From January 1980 to August 1983, 213 patients with carbon monoxide poisoning were seen; 131 received hyperbaric oxygen and had no sequelae. Eighty-two patients were treated with normobaric oxygen; ten (12.1%) returned with clinically significant sequelae. The specific neurological sequelae included headaches, irritability, personality changes, confusion, and loss of memory. This recurrent symptomatology developed within one to 21 days (mean, 5.7 days) after the initial exposure, although no reexposure occurred. These recurring symptoms resolved rapidly with hyperbaric oxygen therapy. We recommend that hyperbaric oxygen therapy be used whenever CO poisoning symptoms recur.

    Neuroimaging is often abnormal and may correlate with the development of DNS,145 although DNS is also reported in patients with normal neuroimaging.146 The true incidence of DNS is difficult to determine with estimates ranging from less than 1% up to 47% of patients after CO poisoning.120,141–143,146–150 The large variability in incidence is at least partially explained by a lack of consistency in defining DNS using either clinical, subclinical (ie, neuropsychometric testing results), self-reported, or combination criteria.

    Unfortunately, these signs are not always present. Several studies have evaluated the prevalence of CO symptoms and found that headache (91% of patients), dizziness (77%), and weakness (53%) are the most commonly reported symptoms.45–47 The classic findings of cherry red lips, cyanosis, and retinal hemorrhages are predominantly found in patients who are in extremis and tend to be rare in patients who present to the medical system.48
