844, 855, 866, 877, 888 and 800. No advantage to 8YY vs. using toll-free number as the latter is broad enough to include domestic toll-free services in other countries which number things differently. K7L (talk) 04:21, 31 October 2013 (UTC)
From Wikipedia, the free encyclopedia. The arteriovenous oxygen difference, or a-vO2 diff, is the difference in the oxygen content of the blood between the arterial blood and the venous blood. It is an indication of how much oxygen is removed from the blood in capillaries as the blood circulates in the body.he usual unit for a-vO 2 diff is millilitres of oxygen per 100 millilitres of blood (mL/100 mL), however, particularly in medical uses, other units may be used, such as micro moles per millilitre (Î¼mol/mL).
ECMO (Extracorporeal Membrane Oxygenation) is a procedure that uses a machine to take over the work of the lungs and sometimes the heart.CMO will not heal your childâs heart or the lungs, but it will allow time for them to rest and recover. Your child can be on ECMO for several days to a few weeks. When the heart or the lungs have healed and can work on their own, the support from ECMO is gradually removed.
