A doctor has given warnings to viewers why it's not a good idea to hold a drowning person upside down during rescue.
NHS surgeron Dr Karan Rajan, who gained his fame on TikTok thanks to his 4.3million followers, recently debunked a video on sexually transmitted disease and explained that there's possibly "only one chance" that you could get chlamydia from sore throat.
Yesterday he shared his first-aid tips to fans when someone is drowning.
He responded to a video which a woman says: "Now I am CPR certified, I would never want this video to advocate for anything other than immediately starting CPR once you've pulled someone out of the water after they've downed…
"But why doesn't turning someone upside down?"
The medical expert grabs a kettle and fills it up with water while explaining: "When water hits the airway, it triggers something known as laryngospasm.
"The larynx constricts and seals off the airway so no water can get into the lung.
"This also means no more oxygen can get in either and it's the lack of oxygen that gets them.
"Tiny bit of water does enter the lung but it's absorbed by the bloodstream.
"If you hold someone upside down like a prized fish, you would be treating the wrong thing. The two things we need to focus here is circulation and oxygenation."
Viewers found the first-aid information useful and many who took the courses agreed with Dr Rajan.

One said: "Yup! We learned in lifeguarding that you do two breaths first for a drowning victim before CPR (if they're unresponsive with no heart beat) for this exact reason. Get that air!"
Another wrote: "Thank you for making this video! It is scary how social media platforms are spreading disinformation and doubt about the medical field."
"Never wonder that and never knew that, thank you doc!" a third added.
