The effect of lactate infusion on pCO2 and respiration rate was studied in two differently instructed groups of healthy volunteers in a double-blind, placebo-controlled, cross-over study. Both groups showed a significant decrease in alveolar pCO2 after lactate but not after placebo. This was accompanied by an increase in respiration rate in those subjects who had expected to become anxious and by a decrease in respiration rate in those who had expected to experience pleasant excitement.
在一项双盲、安慰剂对照、交叉研究中，对两组接受不同指导的健康志愿者进行了乳酸输注对pCO2和呼吸频率影响的研究。两组在输注乳酸后肺泡pCO2均显著下降，而输注安慰剂后则无此现象。这伴随着预期会变得焦虑的受试者呼吸频率增加，以及预期会体验到愉悦兴奋的受试者呼吸频率降低。
