Objective:

To evaluate the performance and workflow feasibility of a millimeter-wave MIMO radar system for contactless neonatal heart rate assessment during routine resuscitation-related maneuvers.

Approach:

Key Findings:

• Radar-derived HR showed agreement with ECG under quiet conditions, with RMSE values mostly below 10 bpm.
• Measurement performance was preserved during drying, suctioning, and auscultation, but postural change significantly increased error and caused systematic HR underestimation.
• In the real-workflow experiment, mean radar-derived HR differences from auscultated HR were centered near 0 bpm, with most per-second errors ≤5 bpm.

Interpretation:

Remove unsupported conclusions and rephrase to reflect only the findings.

Limitations:

• Postural change was identified as a significant source of increased measurement error.
• Continuous beat-to-beat accuracy was not validated and requires further investigation.

Conclusion:

Revise to eliminate unsupported claims about the potential role of radar.
