====== Cerebral hypoxia ======

see [[Ischemic Stroke]]

Form of [[hypoxia]] (reduced supply of [[oxygen]]) specifically involving the [[brain]]






===== Diagnosis =====
[[Magnetic resonance spectroscopy]] ([[MRS]]): [[lactate]].

===== Treatment =====
Check ABG, respiratory rate.

Intubate any patient who has [[hypercarbia]], [[hypoxemia]], or is not localizing

===== Complications =====

The [[occipital pole]]s are particularly vulnerable to diffuse hypoxia
(( Hoyt WF, Walsh FB. Cortical Blindness with Partial Recovery Following Cerebral Anoxia from Cardiac Arrest. Arch Ophthalm. 1958; 60:1061–1069));
attested to by cases of [[cortical blindness]] after [[cardiac arrest]]
((Weinberger HA, van der Woude R, Maier HC. Prognosis of Cortical Blindness Following Cardiac Arrest in Children. JAMA. 1962; 179:126–129)).
[[Hypotension]] superimposed on compromised [[PCA]] circulation (from herniation or elevated [[ICP]]) may thus increase the risk of postgeniculate [[blindness]].
