5 Crucial Characteristics of an Expert Witness Consultant in Carbon Monoxide Toxicity

  1. Experience with the clinical presentation of Carbon Monoxide toxicity that range from headache, flu like symptoms to seizure, movement disorders and death but may mimic many common illnesses.
  2. Familiarity with the assessment of CO toxicity; carboxyhemoglobin (HbCO) levels, its half- life and how this is affected by oxygen via nasal cannula and hyperbaric treatments; as well as the fact that smokers may have baseline elevation of HBCO
  3. Understanding that when HBCO is abnormal, presentations may vary depending on preexisting health conditions and that prognosis is not always associated with higher levels.
  4. Awareness that CO toxicity may involve many organ systems, heart, kidney and brain.
  5. Understanding about how to formulate a differential diagnosis, determine causation by considering chronology; past medical, occupational, family and social history; other explanations for a medical presentation, and how confirmatory examination, neurophysiological and neuropsychological testing may be used in this process.
