Hyperoxic hypercapnia effects on breathing variability in volunteers should not change practice; leaves open chemoreflex mechanisms for prospective study.
Does hyperoxic hypercapnia alter the variational activity of breathing in volunteers compared to air?
Hyperoxic hypercapnia increases the correlated behavior of volume components in breathing, accompanied by low-frequency oscillations consistent with central chemoreceptor activation.
Jubran et al. (1997) studied this question.
