In this study, LECOM 2nd-year medical student Matt Heffernan used three different gas combinations to acutely alter chemoreceptor control of forearm blood flow. He found that brief hyperoxia (100% oxygen inhalation) attenuated the forearm vasoconstrictor response to voluntary apnea in in both muscle (-16 ± 10 vs. -40 ± 12%, P = 0.023) and skin (-14 ± 6 vs. -24 ± 5%, P = 0.033). However, neither hypoxia nor hypercapnia had significant effects on cutaneous responses to apnea. This is the second published article by Heffernan and Muller in the past 10 months.
