So, what does blood oxygen saturation actually mean? In short, blood oxygen saturation is the amount of oxygen within a blood cell. The importance of this concept rests on the fact that higher levels of blood cell oxygen saturation will ultimately permit easier breathing and reduced shortness...
We may now extend this argument and consider in what circumstances the venous Po2 may fall below the critical level of 2.7 kPa (20 mmHg), which in normal blood corresponds to 32% saturation and about 6.4 ml/100 ml oxygen content. If the brain has a mean oxygen consumption of 46 ml/min...
The monitoring of oxygenation in the fetus or newborn demands a reliable way of estimating the oxygen content of blood. Although it is generally accepted that Pao2 monitoring is the gold standard surrogate of tissue oxygenation in preterm infants, there is no clinical evidence to date to support...

Alternatively, the high flow rate of THRIVE at 70L/minute may also mean additional smoke evacuation via suction is redundant. In addition to removing laser smog, the high flow rate may also provide continuous positive pressure to reduce atelectasis and shunting of deoxygenated blood through the ...
The key advantage of vis- OCT is that the 3D imaging capability allows one to recover optical spectra specifically from blood vessels and eliminate the confounding signal from other retinal layers25–27. We first validated the blood flow and sO2 measurements both in vitro and in vivo. Then, ...
blood vessels. Studies investigating the point spread function of GE BOLD responses at 7 T have shown that it spreads beyond the millimeter range, with an upper limit of approximately 2 mm15,16. More recently though, it has been argued that these estimates fail to account for the spread...
Commonly performed during an incremental test to exhaustion, maximal oxygen uptake (V̇O2max) assessment has become a recurring practice in clinical and experimental settings. To validate the test, several criteria were proposed. In this context, the p
Oxygen Plasma In subject area: Physics and Astronomy Oxygen plasma is defined as a widely used method for modifying materials, particularly nanopores, by increasing the OH group density on the surface. This modification allows for enhancing hydrophilicity and enabling specific reactions, although it aff...
Pentanoic, hexanoic and heptanoic acids were not produced by any strain in any atmosphere. Acetic acid (C2) was very abundant (>10 mM: upper detection limit) produced by all strains in aerobic blood culture vials supplemented with the 3 antioxidant molecules and incubated in anaerobiosis. A ...
