Analog Devices' tech powers Zoll's PocketCPR
Medical device company Zoll Medical has selected Analog Devices' iMEMS technology to enable PocketCPR, Zoll’s palm-sized CPR device, to measure the rate and depth of chest compressions administered by rescuers.

The PocketCPR device uses the digital iMEMS accelerometer to convert the motion of PocketCPR into real-time measurement data to read the rate and depth of CPR chest compressions, the Norwood, Mass.-based Analog Devices stated.

Chelmsford, Mass.-based Zoll’s PocketCPR coaches a rescuer with audio and visual instructions to initiate the rescue steps needed for reviving someone experiencing sudden cardiac arrest, according to Analog Devices.

The FDA-approved PocketCPR provides users with prompts to encourage a compression depth of 1.5 to 2 inches as recommended by the American Heart Association and International Liaison Committee on Resuscitation, Analog stated.

In addition, the device instructs the rescuer to push harder if the compressions are less than 1.5 inches but if good compressions are delivered, PocketCPR will respond with "good compressions." A metronome helps the user achieve the proper rate of compression, the company added.
