Exploring EMD for Lung Crackle Detection

چکیده
This paper presents a two-stage crackle detection algorithm combining Empirical Mode Decomposition (EMD) and a simple energy peak detector. A discussion is presented of the main issues arising in the implementation of the EMD stage and the solutions adopted. The algorithm was implemented in MATLAB® and preliminarily tested on an annotated 10-second respiratory sound file, without any prior systematic training. Applying the energy peak detection to the intrinsic mode function of order 3 (IMF3) generated by the EMD stage, an 87% F performance index was achieved.

Auditory detection of simulated crackles in breath sounds.
BACKGROUND Computerized analysis of breath sounds has relied on human auditory perception as the reference standard for identifying crackles. In this study, we tested the human audibility of crackles by superimposing artificial clicks on recorded breath sounds and having physicians listen to the recordings to see if they could identify the crackles. OBJECTIVES To establish the audibility of s...
متن کاملCrackle Pitch Rises Progressively during Inspiration in Pneumonia, CHF, and IPF Patients
Objective. It is generally accepted that crackles are due to sudden opening of airways and that larger airways produce crackles of lower pitch than smaller airways do. As larger airways are likely to open earlier in inspiration than smaller airways and the reverse is likely to be true in expiration, we studied crackle pitch as a function of crackle timing in inspiration and expiration. Our goal...
متن کاملAre crackles an appropriate outcome measure for airway clearance therapy?
BACKGROUND There is an urgent need to develop new outcome measures for respiratory therapy, to evaluate its effectiveness. Adventitious sounds generated from the lungs (crackles and wheezes), can now be quantified and characterized objectively with computer technology. To our knowledge, this is the first reported study designed to assess any change in lung crackles before and after a single se...
متن کاملCrackle: A Dynamic Mobile Multitouch Topology for Exploratory Sound Interaction
This paper describes the design of Crackle, a interactive sound and touch experience inspired by the CrackleBox. We begin by describing a ruleset for Crackle’s interaction derived from the salient interactive qualities of the CrackleBox. An implementation strategy is then described for realizing the ruleset as an application for the iPhone. The paper goes on to consider the potential of using C...
متن کاملDetection of inspiratory recruitment of atelectasis by automated lung sound analysis as compared to four-dimensional computed tomography in a porcine lung injury model.
BACKGROUND Cyclic recruitment and de-recruitment of atelectasis (c-R/D) is a contributor to ventilator-induced lung injury (VILI). Bedside detection of this dynamic process could improve ventilator management. This study investigated the potential of automated lung sound analysis to detect c-R/D as compared to four-dimensional computed tomography (4DCT). METHODS In ten piglets (25 ± 2 kg), ac...
