• "CPR" is a stomping melodrama about the dizzying rush of new love, using the metaphor of a medical emergency to capture the overwhelming and sometimes dangerous feelings that come with falling for someone hook, line and sinker.
• Wet Leg's Rhian Teasdale wrote the song amid the uncertainty of a new relationship. She wonders, "Is this love or suicide?" over a seismic bassline. Teasdale ultimately makes her choice clear with the urgent plea:
  
  Put your mouth to mine and give me CPR
• Teasdale co-wrote "CPR" with bandmate Ellis Durand for Wet Leg's second album, Moisturizer. It was the first love song they penned for the record, which is packed with tracks exploring love's highs and fears. Speaking to BBC Radio 1's Jack Saunders, Teasdale explained:
  
  "I think I was accessing the fear around, like, 'Oh no, I'm about to really fall for this person.' It was kind of a springboard for all the other love songs on the album that would follow."
• The self-directed music video matches the song's spontaneous energy, showing the band cruising through lush, sunlit landscapes in one continuous take.
• Producer Dan Carey, who's also worked with Foals and Fontaines D.C., has been Wet Leg's go-to since their debut single. He's known for capturing their playful, energetic, and slightly chaotic sound without over-polishing it.
