Oxygen and Stroke, Benefit?

An interesting article about O2 and stroke

Oxygen Shows Promise as a Stroke Treatment - Forbes

This article touts the use of oxygen by mask as an early adjunct to treatment of stroke (not HBOT).

A recent Cochrane review is as follows:
"Little evidence that stroke patients benefit from hyperbaric oxygen therapy.

Hyperbaric oxygen therapy (HBOT) is a treatment designed to increase the supply of oxygen to the part of the brain affected by stroke and reduce the extent of irreversible damage. HBOT involves people breathing pure oxygen in a specially designed chamber (such as those used for deep sea divers with the bends). Our review found only three randomised trials with a limited number of participants. Too few patients have been studied to say whether or not HBOT decreases the chance of dying and only one trial suggested any improvement in the ability to do everyday tasks. Overall, there is currently little evidence to support the use of HBOT for stroke patients."
