After a sleep study, which equipment is most commonly soaked and air-dried before reuse?

• A. Snap electrodes
• B. Snore microphone
• C. CPAP mask
• D. Body position sensor

Answer: (C)

Cleaning and disinfecting reusable PSG gear between patients is the main idea here. The CPAP mask is the item most commonly soaked and air-dried because it sits directly on the face for many hours and has cushions and silicone/foam components that can trap oils, skin cells, and microbes. Soaking in an approved cleaning/disinfection solution helps remove residue and kill microbes more effectively than a quick wipe, and air-drying completely prevents moisture buildup that could promote mold or degrade materials. After drying, the mask is ready to be inspected for wear and reassembled for safe reuse. The other items aren’t soaked for reuse because they’re either not designed for immersion (electronics like the snore microphone and position sensors) or are typically single-use or cleaned by wiping or replacement (snap electrodes).
