How to Treat Carbon Monoxide Poisoning?

Things to note:
  • Remove patient from toxic conditions.
  • Deep comatose patients may need ventilation.
  • Hyperbaric oxygen therapy was not demonstrated to be beneficial in a Cochrane review.

Medical Treatment:
Give 100% oxygen using facemask. For seizures:
  • Slow IV Diazepam, 10 mg.

Medical Treatment:
  • If you think you have been exposed to low carbon monoxide levels, seek medical advice from your GP.
  • Your symptoms will often indicate whether you have carbon monoxide poisoning, but the amount of carboxyhemoglobin in your blood is confirmed by a blood test. A level of 30% indicates severe exposure.
  • Mild carbon monoxide poisoning usually does not require hospital treatment, but you still need to seek medical advice.
Standard oxygen therapy
  • If you have been exposed to a high level of carbon monoxide or have symptoms that suggest exposure, standard oxygen therapy will be needed in the hospital.
  • You will receive 100% oxygen through a tight-fitting mask (normal air contains around 21% oxygen).
  • Breathing in concentrated oxygen enables your body to replace carboxyhemoglobin quickly.
  • Therapy will continue until your levels of carboxyhemoglobin reduce to less than 10 %.
Hyperbaric oxygen therapy
  • Hyperbaric oxygen therapy (HBOT) floods the body with pure oxygen, helping it overcome the oxygen shortage caused by carbon monoxide poisoning.
  • There is currently insufficient evidence of HBOTs long - term effectiveness to treat severe cases of carbon monoxide poisoning.
  • Standard oxygen therapy is usually the recommended treatment option.
  • In certain situations, HBOT may be recommended - for example, if extensive exposure to carbon monoxide has occurred and nerve damage is suspected.
The amount of time it takes to recover from carbon monoxide poisoning will depend on how much carbon monoxide you have been exposed to and how long you have been exposed to it.
