Being in space unprotected for short periods of time isn't really that bad, especially if you have a breathing mask.
"Some
degree of consciousness will probably be retained for 9 to 11 seconds
(see chapter 2 under Hypoxia). In rapid sequence thereafter, paralysis
will be followed by generalized convulsions and paralysis once again.
During this time, water vapor will form rapidly in the soft tissues and
somewhat less rapidly in the venous blood. This evolution of water
vapor will cause marked swelling of the body to perhaps twice its
normal volume unless it is restrained by a pressure suit. (It has been
demonstrated that a properly fitted elastic garment can entirely
prevent ebullism at pressures as low as 15 mm Hg absolute [Webb, 1969,
1970].) Heart rate may rise initially, but will fall rapidly
thereafter. Arterial blood pressure will also fall over a period of 30
to 60 seconds, while venous pressure rises due to distention of the
venous system by gas and vapor. Venous pressure will meet or exceed
arterial pressure within one minute. There will be virtually no
effective circulation of blood. After an initial rush of gas from the
lungs during decompression, gas and water vapor will continue to flow
outward through the airways. This continual evaporation of water will
cool the mouth and nose to near-freezing temperatures; the remainder of
the body will also become cooled, but more slowly.
"Cook and
Bancroft (1966) reported occasional deaths of animals due to
fibrillation of the heart during the first minute of exposure to near
vacuum conditions. Ordinarily, however, survival was the rule if
recompression occurred within about 90 seconds. ... Once heart action
ceased, death was inevitable, despite attempts at resuscitation....
[on
recompression] "Breathing usually began spontaneously... Neurological
problems, including blindness and other defects in vision, were common
after exposures (see problems due to evolved gas), but usually
disappeared fairly rapidly.
"It
is very unlikely that a human suddenly exposed to a vacuum would have
more than 5 to 10 seconds to help himself. If immediate help is at
hand, although one's appearance and condition will be grave, it is
reasonable to assume that recompression to a tolerable pressure (200 mm
Hg, 3.8 psia) within 60 to 90 seconds could result in survival, and
possibly in rather rapid recovery."
