Lacking the capacity to store oxygen, the human organism depends on having an unimpaired and continuous supply of oxygen for its survival. Life-threatening disturbances can be encountered by the clinician at any step in the oxygen cascade from ambient air to tissue metabolism. It is therefore necessary for the mechanisms of oxygen uptake, transport, distribution and diffusion into tissues as well as the unaffected cellular metabolism to be well understood and monitored. An international symposium focusing on these issues was held in Münster, FRG, May 11-12, 1990. This book contains the lectures held at the symposium, and thus provides an excellent basis for further discussion.
