Swansea head coach Guidolin resumed media duties on Thursday after spending five nights in a London hospital with a chest infection.
But the 60-year-old Italian, who said he experienced breathing difficulties after the 2-1 defeat at Tottenham Hotspur 11 days ago, has been told by doctors not to attend Swansea's Premier League trip to the south coast.
"My future is here because I have a contract for this season," said Guidolin, who suggested that the pressure of keeping Swansea in the top flight had contributed to his hospitalisation.
"The most important thing is to save the team and keep the possibility to play in the Premier League next year.
"I am happy to be here and there is the possibility to stay here a long time, but right now it is not important."
Guidolin joined Swansea in January after first-team coach Alan Curtis had spent nearly six weeks in charge after Garry Monk's departure.
He signed a contract until the end of the season with an option for another year.
But Guidolin spoke about the stressful nature of management after leaving Serie A club Udinese in May 2014, telling Italian newspaper La Gazzetta dello Sport that 'stress can help you but it can also hurt you'.
And, speaking after missing the victories over Arsenal and Norwich City which have boosted Swansea's survival battle, Guidolin said he finds it impossible to switch off from football.
"In the last two months my life has changed a lot," Guidolin said.
"There has been a new style, with my life, my food, my job, the language, the weather.
"I gave 100 per cent to do my job in the best way and to save the team.
"After I spoke to the chairman (Huw Jenkins), I felt a responsibility to save the team as I usually do.
"But after 50 days, my body said 'stop, Francesco.'
"I always give 100 per cent. I think about football, about my job 24 hours a day.
"This is not a good idea because sometimes I have to relax.
"But that is not my attitude, not my way of life.
"It's not easy for me to change because I'm not young, but I must try."
Guidolin was discharged from hospital on Monday and reunited with the Swansea players at the training ground on Wednesday.
But he did not take training and, although he will miss the Bournemouth game, he plans to be back for Aston Villa's visit to the Liberty Stadium next weekend.
"I need some more days of rest," said Guidolin.
"I've finished with antibiotics, but it's better for me to relax a bit more.
"For the match against Aston Villa, I hope to be back.
"What's important is the table now, the two victories against Arsenal and Norwich were very important."
