If you find yourself trapped beneath a mountain of snow, it is important that you create a space that will allow you to breathe before the snow settles and becomes a solid mass. Most avalanche deaths occur from suffocation. By creating a small space you will be able to breathe and figure out if you are injured and what your next steps should be. The ability to breathe will allow you to remain calm and come up with some sort of survival plan.
By wearing an avalanche transceiver and knowing how to properly use them will greatly increase your chances of being rescued. As long as the other members of your party know your location and can relay that information to rescuers, you may have a greater chance of survival. It is important to note that most people can only survive buried under snow for approximately 30 minutes, this makes your rescue a race against time, but by giving rescue workers accurate details as to your location your chances are much better as to being found in time.
Along with the avalanche transceiver it is also recommended that you have some type of snow shovel packed in your gear. This will allow for you to dig out a larger space around you to increase your available air. If you are able to dig enough space around you, it may be possible for you to keep shoveling and possibly work yourself out of the snow. This process will use a lot of energy, so it is important that you keep that in mind before attempting to dig yourself out.
