Why the study?
Does hyperbaric (4 atm) exposure alter cardiovascular hemodynamics, autonomic function, and biochemical markers in healthy professional divers?
Population
18 healthy volunteers who were professional divers of similar age and experience
Comparison
Hyperbaric exposure in a hyperbaric chamber vs Baseline (measurements taken before exposure)
Design
Cohort
Follow-up
Immediately after exposure (within almost one hour)

Hyperbaric changes in healthy divers should not alter practice; leaves open effects in patients or on outcomes.
Does hyperbaric (4 atm) exposure alter cardiovascular hemodynamics, autonomic function, and biochemical markers in healthy professional divers?
Hyperbaric exposure at 4 atm significantly alters cardiovascular hemodynamics and autonomic balance, increasing afterload and parasympathetic activity in healthy divers.
Kozakiewicz et al. (2018) studied this question.
