Face shields offer a simple, effective, and affordable means of protection against coming into contact with vomit, blood, or other substances when providing rescue breaths. If you don't have a face shield or cannot give rescue breaths, you can perform chest compressions only.
While packaging and design may vary, there are two main types of face shields:
Both types allow you to squeeze the nose and provide a barrier against substances. Face shields are available with a pouch and keyring, so they're always at hand. All BSI first-aid kits include some form of face shield.
Pocket masks are another type of face shield. They seal around the face and feature a one-way valve for ventilation. Air enters the patient's mouth and nose during rescue breaths.
Typically, pocket masks come in a plastic case. To remove the mask, push it until it pops up. An elastic band can be placed around the patient's head to secure the mask, and an air-filled sack around the mask ensures a proper seal. Pocket masks can also be used with oxygen if available.
Face shields are single-use only and should be disposed of safely after use.
