Rare: Meigs’ syndrome (benign ovarian tumour, ascites, pleural effusion)Ĭommon: infection (parapneumonic, tuberculosis), malignancy Less common: hypoalbuminemia, nephrotic syndrome, peritoneal dialysis, hypothyroidism 1 TypeĬommon: ‘the failures’: heart failure, cirrhosis (liver failure) An overview of the causes of pleural effusions. Fluid accumulates due to increased pleural and capillary permeability. Transudates have a low protein level of 35g/L. Pleural effusions are usually classified as transudative or exudative. Anatomy of the chest wall and pleural membranes. Pleural effusions occur when fluid accumulates in the pleural space. The serous fluid allows the visceral and parietal pleura to slide over each other during respiration and creates surface tension between the two layers. The potential space between the visceral and parietal pleura contains a small amount of lubricating serous fluid. This is a serous membrane divided into the visceral pleura (lines the lungs) and parietal pleura (lines the internal thoracic cavity). The lungs are surrounded by the pleural membrane.

Do you have an easy acronym or pearl for remembering breath sounds, or some test-taking strategies to share?īreath Sounds Reference Hinkle, J. Reviewing what you know and thinking about each response choice can help you focus in on the correct answer. During lung auscultation, crackles are heard in pulmonary fibrosis, which is choice B. There would be loss of breath sounds over the area of a pneumothorax as there is no air movement in the area of auscultation. In general, there are not specific adventitious breath sounds associated with neuromuscular disorders.Ī pneumothorax is a collapsed lung. Diaphragmatic weakness can lead to hypoventilation chest wall muscle weakness can lead to ineffective cough and upper airway muscle weakness can lead to difficult swallowing and ineffective clearing of upper airway secretions. Neuromuscular disorders can cause respiratory problems through several pathways as the muscles responsible for breathing are affected. The crackles are the result of the snapping open of collapsed, stiff alveoli. This may be hard to distinguish from congestive heart failure. The most common adventitious breath sound associated with pulmonary fibrosis is fine bibasilar crackles. This scarring leads to thickness and stiffness in the lungs. Pulmonary fibrosis is a form of interstitial lung disease in which scarring (or fibrosis) is the hallmark clinical feature. For testing purposes, however, expiratory wheezes are associated with asthma. Initially the wheezes are expiratory but depending on confounding factors or worsening clinical symptoms, there may be inspiratory wheezes, rhonchi or crackles. As air moves through these narrowed airways, the primary lung sound is high-pitched wheeze. This response is triggered by an irritant, allergen, or infection. The resulting physiologic response in the airways is bronchoconstriction and airway edema. AsthmaĪsthma is a condition mediated by inflammation. In this instance, it would be helpful to go through each clinical condition separately and predict what you may hear on auscultation. Now, let’s think about test-taking strategies.
