Project Goal/Summary: The goal of this project is to develop an improved Cardiopulmonary resuscitation (CPR) training system that will enhance and optimize trainee learning as to the key components of CPR compression needed for CPR success and the saving of lives. The envisioned system will improve training as to correct hand position, depth, force and timing of chest compression, while simultaneously providing digital feedback of all parameters as well as visual evidence of resultant blood flow. The system will log trainee performance, changes/improvements between training sessions, generate a report, allow for inter-trainee assessment and comparison – all means of providing feedback for reinforcement and improved learning. Providing individuals with an enhanced CPR training system, affording instant feedback of the essential elements of CPR maneuvers, movements and procedural elements will ultimately improve resuscitative efforts and go a long way to save lives. Hence, doing CPR right is Life.
Project Background: Cardio-pulmonary arrest (CPA) is a life threatening, not uncommon event which is associated with significant morbidity and mortality. Cardiopulmonary resuscitation has been shown to be lifesaving for CPA. In the U.S. more than 400,000 out-of-hospital CPA events occur annually, with only 40% of victims receiving CPR, often times poorly performed. While initially advanced as a combination of compression and breathing, current CPR has been streamlined to be one of “compression only,” notably through seminal work performed at the University of Arizona. Current American Red Cross and AHA guidelines outline how to perform CPR and provide training courses for certification. Despite this, CPR training is often limited and with inadequate feedback to the trainee. The most common tool utilized to train individuals is that of a CPR mannequin or dummy. These devices while attempting to appear lifelike do not provide the feedback, in a quantitative fashion, as to the appropriate location of hands/position; the frequency, force and depth of compression, all necessary for effective blood circulation in the compromised arrested patient. Further, visual means of instantly evidencing performance and accuracy thresholds, as well as visually recognizable blood (fluid) flow are lacking. The current project aims to overcome these limitations and advance a new system to enhance overall training.
Requirements: Step1: Get up to speed - Team will research current CPR methods, training requirements, mannequins/dummies and other facsimile tools currently used and outline gaps/limitations. Team will have the benefit of work done this past summer by a range of medical students under ACABI on this project. Step 2: Design and build chest force displacement unit w contained sensors – a modular pusher plate/spring system with appropriate/tunable resistance (to mimic a range of chest stiffness) will be fashioned with equipped force sensors (strain gauge, load cell, piezoelectric or equivalent) capable of instant digital readout. System will be designed to function as standalone or placed in the chest cavity of a rubberized mannequin. Step 3 – Design and build a hand/finger placement touchpad system – designed with sensors indicating correct finger placement and contact for a range of chest configurations – male and female. Step 4 – Design and build blood (fluid) flow system – a visual transparent tubular facsimile of the carotids, incorporable into a mannequin, will be fabricated with contained mock blood to visually depict blood flow coordinate with correct compression. System may be electrically pumped synched as to flow rate with force/depth of compression to avoid need for direct mechanical coupling to force/compression unit. Step 5 - Data collection, Heads-up display and Report generation – A readout display means with actual vs optimal performance threshold indicators will be fashioned (consider LabView), system will allow serial as well as inter-trainee comparison and report generation.
