Table 1. Physiological variables at baseline and during OC.

Physiological data (n=6)
	Baseline	During OC
MABP	82.4±7	91.4±6.7*
Pa2 (mm Hg)	34.8±7	36.3±8.5
Pa2 (mm Hg)	85.8±7.4	310.6±84.1**
Blood pH	7.32±0.04	7.32±0.04

MABP, mean arterial blood pressure; OC, oxygen challenge.

Data are expressed as mean±s.d., ^*P<0.05 and ^**P<0.0001, Student's paired t-test.
