A resuscitator mouth shield assembly for protecting a caregiver from bodily fluids during CPR includes a resuscitation bag that has a hose extending toward a face cup. A coupler releasably engages the resuscitation bag and a panel is rotatably coupled to the coupler. The panel is spaced from the resuscitation bag when the coupler is positioned on the resuscitation bag. Moreover, the panel is positioned between a patient's face and a caregiver when the resuscitation bag is positioned on the user's face. In this way the panel inhibits bodily fluids that are expelled from the patient from contacting the caregiver.
