Pneumoconioses and Vaping Flashcards
chronic, fibrotic lung diseases caused by the inhalation of inorganic particles
pneumoconiosis
what would spirometry show for pneumoconiosis?
restrictive
what are the general treatments for pneumoconiosis? (4)
supplemental O2
cough suppressant
bronchodilators
ICS
where is coal worker’s pneumoconiosis most prominent in the lungs?
upper lobes
how do patients with simple coal worker’s pneumoconiosis present?
asymptomatic
coal deposits in the lung tissue that weakens alveoli leading to alveolar dilation and emphysematous changes
simple coal worker’s pneumoconiosis
accumulation of macules that turn into nodules with sterile caseating lesions
complicated coal worker’s pneumoconiosis
inhalation of silica particles that leads to formation of small rounded opacities called silicotic nodules with eggshell calcification
silicosis
type of silicosis that is asymptomatic
simple silicosis
silicosis with large conglomerate densities of nodules in upper lungs, dyspnea, with spirometry showing obstructive or restrictive pulmonary lung dysfunction
complicated silicosis
what does silicosis increase the risk for?
pulmonary tuberculosis
a patient presents with worsening/progressive dyspnea, inspiratory crackles, and +/- digital clubbing with cyanosis. what are they likely experiencing?
asbestosis
what would be seen in a CXR of a patient with asbestosis?
pleural plaques - lower lung and borders
what is the imaging of choice for asbestosis?
Chest CT
a chest CT that shows lung streaking at lung bases, opacities or various sizes, honeycomb changes, and pleural plaques indicates what?
asbestosis
