Efficacy of Feed Forward and Feedback Signaling for Inflations and Chest Compression Pressure During Cardiopulmonary Resuscitation in a Newborn Mannequin

Abstract

Background: The objective of the study was to evaluate a device that supports professionals during neonatal cardiopulmonary resuscitation (CPR). The device features a box that generates an audio-prompted rate guidance (feed forward) for inflations and compressions, and a transparent foil that is placed over the chest with marks for inter nipple line and sternum with LEDs incorporated in the foil indicating the exerted force (feedback).

Methods: Ten pairs (nurse/doctor) performed CPR on a newborn resuscitation mannequin. All pairs initially performed two sessions. Thereafter two sessions were performed in similar way, after randomization in 5 pairs that used the device and 5 pairs that performed CPR without the device (controls). A rhythm score was calculated based on the number of CPR cycles that were performed correctly.

Results: The rhythm score with the device improved from 85 14 to 99 2% (P < 0.05). In the control group no differences were observed. The recorded pressures with the device increased from 3.1 1.6 to 4.9 0.8 arbitrary units (P < 0.05). The second performance of the teams showed significant better results for the group with the CPR device compared to the controls.

Conclusion: Feed forward and feedback signaling leads to a more constant rhythm and chest compression pressure during CPR.
