Being blown into space isn't instantly lethal nor do people suddenly freeze over when exposed to space. This is a tv/movie trope which ignores basic physics.
This article from Scientific American has some interesting points
In reality, however, animal experiments and human accidents have shown that people can likely survive exposure to vacuum conditions for at least a couple of minutes. Not that you would remain conscious long enough to rescue yourself, but if your predicament was accidental, there could be time for fellow crew members to rescue and repressurize you with few ill effects.
and this from a different source
After losing consciousness, you’ll probably last a couple of minutes maximum before you die. Of course, there’s all that nasty UV from the Sun which is going to give you horrific sunburn. UV and other high energy photons (X-rays and gamma radiation) would also damage the heck out of your DNA, leading to mutations that would likely cause cancer (if you survived). It’s also typically extremely cold, but you wouldn’t instantly freeze as the vacuum would cause heat to transfer away from the body very slowly.
In sum- you’d swell up, burn, mutate, pass out and your lungs might explode. Lovely. But don’t worry, if you’re ever in this sticky situation, you’ve probably got a solid minute or two to be rescued before you die, so chin up.
Of course these are the scientific answers, in the MCU the characters have plot armor and other explanations can always apply.
