Why the study?
Does diving simulation alter pulmonary circulation hemodynamics in healthy volunteers?
Comparison
Resting state vs diving simulation vs after apnea
Design
Physiological study
Key result
Diving simulation by submerging the face in cold water decreased pulmonary vascular tone with a latent period of 0.6 to 10 s, which was faster than the 6 to 30 s latent period for ABP increase.

DCI reduction during face immersion may reflect peripheral vasodilation; hypothesis-generating for diving reflex physiology, needs validation before clinical relevance.

Does diving simulation alter pulmonary circulation hemodynamics in healthy volunteers?
The diving reflex induces a rapid, reflex-mediated decrease in pulmonary vascular tone that occurs independently of changes in systemic arterial blood pressure.
Podyacheva et al. (2020) reported an observational. Diving simulation (submerging face in cold water) vs. Resting state was evaluated on Hemodynamics of pulmonary circulation (dicrotic index, diastolic index, arterial blood pressure). Diving simulation by submerging the face in cold water decreased pulmonary vascular tone with a latent period of 0.6 to 10 s, which was faster than the 6 to 30 s latent period for ABP increase.
