Basal crackles are crackles apparently originating in or near the base of the lung. Bibasal crackles, also called bilateral basal crackles, are crackles heard at the bases of both the left and right lungs. Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration.
Fine crackles Coarse crackles [13] [14] Several sources will also refer to "medium" crackles, as a crackling sound that seems to fall between the coarse and fine crackles. Crackles are defined as discrete sounds that last less than 250 ms, while the continuous sounds (rhonchi and wheezes) last approximately 250 ms.
Basilar may refer to: Basilar artery; Basilar artery migraines; Basilar crackles; Basilar crest; Basilar membrane; Basilar part of occipital bone; Basilar part of pons;
Possible medium, late, or pan-inspiratory crackles; Vocal resonance is increased. Here, the patient's voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to the healthy lung where speech sounds muffled. A pleural rub may be present. [4] A lower P A O 2 than calculated in the ...
Dry, inspiratory bilateral basal crackles on auscultation (a crackling or popping sound in the lungs during inhalation). [3] [12] [13] Clubbing of the digits, a disfigurement of the finger tips or toes (see image) Abnormal pulmonary function test results, with evidence of restriction and impaired gas exchange.
Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung.
Depending on the type of alveolar lung disease, the listener may hear "crackles" that indicate an excess of fluid in the lungs or an absence of lung sounds in certain regions which may indicate poor ventilation due to consolidation of pus or fibrosis. [6] A pulse oximeter is a device that measures the amount of oxygen available in the blood ...
During external examination, clubbing (swelling of fingertip tissue and increase in angle at the nail bed), [14] and basal crackles may be observed. For hypersensitivity pneumonitis many diagnoses take place through the focus of blood test, chest x-rays, and depending on severity of infection doctors may recommend a bronchoscopy.
