The most efficient oxygen unloading region around S = 0.38 could be revealed by the Adair analysis but not by analysis using the conventional Hill equation.doi:10.1016/0034-5687(94)90094-9Michiyori KobayashiKen-ichi IshigakiMichisuke Kobayashi...
Oxygen affinity to haemoglobin, as indicated by the p50 value, may be the most underestimated blood parameter in clinical practice. Moreover, potential influences of medication on cellular oxygen availability remains largely unknown. For instance, it has been shown that contrast media cause increased ...
expressed in ml min−1: D˙o2=CO×Cao2The oxygen content of arterial blood (Cao2) is described using the equation: Cao2=(k1×Hb×Sao2)+(k2×Pao2)Where Hb is the haemoglobin concentration (g litre−1), Sao2 is the arterial Hb oxygen saturation and Pao2 is arterial oxygen partial ...
It is generally accepted that the physiological limits of the Fick equation determinethe maximal rate at which O2 can be transported from the environment tothe mitochondria and utilised to support oxidative phosphorylation, termed themaximal oxygen uptake V˙O2max[5]. This is high...
Leghemoglobin is destroyed when the nodules lose their capacity for symbiotic nitrogen fixation. Leghemoglobin was isolated in 1939 from the nodules of horse beans. It was obtained in crystalline form in 1959 from soy nodules. Like other hemoproteins, leghemoglobin regulates the oxygen regime in ...
Taking the value of n in the Hill empirical equation: Open image in new window as a measure of the sigmoid character of the curve, this value should be lower than 2 for a splitting of hmoglobin into halves 5 .doi:10.1038/183827a0ROSSI-FANELLI, A...
An equation was derived to correct the errors made by pH on the saturation measurement of oxygenated blood.MackayA. RDooleyK. CWhyteR. KScandinavian Journal of Clinical & Laboratory Investigation
P50). Oxygenoxygen‐haemoglobin affinitySummary The effect a permanent change in the oxygen-haemoglobin affinity would have on the oxygen transport system is considered theoretically. The calculations were based on Hill's equation and its derivatives. It was demonstrated that in normoxia and at normal...
Total body haemoglobin was estimated by the alveolar equilibrium CO method and by dilution of 51Cr-tagged erythrocytes in 22 patients with a wide range of haemoglobin concentrations (51-190 g/l). The resulting regression equation: THBCO =47 + 0.81 X THbCr, where THn is expressed in grams,...
Slices from animals after exposure to piperonyl butoxide, metyropone or diazinon follow Warburg's equation (Longmuir et al., 1971). The mechanism postulated to explain these findings is that normally the transport of oxygen through tissue is facilitated by cytochrome P-450. When this latter ...
