Paramedic students are raising money for an air ambulance service by running a 24-hour CPR marathon on Valentine's Day.
Students and staff at the University of Brighton will perform the lifesaving procedure non-stop to raise funds for the Air Ambulance Charity Kent, Surrey, and Sussex (KSS).
They will also provide hands-on training for the wider community at the event which starts from 09:00 GMT on Friday at the university's Paramedic Science Suite.
Cardiopulmonary resuscitation - or CPR - is used for restarting the heart or helping people breath again.
The event was organised by students who hope to raise awareness of the importance of CPR as well as helping KSS.
