Fig. 5. The effect of increasing the duration of severe hypoxia on the input
pressure PIN required to maintain a resting cardiac output
of 1617 ml
min1 kg1. (A)
PIN recorded prior to
max1 and prior to
max2; (B) the
change in resting PIN between
max1 and
max2 (N=67
in each group). *Significant difference (P<0.05) identified using
repeated-measures ANOVA. One-way ANOVA did not reveal any significant
differences in the change in PIN between treatments.
