Table 1. Physiologic Parameters during the Different Experimental Conditions

Values are presented as mean ± SD; n = number of participants. There were no values significantly different from the control condition (normo) other than the end-tidal carbon dioxide (ETco²) concentration.

Hypo = hypocapnia; BP^mean= mean arterial blood pressure; Sao²= peripheral oxygen saturation; N²O = nitrous oxide.
