WitrynaObjectives: Impaired oxygen delivery due to reduced cerebral blood flow is the hallmark of delayed cerebral ischemia following subarachnoid hemorrhage. Since anemia reduces arterial oxygen content, it further threatens oxygen delivery increasing the risk of cerebral infarction. Thus, subarachnoid hemorrhage may constitute an important … WitrynaWhen the arterial oxygen content (CaO 2) and/or CO becomes impaired, DO 2 decreases, which is often accompanied by a parallel decrease in VO 2. The most frequently occurring scenarios are represented in Figure 1. In the early phase of decreasing DO 2, the circulation can compensate to some extent, and VO 2 remains … high tea in liverpool
