Answer

The facemask design has evolved from black rubber to a transparent plastic cone.

Question: What are the advantages of the new design?

Answer: The transparent design has four advantages:

• Patient comfort (many patients disliked the black rubber masks)
• Assessing patient colour (hypoxia and cyanosis)
• Condensation on the inside of the mask, as the patient exhales, acts as a crude monitor of respiration
• To visualize any regurgitation, vomit or secretions from mouth or nose
