Abstract

A bedside test is described which compares the patients cerebral arterio-venous oxygen difference with a predicted norm at various levels of arterial CO2 tension. In patients in coma depasse this difference is reduced and is unresponsive to variations in arterial carbon dioxide tension. The test also confirms lack of respiratory efforts in the presence of adequate carbon dioxide tension.

摘要

本文描述了一种床边测试，该测试可将患者的脑动静脉氧分压差与不同动脉二氧化碳分压水平下的预测正常值进行比较。在深度昏迷患者中，这种差异会减小，并且对动脉二氧化碳分压的变化无反应。该测试还可在存在足够二氧化碳分压的情况下确认呼吸努力的缺乏。
