A pocket mask, or CPR mask, is a portable device used to deliver rescue breaths safely during cardiac or respiratory arrest. It prevents direct contact with the patient's mouth, reducing infection risk while ensuring effective ventilation. Compact and easy to carry, it's essential in emergency medical situations.
