Fainting
In some cases, the reduction in the available oxygen for the brain is severe enough to cause fainting and other alterations of the consciousness. This typically occurs in the elderly and patients with an underlying problem, as we mentioned previously.
In some cases, additional neurological symptoms may appear, such as seizures and delirium. All of these signs and symptoms are strongly related to a lack of oxygen in the nervous system, which usually points out that the pulmonary embolism has been prolonged for too long. In these cases, it is essential to remain calm, control the symptoms of the patient in the case of delirium or seizures, and call for urgent medical attention while doing so. Most of the neurological problems associated with pulmonary embolism cause no permanent damage, but they may signal a prolonged condition that would probably cause permanent damage to the lung tissue.
