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.

Concept

A tablet app that pairs with any handheld ultrasound probe and runs alongside the resuscitation. At each rhythm-check pause it cues the operator to a single subxiphoid or parasternal window, keeps the image attempt inside the pause, and then walks a short structured interpretation — cardiac motion present or absent, pericardial effusion, gross ventricular function — mapping each finding to the 2025 guideline's recommendations on point-of-care ultrasound in the advanced life support setting and to its causative-versus-secondary arrhythmia distinction (an effusion with pulseless electrical activity points toward a causative pathology and a targeted intervention; absent motion with a secondary rhythm points toward continuing the standard algorithm). Every finding is timestamped and attached to the arrest record, replacing undocumented, pause-lengthening ad-hoc scanning with a protocol-conformant, logged decision input.

Why now

The 2025 AHA Adult Advanced Life Support guidelines bring point-of-care ultrasound into the advanced life support setting and separately underscore identifying causative versus secondary arrhythmias to inform the appropriate timing of therapeutic strategies — two additions that combine into one concrete product need: when to scan, what to look for, and what each finding changes. Handheld probes (Butterfly iQ, Philips Lumify, GE Vscan) are already widely deployed in emergency departments, so the hardware layer exists; what is missing is the arrest-specific timing and interpretation workflow that the new guideline now calls for. The product is sized to demonstrated readiness: it operationalizes a formal recommendation and produces structured documentation, without claiming survival benefit.

Backed by 1 paper92

A highly focused clinical workflow tool that operationalizes new 2025 AHA guidelines to standardize POCUS during cardiac arrest without introducing hardware risk.

Evidence strength
5/5
The idea directly maps to the specific 2025 AHA guideline updates regarding POCUS and the causative-versus-secondary arrhythmia distinction.
Market pull
4/5
Emergency departments and EMS systems have high urgency for guideline compliance and structured documentation, though adoption depends on hospital system procurement.
Novelty & moat
4/5
While other apps provide cognitive aids, this specifically bridges the gap between handheld ultrasound hardware and the timing/interpretation requirements of the new arrest guidelines.
Feasibility
5/5
The product is a software layer utilizing existing hardware (Butterfly, GE, Philips), requiring no new medical device certification for the imaging itself.
Wedge clarity
5/5
The wedge is extremely sharp: a single-window image capture during the rhythm-check pause of a cardiac arrest.
Simplicity / focus
5/5
It avoids 'platform' creep by focusing on one specific clinical event and one specific diagnostic goal.

Who benefits

  • Butterfly Networkcompany

    Its handheld Butterfly iQ probe is already in many EDs; an arrest-specific timing and interpretation app differentiates the probe in the highest-acuity use case the new guideline now covers.

  • Philipscompany

    Its Lumify handheld ultrasound has a large ED installed base; a guideline-mapped resuscitation workflow extends Lumify into the newly recommended advanced life support setting.

  • GE HealthCarecompany

    Its Vscan family of handheld probes would gain a software layer that turns the new POCUS-in-ALS recommendation into a repeatable, documented ED procedure.

  • American College of Emergency Physiciansorganization

    Represents the physicians who will have to decide how ultrasound fits into arrest care under the 2025 guideline; a structured, pause-bounded workflow gives them a teachable and defensible standard.

  • National Association of EMS Physiciansorganization

    Its medical-director members write prehospital protocols; a tool that bounds scan time and standardizes interpretation helps them safely extend the new POCUS recommendation into the field.
