Which protective option should be used when delivering rescue breaths to reduce exposure risk?

• A. Mouth-to-mouth only, with no barrier.
• B. Pocket mask or face shield.
• C. No protection is necessary.
• D. A wet towel placed over the mouth.

Answer: (B)

When giving rescue breaths, using a barrier device is essential to reduce exposure to potential pathogens. A pocket mask or face shield creates a physical barrier between your mouth and the patient’s airway and often includes a one-way valve, which helps prevent the patient's breath and fluids from reaching you while you ventilate. This makes it the most protective option for delivering breaths. Mouth-to-mouth with no barrier exposes you directly to droplets and secretions, a wet towel over the mouth does not provide a reliable seal or protection, and having no protection at all is unsafe.
