The Vision

Advanced CPR Solutions® (ACS) approached Evergreen Research, Inc. (ERI) with a concept prototype for a CPR patient positioning system and asked that it be engineered into a commercial product suitable for use in emergency medical situations. The concept prototype was based on research which showed that a 20-25 cm elevation of a patient’s head and 9-10 cm elevation of the thorax, when delivering high quality CPR during sudden cardiac arrest cases, had the potential to increase the survival rate by a factor of four.

Evergreen Research used a structured approach to create and implement the project design.

Human Factors Design Approach

Human Factors Design Approach

The Result.

The EleGARD™ Patient Positioning System was designed using a human factors design approach, to assure that wide variations in human anatomy were taken into account. The design process included mechanical, electrical and software design. Working with ACS, Evergreen Research studied CPR protocols and performed testing and analysis to create a product that would seamlessly fit into CPR using a “bundle of care” and fulfill the ACS vision for its initial generation of product.

Evergreen Research now manufactures the EleGARD Patient Positioning System for ACS. Shipments began in March of 2019, and volumes are increasing as market acceptance grows.


Engineering Services 

  • Mechanical Design

  • Electrical Design

  • Software Design

Protocol Study

  • The requirement for high quality CPR from manual and automated chest compressions led ACS and Evergreen Research to incorporate a LUCAS® backplate into the EleGARD System.

Regulatory Strategy 

  • Coordinated with ACS to confirm EleGARD as a patient positioner, and therefore, a Class 1 medical device.

  • Crafted a Quality Management System compatible with USA and international regulations.

Testing and Analysis

  • Finite element analysis was performed to estimate robustness of plastic molded parts.

  • Reliability testing was performed to confirm the design’s ability to withstand force and shock.

  • Successfully passed nationally recognized test laboratory (NRTL) safety testing.

  • Successfully passed international safe transit association (ISTA) shipping tests.


  • Evergreen Research now manufactures the EleGARD System for ACS.

  • Volume of shipments continue to increase as market acceptance grows.
