Two months of acclimatization to high altitude leads to an adaptation of the aerobic capacity of the myocardium, characterized by an increased ability to extract O₂ from the coronary vascular bed. An increased mitochondrial volume and activity of oxidative enzymes or improved diffusion conditions could be involved.

Providing continuous technical support and reliable test data collection for point-of-care blood gas testing is a difficult task for many laboratories.  Here we describe how the implementation of an integrated instrument control and data management system for point-of-care blood gas testing has streamlined these...

Our ability to assess the oxygenation status in critical care with a high degree of accuracy has improved as a result of recent developments in optical technology. The determination of the oxygenation status, however, remains a complex issue due to its multifaceted nature. This review discusses the definitions,...

The possibility of continuously monitoring arterial blood oxygen and carbon dioxide using heated surface electrodes on human skin was discovered in the early 1970s and made commercially available by 1976.  These devices were applied initially to premature infants in an effort to reduce the incidence of blindness due...
