PauseProbe — Timed Point-of-Care Ultrasound Workflow for Cardiac Arrest

A tablet app paired with any handheld ultrasound probe that runs during CPR: it cues a single image window inside the rhythm-check pause, walks a structured interpretation (cardiac motion, effusion, ventricular function), and maps findings to the 2025 guideline's new ultrasound recommendations and its causative-versus-secondary arrhythmia distinction — then logs everything to the arrest record.
