Background
Clinical Features
Emergent Pattern Recognition
| Diagnosis | Lungs | CXR | ECG | Treatment | Contraindicated |
| Pulmonary Edema | Bilateral rales | Interstitial fluid | Normal/abnormal | R/O AMI, lasix, nitrates, ACEi, BIPAP | IVF; ?albuterol; ?Beta-blockers |
| Bronchoconstriction | Wheezes | Clear/hyperinflated | Normal/pulmonary strain | Albuterol, atrovent, steroids, consider anaphylaxis (epi) | Beta-blockers; ?aspirin |
| Pneumonia | Focal ronchi/decreased breath sounds | Infiltrate/effusion | Normal | IVF, antibiotics | Rate control; diuresis |
| Pulmonary embolism | Clear | Clear (most) or Westrmark/Hampton hump | Normal/S1Q3T3 | Anticoagulate/thrombolytics | Rate control |
| Pneumothorax/Hemothorax | Unequal | Pneumo/hemo | Normal | Needle thoracentesis/chest tube | Rate control |
| Dysrythmia | Clear/pulmonary edema | Clear/pulmonary edema | Abnormal | Type dependent | Albuterol; ?IVF |
| ACS | Clear/pulmonary edema | Clear/pulmonary edema | Normal/abnormal | Aspirin; nitrates, anticoagulation, ?beta-blockers, +/- thrombolytics | Albuterol; ?IVF |
