理解有困难

Lactate and ScvO2 normal: adequate oxygen delivery and cellular metabolism. In the case of adequate oxygen delivery and cellular metabolism, reflected as a normal lactate and ScvO2, routine postresuscitative care should be continued. Monitoring for deterioration in clinical status and therefore re-initiation of resuscitation should be implemented in those patients whose status remains tenuous. It is reasonable to avoid central venous catheter placement and ScvO2 measurement in patients with a normal lactate that have responded to fluid resuscitation.However, one will be unable to monitor a developing oxygen deficit. In that case, reassessing cardiac output periodically with bedside echocardiography may be useful with the plan of checking an ScvO2 should it start to fall.

乳酸和ScvO₂正常：充分的氧输送和细胞代谢。在氧输送和细胞代谢充分时（反映为正常乳酸和ScvO2），应继续常规复苏后治疗。应监测是否临床状态有恶化，从而在状态仍然不稳定的患者中再次复苏。对于液体复苏有效的乳酸正常患者，应避免中心静脉导管置入和 ScvO2测量。然而，（无中心静脉导管置入和 ScvO2测量），医护将无法监测正在发生的缺氧。在这种情况下，如果ScvO2开始下降，使用床旁超声心动图定期重新评估心输出量可能有助于检查ScvO2计划。

1.“医护将无法监测正在发生的缺氧”是不是指因为“无中心静脉导管置入和 ScvO2测量”？

2.“In that case”是不是指“oxygen deficit.”

3.should it start to fall是“如果ScvO2开始下降”？it指ScvO2？既然已经没有无中心静脉导管置入和 ScvO2测量，我怎么知道ScvO2开始下降？
