No baroreflex change with nitrous oxide in healthy volunteers; hypothesis-generating for effects in patients with cardiovascular disease.
Does 67% nitrous oxide inhalation alter spontaneous baroreflex gain and heart rate variability in healthy volunteers?
Inhalation of 67% nitrous oxide does not significantly affect cardiovagal reflex responses or spontaneous baroreflex gains in healthy volunteers.
Tanaka et al. (2004) studied this question.
