Abstract EN
Quality of cardiopulmonary resuscitation (CPR) improves through the use of CPR feedback devices.
Most feedback devices integrate the acceleration twice to estimate compression depth.
However, they use additional sensors or processing techniques to compensate for large displacement drifts caused by integration.
This study introduces an accelerometer-based method that avoids integration by using spectral techniques on short duration acceleration intervals.
We used a manikin placed on a hard surface, a sternal triaxial accelerometer, and a photoelectric distance sensor (gold standard).
Twenty volunteers provided 60 s of continuous compressions to test various rates (80–140 min−1), depths (3–5 cm), and accelerometer misalignment conditions.
A total of 320 records with 35312 compressions were analysed.
The global root-mean-square errors in rate and depth were below 1.5 min−1 and 2 mm for analysis intervals between 2 and 5 s.
For 3 s analysis intervals the 95% levels of agreement between the method and the gold standard were within −1.64–1.67 min−1 and −1.69–1.72 mm, respectively.
Accurate feedback on chest compression rate and depth is feasible applying spectral techniques to the acceleration.
The method avoids additional techniques to compensate for the integration displacement drift, improving accuracy, and simplifying current accelerometer-based devices.
