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 کاملArterial oxygen tension increase 2-3 h after hyperbaric oxygen therapy: a prospective observational study.
BACKGROUND Inhalation of hyperbaric oxygen (HBO) has been reported to decrease arterial oxygen tension (PaO(2)) in the early period after exposure. The current investigation aimed at evaluating whether and to what extent arterial blood gases were affected in mechanically ventilated intensive care patients within 6 h after HBO treatment. METHODS Arterial blood gases were measured in 11 ventila...
متن کاملHigh oxygen tension constricts epineurial arterioles of the rat sciatic nerve via reactive oxygen species.
Microcirculation of the sheath of the rat sciatic nerve fiber was investigated by using an intravital microscope, and changes in the diameter of the epineurial arterioles in response to highly oxygenated Krebs-bicarbonate solution were evaluated. Superfusion of low-oxygen (0%) Krebs-bicarbonate solution (LKS) onto rat sciatic nerves did not affect changes in the diameter of the arterioles. Nife...
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 کاملHigh flow oxygen therapy for pneumatosis coli.
Symptomatic and radiological resolution of pneumatosis coli was achieved by intermittent high flow oxygen therapy in five patients. In each case the extent of the disease was defined by colonoscopy and contrast radiography before treatment. Despite the confirmation of pneumocyst resolution, recurrence of colonic gas cysts was noted in two patients at six months and one year after treatment. Bac...
