Anoxia (Hypoxia) 09/13/2004 - "Acute hypoxia reduced the median oxygen partial pressure (pO(2)) dramatically (1 vs 10 mmHg in controls), whereas in chronically hypoxic tumours the pO(2) was significantly improved (median pO(2)=4 mmHg), however not reaching the control level" 07/04/1977 - "Portacaval transposition and end-to-side shunt led to a striking oxygen deficit of the liver tissue with no incidence of compensation by the hepatic artery; Oxygen supply was improved considerably by a side-to-side shunt and tissue hypoxia could be prevented by a mesenterico-caval shunt and splenocaval shunt" 01/01/1995 - "Measurement of cardiac output and clinical assessment of the patients' oxygen requirements will complete the macro picture of supply and demand and although computed indicators of hypoxia have been improved in recent years (1, 2) the definitive diagnosis of histohypoxia requires the measurement of the cellular and subcellular products of metabolic processes that are present when an inappropriate concentration of oxygen has been experienced" 09/24/1983 - "That the fall in oxygen saturation was significantly greater (p less than 0.05) in the obese non-responders suggests that central as well as mechanical factors may be important for the genesis of nocturnal hypoxia and is evidence for a disturbance of central nervous function in some obese women." 07/01/2001 - "Artery wall hypoxia noted following the creation of a PVG-to-artery anastomosis can be eliminated and artery wall oxygen tensions significantly increased by the administration of supplemental oxygen."

Chronic Obstructive Pulmonary Disease (COPD) 01/01/2004 - "STUDY OBJECTIVES: Recently, we demonstrated significantly improved baroreflex sensitivity (BRS) and autonomic balance after 31% supplemental oxygen (SuppO2) in resting patients with chronic obstructive pulmonary disease (COPD)" 01/01/2006 - "Patients with advanced COPD presented significantly greater Borg and oxygen saturation changes than patients with less severe disease (p = 0.02 and p = 0.001, respectively)" 10/01/2004 - "CONCLUSION: High flows of humidified oxygen improved exercise performance in patients with COPD and severe oxygen dependency, in part by enhancing oxygenation." 01/01/1991 - "The absolute oxygen uptake at each RPE was significantly greater in the healthy subjects than in the patients with COPD" 01/01/1989 - "Four COPD patients, who had a decrease over 5 mmHg in arterial oxygen tension (PaO2) at maximal exercise (group A), had significantly greater slope (0.45 +/- 0.14%/ml/min, mean +/- S.E.) than in five COPD patients (group B, 0.14 +/- 0.05), who did not have a decrease over 5 mmHg in PaO2 at maximal exercise" Order ALL the reference details at left...
3.	Neoplasms (Cancer) 05/01/1992 - "Krogh cylinder models, which incorporate these data for perivascular oxygen tension, along with morphometric data obtained from the same tumor model suggest that hypoxic regions will exist between tumor vessels in the tumor center unless O2 consumption rates are well below 0.6 ml/100 g/min. The low perivascular measurements observed near the tumor center combined with the theoretical considerations suggest, for this model at least, that tissue oxygenation may best be improved by increasing red cell velocity and input pO2 and reducing oxygen consumption" 03/15/2007 - "Although the tumors did not respond to oxygen inhalation, each tumor had a different pO(2), and there was a clear trend between
