Management of brain hypoxia

Always bear in mind that brain hypoxia requires prompt treatment to reinstate the oxygen flow to the brain.

The precise mode of treatment is based on the root case and seriousness of the condition. For mild cases brought about by mountain climbing, moving to a lower altitude can help. In severe cases, emergency treatment is necessary which involves a ventilator.

In some cases, the heart requires support. Blood products are administered as well as intravenous fluids. Prompt treatment can help lessen the chances of brain damage.

Drugs are also given for blood pressure issues or to regulate the heart rate. Medications for seizure control or anesthetics might also be part of treatment.
