		_∆SO2_-vdbh (%)			_∆SO2_-vdrt (%)
		Max	Min	\(\bar{x}\) ± S	Max	Min	\(\bar{x}\) ± S

		F = 3.562, p = 0.06			F = 1.38, p = 0.243
B	NIO	5	0	1.975 ± 1.31	6	0	1.84 ± 1.53
	IO	3	0	0.40 ± 0.63	3	0	0.75 ± 1.73

Note: _∆SO2-vdbh: SpO2 variation during breath-holding; _∆SO2-vdrt: SpO2 variation during rest; NIO: not inhaling oxygen; IO: inhaling oxygen: S = standard deviation.
