One report evaluated the effect with 60 mg of pseudoephedrine on individuals in a hyperbaric chamber at 1 atmosphere (simulated scuba dive to 66 feet of sea water). Pseudoephedrine and depth (stimulated) were found to have significant but opposite effects on heart rate, although these effects were unlikely to be clinically significant during diving.
