Several studies have revealed a positive effect of treatment of ischaemic wounds and flaps with hyperbaric oxygen. We studied the effect of 100% oxygen (2.4 ATA) for 90 min daily on different phases of healing ischaemic and normal incisional wounds in rats. Hyperbaric oxygen on day 0-3 significantly increased almost all the force parameters of ischaemic flap wounds by 41-57% after 10 days of healing. On the other hand, when the treatment was continued until day 9 the positive effect on the wound healing was abolished. Furthermore, when hyperbaric oxygen was given on days 4-9 there was a tendency towards a decrease in the biomechanical parameters. Hyperbaric oxygen had no effect on the healing of normal incisional wounds.

UI	MeSH Term	Description	Entries
D007511	Ischemia	A hypoperfusion of the BLOOD through an organ or tissue caused by a PATHOLOGIC CONSTRICTION or obstruction of its BLOOD VESSELS, or an absence of BLOOD CIRCULATION.	Ischemias

D006931	Hyperbaric Oxygenation	The therapeutic intermittent administration of oxygen in a chamber at greater than sea-level atmospheric pressures (three atmospheres). It is considered effective treatment for air and gas embolisms, smoke inhalation, acute carbon monoxide poisoning, caisson disease, clostridial gangrene, etc. (From Segen, Dictionary of Modern Medicine, 1992). The list of treatment modalities includes stroke.
