It was something no man needs to hear.
Guisborough man, Rory Spence, 45, left with a sense of "absolute fear" when he was his wife, Lisa, a mother of three, took seriously ill.
Mrs. Spence, who works in insurance sales, was admitted to the hospital after complaining about coughing and breathing difficulties and nobody could figure out what was wrong.
But things quickly got worse when doctors pulled Mr. Spence aside and said, "This is really serious now, do we have permission to put her in a coma?"
& # 39; I knew things were getting pretty serious back then & # 39;
She had initially thought her ailments were flu symptoms, but a few trips to the doctors could not determine what the problem was.
Then one day, about a year ago, things got worse.
"I went to bed, she woke me up in the early morning and said she couldn't breathe," Mr. Spence told Teesside Live.
"Her heartbeat was absolutely crazy.
& # 39; The following, you know, she hurriedly ended up in the course.
"I knew it was getting pretty serious back then.
"Then they decided to move her to the high dependency unit.
& # 39; She spent the day and night there. & # 39;
When her condition did not improve, Mr. Spence received the devastating news that his wife had to be put in a coma.
Fortunately, after five days in the coma and another four at James Cook University Hospital, the 44-year-old has undergone a full recovery.
It was concluded that she had an undiagnosed asthma that was exacerbated by an infection.
Mr. Spence added: "Without the team of specialized consultants, doctors, nurses and other support staff, she simply would not be here.
"The NHS sometimes gets a stick behind it, the government, not the employees' fault, they are just professionals and go beyond their duty.
"I would like to make more people aware of how asthma can easily make a fit and healthy person seriously ill. I also want to make people aware of the fantastic work that NHS staff do."
& # 39; Fantastic work & # 39; from the NHS
To thank hospital staff and also raise funds for Asthma UK, Mr. Spence, a production manager, plans to fight the pain caused by arthritis in his hips and run the London Marathon later this month.
The money will be shared equally between the charity and the James Cook hospital, you can find more information on his fundraising page.
