Low-Frequency Oscillations in Cardiac Sympathetic Neuronal Activity.

abstract：:Objective: Unexpectedly wide distribution (<10 to >90%) of hemoglobin oxygen saturation (sO2) within red cell concentrates (RCCs) has recently been observed. Causes of such variability are not yet completely explained whereas the roles of oxygen and oxidative lesions during the storage of RCCs are known. The objective...
