Background

Diagnosis

Emergent Pattern Recognition

  1. Pulmonary Edema
    • lungs: b/l rales
    • CXR: interstitial fluid
    • Tx: ECG (R/O AMI), lasix, nitrates, ACE, BIPAP
  2. Bronchoconstriction
    • lungs: wheezes
    • CXR: neg/hyperinflated
    • Tx: albuterol, atrovent, steroids, consider anaphylaxis (epi)
  3. Pneumonia
    • lungs: focal ronchi/dec BS
    • CXR: infiltrate/effusion
    • Tx: abx
  4. PE
    • lungs: clear
    • CXR: clear/Westrmrk/Hmptn
    • Tx: ECG, D-dimer and/or CT; anticoagulate/thrombolytics
  5. Pneumothorax/Hemothorax
    • lungs: unequal
    • CXR: pneumo/hemo
    • Tx: needle/chest-tube
  6. Dysrythmia
    • lungs: clear/pulm edema
    • CXR: clear/pulm edema
    • ECG: abnl
    • Tx: rate dependent
  7. Cardiac Ischemia
    • lungs: clear/pulm edema
    • CXR: clear/pulm edema
    • ECG: nl/abnl
    • Tx: B-block, nitrates, anticoag, +/- thrombolytics
