Peripheral saturation, blood glucose, heart rate, and mean arterial blood pressure during pool apnea.

	Rest	End BH	After BH
Mean arterial pressure/mmHg	103 ± 11	148 ± 15*	104 ± 31
Heart Rate/beats min–1	86 ± 14	46 ± 10*	64 ± 9*
Peripheral Saturation/%	99.6 ± 0.5	58.5 ± 5.5*	N/A
Blood glucose mmol/l	5.8 ± 0.2	6.2 ± 0.2 #	N/A

Values are means ± SD; *P < 0.001 vs. rest. #P = 0.009 vs. rest. BH = breath hold.
