Table 1.

Physiological parameters before (prechallenge) and during (challenge) oxygen challenge

	Prechallenge	Challenge
Body temperature (°C)	36.9±0.2	36.8±0.2
Mean arterial blood pressure (mm Hg)	86±9	97±6^*
Heart rate (b.p.m.)	381±24	379±23
Blood pH	7.36±0.02	7.34±0.04
PaO₂ (mm Hg)	95.9±11.7	331.6±91.7^*
PaCO₂ (mm Hg)	37.1±5.5	40.2±1.6

Data are expressed as means±s.d. (series 1, n=5).

Student’s paired t-test revealed a significant increase in mean arterial blood pressure (P<0.005) and PaO₂ (P<0.05) during OC.
