    Area of Science:

    • Medical Devices
    • Respiratory Physiology
    • Pediatric Critical Care

    Background:

    • Accurate measurement of respiratory flow is crucial for managing infants and neonates.
    • Existing devices may add significant dead space or work of breathing.
    • Need for a practical and precise tool for neonatal respiratory monitoring.

    Purpose of the Study:

    • To describe a new flat-bodied pneumotachograph head for infant and neonatal respiratory flow measurement.
    • To ensure easy and accurate integration with standard clinical equipment.
    • To minimize the added work of breathing during respiratory monitoring.

    Main Methods:

    • Design and interposition of a flat-bodied pneumotachograph head between endotracheal tube connectors.
    • Incorporation of heating and humidification for inspired gases.
    • Focus on accurate inspiratory and expiratory flow recording.

    Main Results:

    • The new pneumotachograph head allows for easy and accurate measurement of respiratory flow in infants and neonates.
    • The device does not appreciably increase the work of breathing.
    • Methods for heating the head and conditioning inspired gases are detailed.

    Conclusions:

    • The described pneumotachograph head offers a practical solution for accurate neonatal respiratory flow monitoring.
    • It facilitates precise measurement within clinical settings.
    • The design addresses the need for minimal impact on patient respiratory mechanics.
