Millimeter-Wave MIMO radar for contactless neonatal heart-rate assessment: performance under common resuscitation-related maneuvers and feasibility in clinical workflow

1

Millimeter-wave MIMO radar was evaluated for contactless neonatal heart rate monitoring during standard resuscitation procedures.
2

The study involved 60 clinically stable neonates monitored with radar and a 3-lead ECG to assess heart rate measurement performance.
3

Radar-derived heart rate showed good agreement with ECG under quiet conditions, with most measurement errors below 10 bpm.
4

Postural changes significantly increased measurement error, leading to systematic underestimation of heart rate.
5

The findings suggest radar may serve as an adjunct tool for short-window heart rate assessment in neonatal care.
