7 Lungs 2 Flashcards
CBC results
Acute bronchitis: elevated lymphocytes
Bacterial pneumonia: elevated neutrophils
Auscultation results for pt with emphysema vs chronic bronchitis
Emphysema: crackles upon expiration
Chronic bronchitis: crackles upon inspiration
Klebsiella
affects alcoholics, malnourished, DM. necrotizing lobar pneumonia. Relative Bradycardia and current jelly sputum
Abnormal breath sounds
Decreased (smoker, obese, emphysema, pleural effusion), absent (collapsed lung), bronchial (loud and harsh, areas of consolidation)
Adventitious breath sounds
Ronchi, crackles, wheezing, stridor
Auscultation findings over consolidation
Egophany, bronchophony, whispered pectoriloquy
Stridor and SOB DDX
Epiglottitis–hot potato voice, high fever, drool, emergency
Foreign body–no hx of URI or fever, sudden
Retropharyngeal abscess–swelling back of throat, follow infxn
Diphtheria–grayish membrane over pharynx/larynx
Laryngotracheobronchitis
Croup. Parainfluenza virus, adenovirus, RSV
Children 6mos to 3 years. Prodrome of URI w low fever, cough then hoarse voice, seal-like cough, respiratory stridor at night
Acute bronchitis
Self limited inflammation of bronchus from viral infection. Ssx: cough > 5 days w sputum. PE: afebrile/low, wheezing, ronchi, normal percussion and transmission voice tests
Productive cough DDX
Acute bronchitis, chronic bronchitis, pneumonia, post nasal drip, GERD, asthma
Pathophysiology of typical lobar pneumonia
Stage 1: congestion
Stage 2: red hepatization
Stage 3: grey hepatization
Stage 4: resolving
Community acquired pneumonia
Risks: level of consciousness, smoking, alcohol, lung disease, malnutrition, old age, immuno compromised
Organisms: RSV, parainfluenza virus, influenza, adenovirus, S pneumoniae, H flu, S aureus, group a strep, M catarrhalis, klebsiella, legionella, M pneumoniae, Chlamydophila, P aeruginosa
Nosocomial pneumonia
Ventilator assoc, healthcare assoc (IV therapy, chemotherapy, dialysis, nursing home)
Legionella pneumophila
concomitant GI symptoms of nausea and vomiting. Outbreaks from aerosolized organisms
Sx in elderly, smokers, immunocompromised, alcoholics, pts w pre existing condition
Sputum in various bacterial pneumonias
Pneumococcus: bloody, rust colored
Pseudomonas, Haemophilus, pneumococcal: green
Anaerobic infxns: foul smelling
Klebsiella: viscid, currant jelly
Bacterial pneumonia PE findings
Look sick/pallor, high fever, tachy/bradychardia, bronchial breath sounds, Egophany, dullness, tachypnea, cyanosis, wheezes/ronchi/crackles, tactile fremitus, pleural friction rub
If bacterial pneumonia doesn’t resolve..
Comborbiites: alcoholism, COPD, CHF, CKD, malignancy, DM, HIV
Age >65 yrs, neoplastic disease
Klebsiella, legionella, S aureus, S pneumoniae, TB, fungi
Misdiagnosis of connective tissue disease, sarcoidosis, pulmonary embolism, pulmonary edema, drug induced lung disease
Viral pneumoniae SSX
Malaise, headache, myalgia, cervical LA, chest pain, sore throat, cough w scant sputum
