在两个不同指导的组中研究了CO2吸入对主观状态、心率和血压的影响，并使用空气作为安慰剂。那些被告知吸入会产生愉快的放松状态的参与者报告了一个统计学上显著的变化，证实了当给予CO2时的变化，而空气并没有明显地改变主观状态。那些预期会有不愉快的紧张感的参与者在吸入CO2后确实表现出了一个不显著的变化，而安慰剂完全没有这种反应。CO2摄入后心率和舒张压显著下降。令人惊讶的是，参与者在呼吸空气时心率显著下降，最后，提出了一些理论推论，并强调了认知过程在CO2疗法临床应用中的作用。
The effects of CO2inhalation on subjective state, heart rate and blood pressure were studied in two differently instructed groups, with use of air for placebo. Participants who were told that inhalation would produce a state of pleasant relaxation reported a statistically significant, confirming change when administered CO2, whereas air was found not to after the subjective state appreciably.Those who had expected unpleasant feelings of tension did show a non-significant change in this respect after CO2inhalation and no such reaction at all to the placebo. Heart rate and diastolic blood pressure dropped significantly after CO2intake. Surprisingly, participants were subject to a significant decrease in heart rate upon inhalation of air when relaxation was expected.Finally, a number of theoretical inferences are made and the role of cognitive processes in the clinical use of CO2therapy is underscored.
