First it depends on whether you are asking for a fair division of the settlement between loss of consortium and her injury, or whether you are talking about dividing it as marital property in a divorce. If it is consortium that you are asking about, it depends on how severe her injury is, how it will affect her for the rest of her life, and how it has affected your life and how it will in the future. If you are asking how it should be divided in a divorce, that depends on a number of factors, such as what other marital property is being divided, any non marital property that you or she has, direct and indirect contributions to your acquiring marital property, your earnings capacity vs hers which relates to your relative abilities to acquire property in the future, how much of the settlement relates to your (the two of you) loss during the marriage, and how much relates to her future loss, such as future pain and suffering. There are probably more factors that I have not mentioned. If you have an attorney, you and your attorney should work on figuring it out.
