Normoxic 30% N2O alters baroreflex heart rate control in exercising men; leaves open its contribution to hyperbaric bradycardia.
Does a normoxic 30% nitrous oxide mixture alter baroreflex heart rate control in exercising men?
Mild inert-gas narcosis impairs baroreflex sensitivity and latency but does not fully account for the relative bradycardia seen during exercise in hyperbaric environments.
Östlund et al. (1999) studied this question.
