CPR can save lives, if it is done properly. However, many people don't know how to perform CPR (cardiopulmonary resuscitation) properly and even if you do, it can be dangerous for you. If there has been a car accident or other catastrophe and someone needs CPR but they have blood on their mouth or face, in this day in age, you need to be protected against diseases yourself. Microshields are the best way to keep from accidental contamination from occurring. A CPR microshield covers the mouth of the victim and has a valve for air to pass from the giver to the receiver. The valve only opens when the rescuer breathes out and closes when the rescuer finishes giving the breath. The masks even have a breathing tube that ensures an open airway.

These shields are important for everyone to have so they even have holders with a keychain attachment so you always know where your shields are in an emergency. You can even get them with a pair of high risk latex gloves for further protection.
