucking-swallowing-respiratory actions under oral feeding is usually difficult for preterm infants and may affect the body and neural development of the premature infant. For this reason, how to obtain the quantitatively physiological information related to oral feeding is useful for physicians making more accurate clinical diagnoses for oral feeding disorders. However, there is still lack of monitoring systems for evaluating the feeding skill of infants quantitatively and objectively. The assessment of the feeding skill or the diagnosis of oral-feeding disorders still depends on the clinical experience of medical staffs. In this study, a novel wireless monitoring system is proposed to evaluate the feeding behavior of infants quantitatively and objectively and analyze the characteristics of these actions under oral feeding. Here, a specific feeding bottle and an optical probe are also designed and successfully applied to noninvasively monitor the sucking and respiratory actions, and a microphone is also applied to monitor the swallowing action. From the experimental results, the sucking and swallowing rate increases and the respiratory rate decreases with the increase of the infant age. Moreover, the duration increases and the interval of sucking-action sequence decreases with the increase of the infant age respectively. The proposed system successfully assesses the feeding behavior of preterm infants and may provide an objective evaluation tool for oral feeding ability and identifying the risk of infant developmental delay in the future.
