8 Lungs Part 3 Flashcards
Interstitial Lung Dz PE
Crackles, may have pulmonary HTN
PFT shows restrictive ventilatory pattern
Clinical features of interstitial lung dz
Insidious/progressive dyspnea, persistent non productive cough
MAY have hemoptysis, musculoskeletal pain, weakness, fatigue, fever, photsensitivity
Hypersensitivity pneumonitis
Extrinsic allergic alveolitis. After inhalation of dusts, chemicals in sensitized patient–>granulomatous inflammation. 4-6hrs after exposure.
Hx questions for pt with HSN pneumonitis
Bird fancier, move to new home/school, hx of recurrent pneumonia, water damage, hot tub, other people with sxs, better on vacay?
Ssxs acute hsn pneumonitis
Acute onset, fever, chills, dry cough, chest tightness, malaise, look sick, tachypnea, crackles, dyspnea. NO wheezes.
Resolves in 12 hrs
Ssxs subacute hsn pneumonitis
Gradual onset, cough, dyspnea, fatigue, anorexia, weight loss, I’ll appearance, tachypnea, crackles
Ssxs Chronic hsn pneumonitis
Insidious onset, cough, progressive dyspnea, fatigue, weight loss, exercise intolerance, crackles, clubbing, inspiratory SQUWAK
Eosinophilic pulmonary disorders
Allergic response w accumulation of eosinophils in lung interstitium. Get TRAVEL HX
Rxn to filaria, drugs, parasites, fungi, inhaled toxins
Idiopathic interstitial pneumonias
Unknown but common in smokers. Present similarly, suspect on hx, lead to restrictive lung changes, seen on CXR
Drug induced ILD
Antis, chemo, anti arrhythmics, statins, coke, heroin, anticoagulants
Pneumoconiosis
Inhalation of inorganic/mineral dusts.
Asbestosis (mining, milling, manufacture)
Silicosis (mining, pottery, sand blasting, brick making)
Anthracosis (black lung)
Berylliosis (fluorescent light bulbs, ceramics, chemical plants, electronics, aerospace)
Miscellaneous (talc, iron, tin oxide, cadmium, aluminum, cotton)
Occupational asthma
SOB, chest tightness, wheezing, cough, (sneezing, d/c)
Detected using a peak flow meter at work
Irritant gas inhalation
Severe burning of eyes, nose, trachea, bronchi w cough, hemoptysis, wheezing
Due to: industrial accidents, chloramine, cyanide, CO, methane, chlorine, hydrogen sulfide
Air pollution related illness
Nitrogen/sulfur oxides, ozone, CO, lead, VOC, CFCs
*exacerbation in asthmatics, COPD
Wegener’s granulomatosis
Pulmonary vasculitides. Autoimmune–affects lung, nose, kidneys
