![]() ![]() Getting rid of crackles requires treating their cause. Although more research is needed, the study found that after the age of 45, the occurrence of crackles tripled every 10 years. Additional causesĪlthough not as common, bibasilar crackles may also be present if you have chronic obstructive pulmonary disease (COPD) or asthma.Ī 2008 study showed that lung crackles may be related to age in some asymptomatic cardiovascular patients. Interstitial lung disease usually causes bibasilar crackles. occupational or environmental exposures, such as asbestos, smoking, or coal dust.Any lung disease that impacts this area is known as interstitial lung disease. The interstitium is the tissue and space that surrounds the air sacs of the lung. Some non-cardiac causes of pulmonary edema are: This results in a backup of blood, which increases blood pressure and causes fluid to collect in the air sacs in the lungs. CHF occurs when the heart cannot pump blood effectively. People with congestive heart failure (CHF) often have pulmonary edema. Pulmonary edema may cause crackling sounds in your lungs. Smoking is the main cause of chronic bronchitis. Chronic bronchitis occurs when bronchitis doesn’t go away. Viruses, such as the cold or flu, or lung irritants usually cause acute bronchitis. The symptoms may include bibasilar crackles, a severe cough which brings up mucus, and wheezing. Bronchitisīronchitis occurs when your bronchial tubes become inflamed. Pneumonia may be mild or life-threatening. This causes a cough, difficulty breathing, and crackles. The infection causes air sacs in your lungs to become pus-filled and inflamed. Many conditions cause excess fluid in the lungs and may lead to bibasilar crackles. © 2012 by the Society for Academic Emergency Medicine.What are the causes of bibasilar crackles? The pilot data generated in this study support the concept that relative differences in respiratory sound intensity may be useful in distinguishing acute dyspnea caused by CHF, COPD, or asthma. In marked contrast, the peak I/E ratios of COPD and asthma patients were 3.4 (= 2.1) and 0.1 (IQR = 0.3 p < 0.05), respectively. In healthy volunteers and CHF patients, the ratios of vibration energy values at peak inspiration and expiration (peak I/E ratio) were 4.6 (IQR = 4.4) and 4.7 (IQR = 3.5). Compared to healthy volunteers, the geographic area ratio between the left and right lungs for asthma patients was 0.5 (IQR = 0.4 p < 0.05). The geographic area ratios between the left and right lungs for healthy volunteers and CHF and COPD patients were 1.0 (IQR = 0.2), 1.0 (IQR = 0.2), and 1.0 (IQR = 0.1), respectively. Compared to healthy volunteers and COPD patients, areas for CHF and asthma patients were smaller, at 66.9 (IQR = 9.9) and 53.9 (IQR = 15.6) kilopixels, respectively (p < 0.05). In healthy volunteers and COPD patients, the median (interquartile range ) geographical areas of the vibration energy images were similar, at 75.6 (IQR = 6.0) and 75.8 (IQR = 10.8) kilopixels, respectively (p > 0.05). Geographical area of the images and respiratory sound patterns were quantitatively analyzed. Twenty healthy subjects were also enrolled as a comparison group. Consecutive CHF (n = 22), COPD (n = 19), and asthma (n = 18) patients were imaged at the time of presentation to the emergency department (ED). Breath sound distribution was mapped to create a gray-scale sequence of two-dimensional images based on intensity of sound (vibration). Respiratory sounds throughout the respiratory cycle were captured and displayed using an acoustic-based imaging technique. The aim of this study was to evaluate in detail the distribution of respiratory sound intensity in CHF, COPD, and asthma patients during acute exacerbation. Although congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and asthma patients typically present with abnormal auscultatory findings on lung examination, respiratory sounds are not normally subjected to rigorous analysis.
