patients found that in most patients, a BAL Ͼ240 mg/dl did not reduce one’s GCS by more than 2–3 points [13]. These studies suggest that intoxicated patients with BALs Ͻ200–240 mg/dl and a GCS of 13 or less should be evaluated for additional causes of altered mental status. For example, a patient with a GCS of 12 and a BAL of 80 mg/dl should be further evaluated for an alternative diagnosis or diagnoses. On the other hand, if a patient’s BAL is consistent with the degree of altered mental status,

Physicians should never rule in or rule out PE simply based on ECG finding.

Yet compared to the abdomen, the chest contains relatively few structures (e.g., the heart, the lungs, the great vessels, the esophagus) to consider as the source of the complaint when evaluating a patient with chest pain. In these few structures, however, there exists the potential for several life-threatening maladies, some of which unfortunately occur rather commonly. In patients with chest pain, initial attention is often devoted to establishing the presence or absence

Pitfall | Assumption that a normal ECG rules out cardiac ischemia When working through the differential diagnosis of chest pain, it is often said that the patient cannot be having an MI if ECG is normal. This is not true; in fact, no historical complaint, physical finding, or ECG pattern has a negative predictive value of 100% for MI. The patient may be less likely to be experiencing an MI if the ECG is
