Therefore the authors proved that crackles are generated and not limited in fully collapsed lung areas. It is worth noting that the significant correlation between intratidal recruitment measured with dynamic CT and the degree of crackles in the sound analysis suggests that air passage through atelectasis as well as poorly aerated areas is crucial for generating lung crackle sounds. In addition to the spectral analysis and the CT exams they further confirmed their findings by conventional interpretation of the lung sounds by experienced physicians. Standard CT assessment of lung aeration was performed to validate these findings. The objective of the study was to develop a simple tool to use lung sound analysis for detection of lung injury and alveolar recruitment. report a nicely performed analysis of the spectral characteristics of lung sounds. In this issue of Intensive Care Medicine, Dr. Secondary to its role in routine physical examination, the analysis of lung sounds can be used in the intensive care setting to gather information about the performance and efficiency of mechanical ventilation prior to or instead of more invasive radiological procedures like chest X-rays or computer tomography (CT). Obtaining and interpreting lung sounds and especially adventitious sounds are a true art. Although auscultation is considered to be a very useful bedside tool, its major limitations are high interobserver variability, difficult description and documentation of findings, and the high dependency on individual expertise in acquiring and interpreting auscultation findings. Despite all technical advances in recent years, auscultation provides both useful physiological information and close patient–physician interaction. Even today, the stethoscope represents a symbol for physicians of all specialties. In 1819 the French physician René-Théophile-Hyacinthe Laennec (1781–1826) published his milestone book De l’Auscultation Médiate ou Traité du Diagnostic des Maladies des Poumons et du Coeur introducing the stethoscope as a diagnostic tool for the bedside assessment of respiration. Assessing the pulmonary function by physical examination is as old as the field of respiratory medicine.
