Assessing the variability in respiratory acoustic thoracic imaging (RATHI).

Charleston-Villalobos S1, Torres-Jiménez A2, González-Camarena R3, Chi-Lem G4, Aljama-Corrales T2.Author information 1Electrical Engineering Department, Universidad Autonoma Metropolitana, Mexico City 09340, Mexico. Electronic address: schv@xanum.uam.mx.2Electrical Engineering Department, Universidad Autonoma Metropolitana, Mexico City 09340, Mexico.3Department of Health Science, Universidad Autonoma Metropolitana, Mexico City 09340, Mexico.4National Institute of Respiratory Diseases, Mexico City 14080, Mexico.AbstractMultichannel analysis of lung sounds (LSs) has enabled the generation of a functional image for the temporal and spatial study of LS intensities in healthy and diseased subjects; this method is known as respiratory acoustic thoracic imaging (RATHI). This acoustic imaging technique has been applied to diverse pulmonary conditions, but it is important to contribute to the understanding of RATHI characteristics, such as acoustic spatial distribution, dependence on airflow and variability. The purpose of the current study is to assess the intra-subject and inter-subject RATHI variabilities in a cohort of 12 healthy male subjects (24.3±1.5 years) using diverse quantitative indices. The indices were obtained directly from the acoustic image and did not require scores from human raters, which helps to prevent inter-observer variability. To generate the acoustic image, LSs were acquired at 25 positions on the posterior thoracic surface by means of airborne sound sensors with a wide frequency band from 75up to 1000Hz under controlled airflow conditions at 1.0, 1.5 and 2.0L/s. To assess intra-subject variability, the degree of similitude between inspiratory acoustic images was evaluated through quadratic mutual information based on the Cauchy-Schwartz inequality (ICS). The inter-subject variability was assessed by an image registration procedure between RATHIs and X-ray images to allow the computation of average and variance acoustic image in the same coordinate space. The results indicated that intra-subject RATHI similitude, reflected by ICS-global, averaged 0.960±0.008, 0.958±0.008 and 0.960±0.007 for airflows of 1.0, 1.5, and 2L/s, respectively. As for the inter-subject variability, the variance image values for three airflow conditions indicated low image variability as they ranged from 0.01 to 0.04. In conclusion, the assessment of intra-subject and inter-subject variability by similitude indices indicated that the acoustic image pattern is repeatable along different respiratory cycles and across different subjects. Therefore, RATHI could be used to explore different aspects of spatial distribution and its association with regional pulmonary ventilation.

The heat is on … thermal epiglottitis as a late presentation of airway steam injury.

Kudchadkar SR1, Hamrick JT1, Mai CL2, Berkowitz I1, Tunkel D3.Author information 1Division of Pediatric Anesthesiology and Critical Care Medicine, Department of Anesthesiology and Critical Care Medicine, Johns Hopkins University, Baltimore, Maryland.2Department of Anesthesia, Critical Care and Pain Medicine, Massachusetts General Hospital, Harvard University, Boston, Massachusetts.3Division of Pediatric Otolaryngology, Department of Otolaryngology and Head and Neck Surgery, Johns Hopkins University, Baltimore, Maryland.AbstractBACKGROUND: Thermal epiglottitis is a rare but potentially life-threatening disease. Diagnosis requires a thorough history and high clinical level of suspicion, particularly in children. Thermal epiglottitis from steam inhalation can have a slow onset without oropharyngeal signs of thermal injury, findings that can hide the clinical diagnosis.

Respiratory sounds in healthy people: A systematic review.

Electronic address: alao@ua.pt.2School of Health Sciences, University of Aveiro (ESSUA), Aveiro, Portugal; Unidade de Investigação e Formação sobre Adultos e Idosos, Porto, Portugal. Electronic address: amarques@ua.pt.AbstractBACKGROUND: There is a lack of systematised information on respiratory sounds of healthy people. This impairs health professionals from differentiating respiratory sounds of healthy people from people with respiratory diseases, which may affect patients' diagnosis and treatment. Therefore, this systematic review aimed to characterise respiratory sounds of healthy people.
