The Problem

Current CPR devices do not confirm blood perfusion to the vital organs.

Guideline-compliant CPR can still fail to produce meaningful blood flow to the brain. Anatomical variability, improper hand placement, and collapse of the left ventricular outflow tract can all render compressions ineffective — even when performed "correctly."

Today's rescuers — lay bystanders are not equipped to acurately determine perfusion and even EMS professionals are compromised until ALS equipment arrives such as Ultrasound/Cardiac-Monitor Defibrillators/NIBP/SpO2 devices. Resuscitation thought leaders formally identified this as a major unmet clinical need in 2023. Takhoma Medical is the answer.

"Current CPR tools measure how compressions are delivered — not whether they are physiologically effective for the individual patient." — Takhoma Medical Clinical Brief, 2026

The Solution

The CPR
Companion

A compact, single-use device that provides real-time physiological feedback during CPR — confirming blood perfusion and coaching rescuers to optimize hand placement for each individual patient. Designed for lay rescuers, EMS, and in-hospital teams. $100 target price. Over two-year battery life.

🩸

Real-Time Perfusion Feedback

Monitors Multiple perfusion indicators continuously, telling rescuers whether blood is actually reaching the vital organs of the body — not just how they're compressing.

🖐️

Optimal Hand Placement

Guides rescuers to the sternum position that produces the best perfusion for that specific patient's anatomy, in real time.

🚦

Simple 3-Light Interface

Designed for use under extreme stress — minimal training required. A universal visual language that works for untrained bystanders and critical care teams alike.

🔬

Separate Pressure/Accelerometer/Force Sensors

Independent Pressure,Accelerometer, and force sensors applied to optimize compression depth, speed of compression and release, and rate.

⚡

Single-Use Ready

One-time-use form factor eliminates concerns over sterilization/cross-contamination and supports rapid deployment across pre-hospital and hospital settings.

🔗

AED-Compatible Platform

Engineered for future integration into existing AEDs and cardiac monitor-defibrillators, Vital Sign Monitors, Central Stations enabling adoption through established clinical channels.

Who It Helps

Built for every rescuer, in every setting.

The CPR Companion is designed to work wherever cardiac arrest happens — from a community center floor to a hospital ICU. Its simple interface requires no special training, while its physiology-driven feedback serves the most advanced resuscitation teams equally well.

🚶

Lay Bystanders

The three-light interface and audio speaker guides untrained rescuers to effective compressions from the first seconds of a cardiac arrest — when every moment matters most.

🚑

EMS & First Responders

Pre-hospital emergency teams gain real-time perfusion data to adapt technique on the scene, improving outcomes before hospital arrival.

🏥

Hospital & ICU Teams

Emergency departments and advanced life support teams can optimize in-hospital CPR with the same patient-specific physiological feedback.

📋

CPR Training Programs

Over 25 million people receive CPR training annually worldwide. The CPR Companion can be integrated into training to teach physiology-first technique from the start.

Development Roadmap

From prototype to
FDA clearance.

Takhoma Medical is pursuing a rigorous, phased development path designed to generate the clinical evidence necessary to earn FDA 510(k) clearance and demonstrate the CPR Companion's life-saving effectiveness in real-world emergency settings.

Phase I — Second-Generation Prototypes

Design and production of 10 refined second-generation devices. Engineering validation, bench testing, and hardware refinement to prepare for human subject evaluation.

Phase II — Clinical Evaluation with EMS

FDA Nonsignificant Risk authorization and IDE approval, followed by clinical evaluation with Kootenai County emergency medical personnel. Initial 10 person study collecting real-world data on cardiac arrest patients.

Phase III — 50-Patient Efficacy Study

A 50-patient human subject study using fully operational CPR Companion units deployed by trained EMS personnel. This study is designed to demonstrate real-world effectiveness and generate the clinical data required for FDA 510(k) clearance.

Phase IV — FDA 510(k) Clearance & Initial Deployment

Submission and clearance under the FDA Class II 510(k) pathway, followed by initial deployment with emergency medical services in the Seattle–Spokane–Coeur d'Alene region.
