Procedure masks are effective in protecting patients from a healthcare worker's cough.

Procedure masks are designed to provide a barrier that helps prevent the transmission of respiratory droplets, which are a major mode of spreading infections, especially in a healthcare setting. When a healthcare worker coughs, these masks effectively reduce the dispersion of droplets into the air, thereby protecting patients from potential exposure to pathogens.

The design of procedure masks includes features that help to filter out larger respiratory droplets and may also reduce the inhalation of smaller particles, contributing to a safer environment for patients, especially those who may already be vulnerable. Hence, in contexts where healthcare workers might be coughing, the use of procedure masks plays a crucial role in infection control and patient safety.

Understanding this role emphasizes the importance of proper mask use as part of standard precautions in healthcare settings, ensuring both patient and worker safety during interactions.
