Ella McCauley, 21, who works in Rugby, had recently been promoted, with her boss asking her to complete the course before she started her new role.

Four days later, Ms McCauley was called on while at work to help a man called David who had experienced a cardiac arrest.

Ms McCauley said performing CPR in a real life emergency was "like something out of film".

She's been speaking to ÃÛÑ¿´«Ã½ CWR presenter Vic Minett.
