In vivo photoacoustic tomography of myoglobin oxygen saturation.
Myoglobin is an essential oxygen-binding hemoprotein in skeletal and cardiac muscles that buffers intracellular oxygen (O2) concentration in response to hypoxia or elevated muscle activities. We present a method that uses photoacoustic computed tomography to measure the distribution of myoglobin in tissue and the oxygen saturation of myoglobin (sO2-Mb ). From photoacoustic measurements of mice ...
متن کاملpulse oximeter oxygen saturation in prediction of arterial oxygen saturation in liver transplant candidates
results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...
متن کاملVirtual cooperativity in myoglobin oxygen saturation curve in skeletal muscle in vivo
BACKGROUND Myoglobin (Mb) is the simplest monomeric hemoprotein and its physicochemical properties including reversible oxygen (O2)binding in aqueous solution are well known. Unexpectedly, however, its physiological role in intact muscle has not yet been established in spite of the fact that the role of the more complex tetrameric hemoprotein, hemoglobin (Hb), in red cells is well established. ...
متن کاملMyocardial myoglobin oxygen tension.
COBURN, R. F., F. PLOEGMAKERS, P. GONDRIE, AND R. ABBOUD. Myocardial myoglobin oxygen tension. Am. J. Physiol. 224(4): 870-876. 1973.-We have applied our method of estimating mean myoglobin oxygen tension from measurements of carbon monoxide binding to myoglobin to the in vivo canine myocardium. Carbon monoxide binding to myoglobin was determined with measurements of 14C0 in myocardial biopsy s...
متن کاملValidity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
