What are the consequences of failing to provide the requested instructions in a medical malpractice case?

On appeal, defendant argues for the first time that the requested instructions should have been given because there was evidence of unconsciousness "totally unrelated to [his] consumption of alcohol." This claim is forfeited. (See generally People v. Partida (2005) 37 Cal.4th 428, 435, 35 Cal.Rptr.3d 644, 122 P.3d 765 ["A party cannot argue the court erred in failing to conduct an analysis it was not asked to conduct."].) Even were the claim not forfeited, we would find it without merit.
