Total body VO2 is maintained at a constant level by an interaction between mixed venous O2 saturation, the arterial O2-carrying capacity, and hemodynamics during exercise with acute and chronic hypoxia. 展开 DOI: 10.1152/jappl.1998.85.3.1092 年份: 1998 ...
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 ...
(A) Single-cell oxygen saturation imaging of RBCs that had been biochemically rejuvenated or sham treated. Rejuvenation robustly restores the unloading time constant of long-stored RBCs toward reference values. (B) Matched time courses of partial pressures of O2 (PO2) in arterial blood, kidney ...
The animals over the final 10-15 min of the insult became brady- cardic (heart rate less than 100) and hypotensive with mean arterial blood pressure below the limits of autoregulation for the newborn lamb. The animals were then returned to control ven- tilator settings and fractional ...
We investigated the effect of increasing hemoglobin- (Hb) O2 affinity on muscle maximal O2 uptake (VO2max) while muscle blood flow, [Hb], HbO2 saturation, and thus O2 delivery (muscle blood flow X arterial O2 content) to the working muscle were kept unchanged from control. VO2max was me...
A 36-year-old woman is found comatose at her home and is life-flighted to the nearest regional medical center.Blood gases reveal a normal PaO2 but a lower-thannormal arterial O2 saturation.Which of the following conditions is most consistent with the find ...
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 ...
Identify indication for oxygen therapy -oxygen tension and saturation level (a) Define blood flow. (b) Name two factors that influence blood flow. What is the relationship between hemoglobin and P_{O_2...
In healthy adult volunteers, measured oxygen saturation values (SpO2) were compared with arterially sampled oxygen saturation values (SaO2) during controlled hypoxemia. In vitro correlation and agreement with gas mixtures of tcPO2 (r = 0.999, bias 3.0 mm Hg, limits of agreement 6.6 to 4.9 mm ...
