The mean intensity and median frequency of normal lung sounds were significantly higher during standardized breathing than during spontaneous breathing, both at inspiration (23.1 dB vs 20.1 dB and 391.6 Hz vs 367.3 Hz) and expiration (20 dB vs17.6 dB and 376.3 Hz vs 355 Hz). Nine subjects were identified with both methods (kappa = 0.32). Expiratory wheezes were heard in 18 subjects (15.5%) during spontaneous breathing and in 23 subjects during standardized breathing (19.8%). Only 5 subjects were identified with both methods (kappa = 0.13). Lung sounds.RESULTS: Inspiratory crackles were heard in 19 subjects (16.4%) during spontaneous breathing and in 18 subjects during standardized breathing (15.5%). Auscultation a method of physical examination of the lungs. You can learn more about how we ensure our content is accurate and current by reading our editorial policy.

The condition can occur as a result of a viral, bacterial, or fungal infection. Pneumonia is an infection in one or both lungs that causes the alveoli to fill with pus or fluid. Various health conditions can cause abnormal lung sounds. It indicates damage to the air sacs within the lungs, which are called the alveoli. lung damage resulting from the condition bronchiectasisĪmphoric respiration is a type of abnormal bronchial breathing that creates a strong reverberating sound with high pitched overtones.Doctors may hear cavernous breath sounds in a person who has one of the following conditions: Mediastinal tumor: This tumor develops within the mediastinum, which is the area of the chest that separates the lungs.Ĭavernous breath sounds are low pitched bronchial breath sounds.

Atelectasis: People may refer to this as the collapse of a lung or part of a lung.Pulmonary fibrosis: The hallmarks of this lung disease are damage to and scarring of the lung tissue.Pleural effusion: This condition occurs due to a buildup of excess fluid in the tissue layers surrounding the lungs.Consolidation: Consolidation is the medical term for when air spaces within the lungs fill with liquid.The following conditions can produce tubular breath sounds: Tubular breath sounds are a type of high pitched bronchial breath sound.
