Table 5 Monthly median values of facial frostbite time and facial frostbite time deficit

From: Environmental conditions at the South Col of Mount Everest and their impact on hypoxia and hypothermia experienced by mountaineers

Month	Median FFT	Delta FFT	Median FFTD	Delta FFTD
Month	(min)	(min)	(min)	(min)
May	19.3^a	3.7^a	7.2^a	5.5^a
June	59.4	34.5	7.5	4.1
July	77.2	41.8	14.5	infinity
August	72.2	22.4	8	11.9
September	24.5	13.2	9.7	6.8
October	5.9	5.7	8.9	2.5
November	6.1	5.9	7.5	7.3
December	9.7^a	4.7^a	5.5^a	0.4^a

Measured at the South Col during 2008. Also shown are the differences between the third and first quartile values for facial frostbite time (Delta FFT) and facial frostbite time deficit (Delta FFTD). ^aValues for which a full month's worth of data was unavailable.
