CPR breathing masks are vital emergency tools designed to provide safe and effective resuscitation during cardiac or respiratory arrest. Constructed from durable, transparent plastic, these masks ensure a tight seal over the patient’s mouth and nose, allowing for efficient delivery of rescue breaths. Equipped with a one-way valve, they prevent cross-contamination and protect rescuers from exposure to bodily fluids. The compact, portable design makes them easy to carry in first aid kits or emergency response bags. These masks are essential for both professional rescuers and laypersons, enabling life-saving interventions in critical situations by providing a barrier between the rescuer and patient while maintaining effective ventilation.
