A 23-year-old man with recent community-acquired pneumonia is admitted to the hospital for worsening respiratory status. He continues to deteriorate rapidly, requiring emergent intubation due to decreasing oxygen saturation. Chest radiograph is shown below. Despite maximal ventilatory support, oxygenation continues to decrease to below 50 mmHg, and venovenous extracorporeal membrane oxygenation (ECMO) is implemented shortly thereafter. After initiation of flow through the ECMO circuit, arterial blood gas results show: pH 7.19, partial arterial carbon dioxide pressure 67 mm Hg, and partial arterial oxygen pressure 72 mm Hg.The most effective method of increasing carbon dioxide elimination is to increase which of the following parameters?E. Ventilatory respiratory rate一名最近患有社區獲得性肺炎的23歲男子，因呼吸狀況惡化而入院。 他的病情繼續迅速惡化，由於氧飽和度降低需要進行緊急插管。 胸部X光片如下所示。儘管有最大的通氣支持，但氧合持續降低至50 mmHg以下，此後不久便實施了靜脈靜脈體外膜肺氧合（VV-ECMO）。 在ECMO轉流開始後，動脈血氣結果顯示：pH 7.19，動脈二氧化碳分壓67 mmHg和動脈氧氣分壓72 mmHg。
