Development of a wireless oral-feeding monitoring system for preterm infants

Area of Science:

• Neonatal Medicine
• Biomedical Engineering
• Developmental Pediatrics

Background:

• Oral-feeding disorder is prevalent in preterm infants, impacting growth and neurodevelopment.
• Current assessments of feeding coordination are subjective and lack simultaneous monitoring.
• Difficulties in coordinating sucking, swallowing, and breathing pose risks like aspiration and apnea.

Purpose of the Study:

• To develop and validate a wireless system for objective, simultaneous monitoring of sucking, swallowing, and breathing during oral feeding in preterm infants.
• To provide quantitative data for assessing feeding coordination and identifying neurodevelopmental risks.
• To overcome the limitations of subjective and phased clinical evaluations.

Main Methods:

• A wireless monitoring system was designed, incorporating a pressure sensor for sucking, a microphone for swallowing sounds, and surface electromyography for breathing.
• A specific algorithm was developed to detect and evaluate sucking-swallowing-breathing events.
• The system's accuracy and clinical relevance were verified by comparing its parameters with established clinical findings in both term and preterm infants.

Main Results:

• The wireless system successfully and quantitatively monitored sucking pressure, swallowing sounds, and breathing movements.
• The developed algorithm effectively detected sucking-swallowing-breathing activities.
• Clinical verification demonstrated the system's practicality and value in assessing oral feeding in infants.

Conclusions:

• The proposed wireless oral-feeding monitoring system offers an objective and quantitative method for evaluating feeding coordination in preterm infants.
• This technology can aid in early identification of high-risk infants for neurodevelopmental delay.
• The system provides a valuable tool for improving clinical judgment and management of oral feeding disorders in neonates.
