- Chest x-ray
- EKG (electrocardiogram, or heart tracing)

Outlook (Prognosis)
How well the person does depends on the severity of the overdose and how quickly treatment is received. If the proper narcotic antagonist (drug to counteract the effects of narcotics) can be given, recovery from an acute overdose occurs within 24 to 48 hours. However, if there has been prolonged coma and shock (damage to multiple internal organs), a more serious outcome is possible.
Acute
Acute means sudden or severe. Acute symptoms appear, change, or worsen rapidly. It is the opposite of chronic.
