This vasculature is, however, primitive, and parts of the tumour are poorly oxygenated. Relation of temperature, gas tension, and hydrostatic pressure to the formation of gas bubbles in extracorporeal oxygenated blood. The water does not stratify and is well oxygenated throughout the year. This unit was deposited during a time when the lake was oxygenated throughout the water column and no water-column stratification was present. The evaporation of these oceans, and subsequent escape of hydrogen, most likely resulted in an oxygenated atmosphere. The increased supply of oxygenated blood overcompensates the demand of oxygen and leads to an increase in oxygen level as a response to increased cor tical activity. We also encourage discontinuation of life support in resuscitated infants who fail to oxygenate adequately (less than 90% oxygen saturation) despite surfactant, mechanical ventilation, and cardiovascular support. This might not be without risk, considering die possible formation of oxygen radicals or possible cerebral vasoconstriction due to preferential flow of highly oxygenated blood towards die brain. This decrease in pulmonary vascular resistance could be explained by the fact that warm oxygenated blood was continuously being delivered to the right heart during modified ultrafiltration. Hypoxic cells are up to three times more resistant to radiation than oxygenated cells15 and are a potential cause of local failure of radiotherapy.
