May indicate vagal enhancement during HBO in divers; leaves open clinical relevance and needs larger validation.
Does hyperbaric oxygen increase parasympathetic activity compared to hyperbaric air in professional divers?
Hyperbaric oxygen at 2.5 ATA significantly increases parasympathetic tone compared to hyperbaric air in professional divers.
Lund et al. (2000) studied this question.
