Could consuming somethin really cold like ice help to stop or prevent an asthma attack?

Not really. If you are having symptoms due to an asthma flare up, the best strategy would be to use a rescue inhaler/nebulization treatment such as albuterol for quick relief of symptoms. If you continue to have frequent symptoms that recur more than 2 times per week or have frequent night-time symptoms, then you may also require a daily controller medication such as inhaled steroids as well. Talk to your doc.
