Myocardial 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 کاملUrinary oxygen tension: a clinical window on the health of the renal medulla?
We describe the determinants of urinary oxygen tension (Po2) and the potential for use of urinary PO2 as a "physiological biomarker" of the risk of acute kidney injury (AKI) in hospital settings. We also identify knowledge gaps required for clinical translation of bedside monitoring of urinary PO2. Hypoxia in the renal medulla is a hallmark of AKI of diverse etiology. Urine in the collecting du...
متن کاملMyocardial Tension and Oxygen Uptake.
• Since the report of Evans and Matsuoka ' a half century ago, it has been known that myocardial oxygen uptake increases in approximately a linear fashion with mean arterial pressure, but is affected only slightly by increases in cardiac output.' This paradox, that "pressure work" is much more costly than "volume work," complicated the analysis of the energetics of myocardial contraction. A con...
متن کاملIs coronary sinus blood oxygen tension behavior determined by myocardial oxygen tension variation during cardiac reperfusion?
The relationship between coronary sinus blood oxygen tension (CSPO2) and myocardial oxygen tension (MPO2) variations during cardiac ischemia and reperfusion was studied in anesthetized open-chest dogs. Oxygen tension was measured by a polarographic method. Ischemia resulted in a slightly decreased CSPO2 and a more pronounced reduction of MPO2. After reperfusion the CSPO2 rose rapidly and transi...
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...
