Peter Roy Alfred, Jr., Louisiana prisoner # 315023, moves for leave to proceed in forma pauperis (IFP) on appeal following the district court’s denial of his IFP motion and certification that his appeal was not taken in good faith. He seeks to appeal the dismissal of his 42 U.S.C. § 1983 *584 suit alleging that the defendants, inter alia, violated his Eighth Amendment rights by denying him a continuous positive airway pressure machine (CPAP). Alfred’s IFP motion challenging the certification decision “must be directed solely to the trial court’s reasons for the certification decision.” Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir. 1997). Although this court previously imposed a 28 U.S.C. § 1915(g) bar upon Alfred in rejecting a similar case against different defendants, see Alfred v. Forcht Wade Corr. Ctr., 354 Fed.Appx. 58, 59-60 (5th Cir. 2009), the instant appeal was filed before the bar was imposed.

Because Alfred has not challenged the district court’s dismissal of his claims against the Corrections Corporation of America, Winn Correctional Center, Tim Wilkinson, Angie Martin, and Tim Morgan, he has abandoned his claims against these defendants. See Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Further, he challenges only the district court’s dismissal of his Eighth Amendment claims against the remaining defendants; accordingly, he has abandoned all but those Eighth Amendment claims. See Brinkmann, 813 F.2d at 748.

The record shows that Alfred received medical attention for his sleep apnea following his transfer to Winn Correctional Center and that the sleep apnea never posed a serious risk to Alfred’s health. See Norton v. Dimazana, 122 F.3d 286, 291-92 (5th Cir. 1997). Alfred has been receiving CPAP treatments since May 2008.

Alfred’s appeal is without arguable merit and is frivolous. See Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983). He continues to be barred from proceeding IFP in any civil action or appeal filed while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See § 1915(g). He should review any pending appeals and withdraw any that are frivolous.

Alfred’s motion to proceed IFP is DENIED, and his appeal is DISMISSED as frivolous pursuant to 5th Cir. R. 42.2.
