The air ambulance was called to a north Norfolk holiday park after a man was taken ill in the swimming pool.
The incident happened at about 2pm today at Woodland Holiday Park in Trimingham.
Andrew Hird, the park's general manager, said: 'A man was taken ill at the park while he was in the swimming pool.
'My team on site administered immediate CPR and by the time he left the park he was breathing. The paramedics arrived in record time.'
He said his understanding was that the man was 'comfortable' in hospital.
He said: 'Our thoughts are with the gentleman and with his family.'
He said the park had cooperated with an inital investigation with the Health and Safety Executive.
'Out of a matter of courtesy we are keeping the pool closed this weekend,' he said.
