Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.
Intended capability
Evaluate the sensing evidence for “Agonal-breathing and respiratory-arrest early warning” in a consented, ground-truthed study. This is not a medical device, clinical monitor, diagnosis, or emergency alert.
This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording
A related Healthcare scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Normal periodic thoracic Doppler at 0.1-0.5Hz either flatlines (apnea = loss of the narrowband tone) or degrades to irregular high-amplitude gasps (agonal = sparse, aperiodic bursts), a sharp departure from the baseline respiratory spectrum.
02 Shared processing path
Micro-Doppler respiratory band tracking -> PCA+MVE anomaly manifold flags loss/irregularity of the periodic component -> LD2410 static-target energy over the bed as an independent breathing-presence channel (apnea = static-energy collapse with no exit event) -> CUSUM on respiratory-rate to confirm sustained deviation vs. transient breath-hold
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
03 Validation plan
OPERAnet respiration ground truth to prove apnea/rate-drop detection sensitivity; own-hardware trial with volunteers performing breath-holds and simulated bradypnea vs. capnograph, with a co-located LD2410 confirming static-target energy collapses on every held breath and holds through every breathing interval.
04 Commercial hypothesis
'Opioid-safety respiratory sentinel' — for patient-safety/anesthesia leads meeting post-op sedation monitoring mandates with nothing on the patient; plus tier: one bedside mmWave radar per monitored bed carries the breathing-presence confirm.
