A jury has heard of the dramatic moment doctors took the decision to give up the battle to save Diana, Princess of Wales' life.
Anaesthetist Daniel Eyraud said medics agreed "by common consent" to abandon attempts to restart the Princess' heart after prolonged surgery to stem internal bleeding.
Diana's inquest in London was told how staff at Paris' Pitie-Salpetriere Hospital carried out cardiac massage constantly as surgeons attempted to clamp a ruptured blood vessel next to Diana's heart.
But after repeated electric shocks also failed to revive the Princess, medical staff accepted that the battle to save her life had been lost.
He said in a statement read to the jury: "We decided by common consent to stop heart massage as it was completely impossible to restore cardiac activity after such a long period of arrest.
"From that point, the Princess was pronounced dead."
He said he could not recall the exact time when the decision was taken but said staff had treated her for "a few hours".
The jury have already been told that Diana went into cardiac arrest at around 2.10am and was finally pronounced dead at 4am.
"I personally believe we did everything possible to save the Princess with the appropriate means."
The court heard that the car crash in the Pont de l'Alma Tunnel in Paris in the early hours of August 31 1997 left Diana with a ruptured blood vessel causing massive internal bleeding.
