    Summary
    This summary is machine-generated.

    Heart rate variability (HRV) data can estimate functional maturational age (FMA) in infants using machine learning. This non-invasive method may help monitor infant development in neonatal intensive care units.

    Area of Science:

    • Neonatal physiology
    • Biomedical engineering
    • Machine learning in healthcare

    Background:

    • Assessing infant maturational status is crucial for neonatal care.
    • Current methods may be invasive or time-consuming.
    • Functional maturational age (FMA) deviation from postmenstrual age (PMA) indicates developmental progress.

    Purpose of the Study:

    • To evaluate the efficacy of heart rate variability (HRV) data for estimating infant FMA.
    • To develop a machine learning model for non-invasive FMA assessment.
    • To explore HRV, respiration rate variability (RRV), and bradycardia as potential biomarkers for maturation.

    Main Methods:

    • Acquired HRV data from 50 healthy infants (25-41 weeks gestational age).
    • Utilized an ensemble machine learning (EML) model with feature selection (filtering, genetic algorithms).
    • Validated the model using HRV, RRV, and bradycardia data.

    Main Results:

    • The EML model estimated FMA from HRV data with a mean absolute error of 0.93 weeks.
    • Similar accuracy was achieved using RRV and bradycardia data.
    • The model demonstrated the potential for real-time, non-invasive monitoring.

    Conclusions:

    • HRV, RRV, and bradycardia data can accurately estimate infant FMA.
    • This approach offers a non-invasive, real-time method for monitoring neonatal development.
    • The FMA deviation from PMA can serve as a valuable clinical indicator in neonatal intensive care units.
