在过去的著述中，我们知道，由于乳酸碳酸氢盐的缓冲作用，超出乳酸阈值（LT）以外的动脉乳酸浓度[La－]的增长伴随着几乎等量的碳酸氢盐的减少。的减少伴随着有CO2呼出量多于有氧CO2生成量的情况。在呼出气体中有过剩CO2出现时的Vo2可由曲线的斜率分析检测，这种斜率分析可找
In the past, we know that due to the buffering effect of lactate bicarbonate, the increase of arterial lactate concentration [La-] beyond the lactate threshold (LT) is accompanied by an almost equal decrease of bicarbonate. The reduction is accompanied by more CO2 exhaled than aerobic CO2 production. Vo2 in the presence of excess CO2 in exhaled gas can be detected by the slope analysis of the curve, which can be found
