Trainee-Shield makes CPR manikin training easier, faster, and more economical, and fits most training manikins. The short airway stem takes the guesswork out of correctly positioning the shield, while preventing it from falling off the manikin during chest compressions. The Trainee Shield can be used in combination with CPR Prompt face shield/lung bags to eliminate the need to change lung bags when sharing a manikin during class. FOR TRAINING ONLY. 20 shields/package. (TSHLD20)
