Central venous O2 saturation difference as pronostic marker of diastolic dysfunction and weaning failureManuel Martínez MedinaMarlene Cendejas GutiérrezOlga Rosa Brito Zurita
Further reductions in already low levels of mixed venous O2 saturation were responsible for the maintenance of VO2 on arrival and after 21 days at 4,300 m in propranolol-treated subjects. Despite similar workloads and VO2, propranolol-treated subjects exercised at greater perceived intensity than ...
Value of central or mixed venous O2 saturation in guiding treatment in the intensive care unitGroeneveld, A B J
Indeed, a left-shifted O2-saturation curve could still release the amount of O2 instructed by respiration by attaining a lower PO2 at the venous end, provided there is sufficient time for gas equilibration. To measure O2-unloading from RBCs, we developed single-cell oxygen saturation imaging. ...
Septic shock was associated with low FAR that was not affected by the FBF decrease, indicating that in this condition, hemodynamics could be influenced by skeletal muscle resistance. 展开 关键词: cytochrome aa3 endotoxemia cerebral arterial and venous oxygen saturation difference near-infrared ...
VO2max was 11.8 +/- 1.0 ml.min-1.100 g-1 when perfused with the normal blood (control) and was reduced by 17% to 9.8 +/- 0.7 ml.min-1.100 g-1 when perfused with the low-P50 blood (P less than 0.01). Mean muscle effluent venous PO2 was also significantly less (26 +/- 3 ...
The surgical procedures are tolerated nicely and an indwelling sagittal sinus catheter for sampling cerebral venous drainage can be reliably placed. The animals were very stable after the asphyxial insult from the cardiopulmonary stand- point allowing for repetitive assessments of the cerebral circula- ...
The heart rate, arterial blood pressure, arterial and brain venous pH, PCO2, PO2, O2 saturation, and Hb values were measured immediately before the microsphere injection. Blood pH, PCO2, and PO2 were measured with a blood gas analyzer (model ABL50; Radiometer, Copenhagen, Denmark), and ...
When pH decreases, O_2 saturation of hemoglobin decreases - what is this effect called? Low blood hemoglobin level: a) Increases breathing b) Decreases breathing Will the pH of the blood increase or decrease as a result of hype...
