CPR Pocket Masks & Rescue Breathing Barriers

A CPR pocket mask is a reusable or semi-reusable barrier device designed to fit over a patient's nose and mouth while a rescuer provides ventilations. Many models use a one-way valve or filter to help reduce direct contact with saliva, blood and other body fluids during rescue breathing.

Pocket Mask vs. CPR Face Shield

Pocket masks and face shields are both CPR breathing barriers, but they work differently.

• Pocket masks create a seal over the nose and mouth and usually use a one-way valve. Many models also include a filter, oxygen inlet or head strap.
• CPR face shields are thin, compact barriers placed over the patient's face. They are often intended for single use and are easy to carry in a first aid kit, wallet or keychain pouch.

Current American Heart Association guidance recognizes both pocket masks and face shields as acceptable barrier options for rescuers providing breaths, while noting that pocket-mask ventilation can provide more effective breaths than a face shield when a pocket mask is available.

What to Look for in a CPR Pocket Mask

• One-way valve: Helps separate the rescuer from the patient's exhaled air and fluids.
• Protective filter: Some models add filtration between the patient and rescuer.
• Adult or pediatric sizing: Choose a mask sized appropriately for the patient population.
• Oxygen inlet: Certain professional masks allow supplemental oxygen to be connected.
• Head strap: Available on some masks for additional stability during ventilation.
• Hard or soft case: A case can help protect the mask during transport and storage.

CPR Training Masks & Replacement Valves

Training masks, practice valves and replacement components allow CPR instructors to prepare equipment for repeated classroom use. Training-only components should not be confused with patient-use valves or filters, so always verify that the replacement part is intended for your specific mask and application.

Frequently Asked Questions

What is a CPR pocket mask used for?

A CPR pocket mask is used as a barrier while providing rescue breaths. It fits over the patient's nose and mouth and allows the rescuer to ventilate through a one-way valve or filtered mouthpiece.

Is a CPR pocket mask reusable?

Many pocket-mask bodies are reusable when cleaned and disinfected according to the manufacturer's instructions, while valves, filters or other components may be single-use or require periodic replacement. Check the instructions for the specific mask.

Are pocket masks available for children and infants?

Yes. Pediatric and infant masks are available, along with combination kits that include more than one mask size. Use equipment appropriately sized for the patient.

Can a pocket mask be used with supplemental oxygen?

Some professional pocket masks include an oxygen inlet that allows supplemental oxygen to be connected. Not every model has this feature, so check the individual product specifications.

What is the difference between a training valve and a rescue valve?

Training valves are intended for repeated classroom practice, while patient-use valves and filters are designed for actual rescue applications. Do not assume that a training component is appropriate for emergency use.
