Does normocapnia improve cerebral oxygen delivery during conventional oxygen therapy in carbon monoxide-exposed research subjects?
If severely poisoned patients respond like our research subjects, maintaining normocapnia during initial hyperoxic treatment of carbon monoxide poisoning may lead to increased oxygen delivery to the brain. Determining the effect of such a change in conventional treatment on outcome requires clinical studies.
In patients with stable angina pectoris, preserved ejection fraction, and reversible ischaemia assessed by SPECT, echocardiographic colour TDI performed at rest reveals impaired cardiac function. The impairment of the cardiac function seems to be evident only in patients with a true-positive SPECT and colour TDI may therefore increase its diagnostic value.
