Effects On Microcirculation

From the above, we can conclude that the precise regulatory mechanisms controlling oxygen and blood supply to organs is related to tissue metabolism. These mechanisms come into play very quickly and are controlled by the respective organs themselves. This is largely independent from the autonomic nervous system and is also unrelated to hormonal regulation via cardio-circulatory adjustment mechanisms (renin-angiotensin system, circulating catecholamines). These features tend to point to regulating mechanisms either at a local level (organs) or rather even at a microcirculatory level.

Thus it is at the microcirculatory level that the action of high pressures of oxygen should be studied.
