Using a barrier device for rescue breaths is a highly effective way to minimize the risk of disease transmission during CPR. These devices, such as pocket masks or bag-valve masks, create a physical barrier between the rescuer and the patient, reducing the likelihood of contact with saliva or other bodily fluids. This protective measure is particularly important in emergency situations where there may be uncertainty about the patient's health status, including the presence of infectious diseases.

While wearing gloves is beneficial for protecting both the rescuer and the victim, it's not always practical, especially in out-of-hospital settings where gloves may not be readily available. Performing CPR only on adults does not address the concern of disease transmission, as it ignores the need for proper precautions regardless of the victim's age. Washing hands after the procedure is good hygiene practice but does not prevent transmission during the actual event of providing CPR, when exposure might occur. Therefore, using a barrier device directly addresses the immediate need to protect against potential disease spread while delivering life-saving breaths.
