- Breathing support, including tube through the mouth into the lungs and breathing machine (ventilator)
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (by IV)

Outlook (Prognosis)
How well someone does depends on how much salicylate is in the blood and how quickly treatment is received. The faster the medical help is given, the better the chance is for recovery.
Most people can recover if the effect of the salicylate can be stopped.
Internal bleeding is possible, and blood transfusion may be needed. Endoscopy, or passing a tube with a camera through the mouth into the stomach, may be needed to stop internal bleeding.
Methyl salicylate is the most poisonous form of the salicylate type of chemicals.
