Cyanide Poisoning Evaluation
The evaluation of cyanide poisoning is based on an urgent history and physical examination. Any person who collapses after exposure to fire smoke or industrial chemicals may have inhaled cyanide.
Physical findings in someone with cyanide poisoning may include:
- Ataxia (difficulty walking)
- Bright red retinal arteries
- Cardiac arrhythmias
- Cherry-red skin
- Dilated pupils
- Low blood pressure
- Rapid breathing
- Rapid pulse
Cyanide poisoning is so deadly, that treatment must not be delayed by test results.
Tests that may be used to evaluate cyanide poisoning include:
