Redmond-based Physio-Control today rolled out a new technology called TrueCPR which is designed to help first responders and other health professionals more accurately determine whether they are performing CPR chest compressions properly.

truecprThe unit uses a proprietary technology known as Triaxial Field Induction to monitor the depth of compressions, using magnetic fields to pinpoint the exact distance between the chest pad and back pad.

By doing so, CPR providers can get real-time feedback to make sure compressions are being performed in at least two inches of depth on the chest and at the proper rate. Reports also can be generated after the incident.

“Unlike accelerometer-based devices, which have been shown to overestimate chest compression depth on soft surfaces, TrueCPR measures the relative distance from the chest sensor to reference pad, regardless of patient movement, thus it can be used on surfaces such as a hospital gurney, mattress or in a moving ambulance,” the company writes in its marketing materials.

The device, which sells for $1,795, marks the first new product release since Physio-Control was acquired by Bain Capital for $487 million more than a year ago. Physio-Control, which was founded more than 50 years ago, now has more than 650,000 Lifepak defibrillators in operation.
