A doctor explains why you should never turn a drowning victim upside down.
NHS surgeon and TikTok star Dr Karan Rajan used a kettle to simulate the dangers of “catching someone like a prized fish” during first aid.
He was responding to a video in which a woman said: “Now that I’m CPR certified, I would never want this video to advocate for anything other than starting CPR immediately, when you’re trying to get someone out of the water.” After that take it out from the water.
“But why turning someone upside down doesn’t work?”
Dr Rajan, who has 4.4 million TikTok followers, explained that doing so actually shuts off the oxygen supply and used a kettle for the performance.
In the video shared on Instagram, he said: “When water hits the airway, whether you’re conscious or unconscious, it triggers something known as a laryngospasm.
“The larynx in the upper airway contracts and closes off the airway so that no more water can get into the lungs.
“But it also means that no more oxygen can get into both and it’s the lack of oxygen that gets them.
“Only a tiny bit of water ends up in the lungs but that gets absorbed by the bloodstream.
“If you catch someone upside down like a prized fish, you will be doing it wrong.
“The two things we need to focus on here are circulation and oxygenation.”
A bystander asked if you were trying to open a closed kettle lid while performing CPR.
Dr Rajan replied: “No, you are trying to compress the heart to maintain blood flow to vital organs.”
His followers immediately praised him for another educational clip.
One wrote: “Thank you for making this video! It’s scary how social media platforms are spreading misinformation and doubts about the medical field.”
Another commented: “You are the man. Love those educational videos.”
Dr Rajan has previously explained why you shouldn’t sleep in front of you, what really happens when someone is cremated, and why amputated feet keep washing up on beaches – still with their trainers.
