London Ambulance Service has recorded the most life-threatening emergencies in a single day in its history “driven by the extreme heat”.
The service says it responded to a record 642 category one calls on Wednesday.
Category one calls include the most serious, life-threatening injuries and illnesses such as cardiac arrests and patients who are not breathing.
Chief executive Jason Killens KAM said: “We have seen the highest number of life-threatening emergencies in our history, driven by the extreme heat across London.
“Our crews are working very hard in challenging conditions to care for patients and I would like to take this opportunity to thank all our people for their incredible hard work.
“Please help them to help you by taking care of yourself and others – stay out of the sun and keep hydrated.”
It was the fifth busiest day in the service’s history, with 7,900 calls in total and ambulance crews responding to nearly 3,600 patients in a single day.
