Clinical Report: Evaluation of Millimeter-Wave MIMO Radar for Non-Contact Neonatal Heart Rate Monitoring

Overview

This study evaluates the effectiveness of millimeter-wave MIMO radar for non-contact neonatal heart rate monitoring during standard resuscitation procedures. The findings indicate that while the radar system performs well under quiet conditions, measurement error increases with postural changes.

Background

Accurate heart rate assessment is crucial during neonatal resuscitation, as it informs clinical decisions and interventions. Traditional methods like ECG and pulse oximetry have limitations, particularly in the immediate postnatal period. Contactless monitoring using millimeter-wave radar may provide a valuable alternative, minimizing the need for skin contact and allowing for continuous monitoring.

Data Highlights

ConditionRMSE (bpm)
Quiet BaselineBelow 10 bpm
DryingPreserved
Oronasal SuctioningPreserved
AuscultationPreserved
Postural ChangeIncreased Error

Key Findings

  • Radar-derived heart rate showed agreement with ECG under quiet conditions.
  • Most RMSE values were below the 10-bpm benchmark during baseline and simulated maneuvers.
  • Postural changes led to significant underestimation of heart rate.
  • In real-workflow settings, radar-derived heart rates were closely aligned with auscultated heart rates.
  • Errors of ≤5 bpm were the most frequent during auscultation windows.

Clinical Implications

Clinicians should be cautious of increased measurement errors during postural changes.

Conclusion

Millimeter-wave MIMO radar demonstrates potential for contactless heart rate monitoring in neonates.
