A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
Well-demarcated, nodular lesions ranging 2–5 mm in pulmonary parenchyma. Type II pneumocytes without nuclear atypia lined thickened alveolar septa and proliferated papillary structures. Enlarged cuboidal cells lining mildly thickened alveolar septa. [11] Enlarged cuboidal cells have abundant, eosinophilic cytoplasm and large, round nuclei. [12]
Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [ 1 ]
Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
Mucociliary clearance (MCC), mucociliary transport, or the mucociliary escalator describes the self-clearing mechanism of the airways in the respiratory system. [1] It is one of the two protective processes for the lungs in removing inhaled particles including pathogens before they can reach the delicate tissue of the lungs.
In pulmonary consolidations and infiltrates, air bronchograms are most commonly caused by pneumonia or pulmonary edema (especially with alveolar edema). [2] [3] Other potential causes of consolidations or infiltrates with air bronchograms are: [2] Pulmonary edema; Non-obstructive atelectasis; Severe interstitial lung disease; Pulmonary infarct
A respiratory examination, or lung examination, is performed as part of a physical examination, [1] in response to respiratory symptoms such as shortness of breath, cough, or chest pain, and is often carried out with a cardiac examination.
Pulmonary drug delivery is a route of administration in which patients use an inhaler to inhale their medications and drugs are absorbed into the bloodstream via the lung mucous membrane. This technique is most commonly used in the treatment of lung diseases, for example, asthma and chronic obstructive pulmonary disease (COPD).
