-Tx: abx, goal directed,
4) PE
-lungs: clear
-CXR: clear/Westrmrk/Hmptn
-Tx: ECG, D-dimer and/or spiral CT; anticoagulate/thrombolise
5) Pneumo/Hemo-Thorax
-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, +/- thrombolitics
- Consider ABG
