Development of Neonatal Flow Sensor for Neonatal Resuscitation

Area of Science:

• Biomedical Engineering
• Neonatal Care
• Medical Device Development

Background:

• Neonatal mortality remains a significant global health challenge, with millions of deaths in the first month of life.
• Preterm birth and intrapartum complications like birth asphyxia are leading causes of neonatal death.
• Effective positive pressure ventilation is critical for newborns, but challenging due to their small, stiff lungs.

Purpose of the Study:

• To develop and evaluate a novel flow sensor designed for neonatal resuscitation.
• To assess the sensor's performance in delivering accurate ventilation parameters to newborns.
• To improve the efficacy and safety of respiratory support for critically ill neonates.

Main Methods:

• Development of a custom-designed flow sensor for neonatal ventilation.
• Testing of the sensor's flow resistance, measurement accuracy, and robustness.
• Evaluation of the sensor's impact on dead space when connected to an intubation tube.

Main Results:

• The developed flow sensor exhibited low flow resistance (0.18kPa@10L/min).
• It demonstrated superior measurement accuracy at low flow rates compared to existing commercial sensors.
• The sensor proved robust to noise and did not increase dead space during simulated use.

Conclusions:

• The novel flow sensor is a promising tool for enhancing neonatal resuscitation.
• Its accuracy and low resistance can aid healthcare providers in delivering optimal ventilation.
• Future work will focus on display integration and usability for clinical application.
