Key result
The diving response, which generally reduces heart rate by 15 to 40% in humans, acts as an oxygen-conserving defense mechanism that lengthens the time to the onset of serious hypoxic damage.

May inform apnea management in divers; leaves open therapeutic modulation pending prospective trials.
Diving bradycardia serves as an important physiological defense mechanism to conserve oxygen and delay hypoxic damage during apnoea and cold water immersion.
Alboni et al. (2011) conducted a review in Diving bradycardia. Diving response was evaluated. The diving response, which generally reduces heart rate by 15 to 40% in humans, acts as an oxygen-conserving defense mechanism that lengthens the time to the onset of serious hypoxic damage.
