The telly star, 42, said he “nearly died” from a mystery double chest infection and thought: “This is it.”
Speaking from his hospital bed, he said he had a “massive needle jammed in my chest” like a scene from classic film Pulp Fiction.
Richard fell ill on a flight from Los Angeles, where he lives, earlier this month. He was taken to Lewisham Hospital in south London and put in a medically induced coma.
The former Blue Peter host joked he had overslept for six days. In a string of emotional tweets, he said: “So I did 6 days strght in a coma. Been here another 4 since.
“It’s an yet unidentified double chest infection. I nearly died.
“At one point, as I was run down a hallway to ICU at midnight, with a massive needle jammed in my chest (bit like Pulp Fiction) I thought, this is it. How’s this going to affect my kids’ lives?
“Who’s going to sit my poor dad down and say: ‘I’m sorry, we did everything we could.’ “But then I didn’t die. And I didn’t die because I’m on the NHS. #VivaTheNHS.”
He said he would see the NHS for its 100th birthday in 30 years’ time and joked he would probably have pneumonia by then.
“Mum, can you pass me my walking frame?” Is a phrase I never expected to utter.

“Within 90 minutes they had placed me into a life-saving six day coma”
Doctors have not yet diagnosed the cause of the illness, but Bacon praised the care he received. He said: “This is how good Lewisham Hospital is.
“I walked in off the street simply complaining of being short of breath. Within 90 minutes they had placed me into a life-saving six day coma. #VivaTheNHS.”
He also heaped praise on the nursing staff, saying: “Low on energy but I love and admire all the team.”
Comedian David Baddiel wrote: “Very much hope this is actually you tweeting this. In which case: welcome back.”
Richard replied: “I am alive. Or in Lewisham. Or somewhere between the two.” BBC Sport presenter Gary Lineker asked: “Have you overslept?” Richard said: “Yes. For 6 days straight.”
Meanwhile Love Island presenter Caroline Flack told him she was “so glad you’re OK”.
Richard, who also used to host a daily afternoon show for Radio Five Live, revealed he is having to use a walking frame as he recovers.
He added on Twitter: “‘Mum, can you pass me my walking frame?’ Is a phrase I never expected to utter.”
A fan replied: “I bet her hearing that is music to her ears after what happened to you get well soon.” Others wished him a speedy recovery
