Pulmonary Flashcards
probability of pneumonia from chest x-ray infiltrate
PS4 CAT (probability of pneumonia from chest x-ray infiltrate)
Pyrexia (> 37.8) Decreased breath sounds Crackles on auscultation Absence of asthma Tachycardia (HR > 100)
Greater than 4 means 25-50% likelihood of pneumonia
causes of community-acquired pneumonia
Some HCM Raises IMPortant Heart Concerning Practices (causes of community-acquired pneumonia)
Bacterial: Streptococcus pneumonia Haemophilus influenzae Chlamydia pneumonia Mycoplasma pneumonia
Viral: Respiratory syncytial virus Influenza viruses Metapneumovirus Parainfluenza viruses
Fungal:
Histoplasmosis
Coccidiodes immitis
Pneumocystis jiroveci (immunocompromised)
bacterial causes of hospital-acquired pneumonia
GP from HELL (bacterial causes of hospital-acquired pneumonia)
Gram positive cocci (MSSA, MRSA, S. pneumonia)
Pseudomonas (Gram-negative bacilli) MOST SIGNIFICANT
Haemophilus influenza (Gram-negative coccobacilli)
Enterobacteriacae
Legionella (Gram-negative coccobacilli)
pathogens of nursing home pneumonia)
HIV is A GG, but at least you don’t have CML (pathogens of nursing home pneumonia)
Haemophilus influenza
Influenza Viruses
Anaerobes
Gram-positive cocci
Gram-negative bacilli
S. pneumonia and GNB are most significant causes.
The 3 below are rarely causes of NAP.
Chlamydia
Mycoplasma
Legionella
prognostic factors of nursing home pneumonia
You need a HD to get into RMH (prognostic factors of nursing home pneumonia)
History of Dementia
RR > 30
Acute Mental state change
HR > 125
Greater than 2 yields a 30% mortality rate.
causes of upper and lower lung fibrosis
CHARTS and COBRAS (causes of upper and lower lung fibrosis)
This mnemonic is for interstitial lung disease, not pulmonary fibrosis. Although pulmonary fibrosis does cause ILD, not all ILD are caused by pulmonary fibrosis.
Additionally, the list is incomplete as it does not include SLE, Sjogren’s as part of the causes.
Idiopathic: 40% Occupational and environmental: 26% Sarcoidosis: 10% Connective tissue disorders: 9% 4 Coal miner’s pneumoconiosis, cystic fibrosis, chronic allergic alveolitis, chronic eosinophilic pneumonitis Histiocytosis 3 Ankylising spondylitis, ABPA, alveolar haemorrhagic syndrome Radiotherapy Tuberculosis 2 Sarcoidosis, silicosis
2 Cryptogenic, other collagen vascular diseases
Other drugs BAM (bleomycin, amiodarone, methotrexate)
Bronchiectasis
Rheumatoid arthritis
3 Asbestosis, acute allergic alveolitis, acute eosinophilic pneumonitis
