He was handed to his parents so they could say goodbye but when nurses started removing tubes from his body he began "twitching". Staff tried again to resuscitate him, this time successfully starting his heart 30 minutes after he was pronounced dead.He was handed to his parents so they could say goodbye but when nurses started removing tubes from his body he began "twitching".

Diagnosing death is about excluding all possible signs of life, say medical professionals. But as a body's organs and tissues do not die at the same time there can be doubt about the actual moment of death.Diagnosing death is about excluding all possible signs of life, say medical professionals.

In hospital someone is usually considered dead when there is no electrical activity from the heart or brain, say medics. But even these are not totally reliable indicators.In hospital someone is usually considered dead when there is no electrical activity from the heart or brain, say medics.

Circumstances play a big part in each case, but hospitals have guidelines and procedures to follow in certain situations, says the Royal College of Physicians.Circumstances play a big part in each case, but hospitals have guidelines and procedures to follow in certain situations, says the Royal College of Physicians.
These include the Glasgow Coma Scale (GCS), a standardised points system based on eye movements, spoken responses and other physical movement.These include the Glasgow Coma Scale (GCS), a standardised points system based on eye movements, spoken responses and other physical movement.

All three things are tested and considered separately, then added together. The lowest possible score on the scale is 3, but even that is not definitive as it can indicate a deep coma as well as death.All three things are tested and considered separately, then added together.

When attempts are made to resuscitate someone after a heart attack - as in Woody's case - there are specific steps that must be taken. Eight reversible causes have to be checked one at a time before someone is pronounced dead.When attempts are made to resuscitate someone after a heart attack - as in Woody's case - there are specific steps that must be taken.

    Checking all the possible causes can take time, anything up to 45 minutes in extreme cases. The cut-off point for resuscitation - when a person is pronounced dead - is when all eight have been checked and there are still no signs of life.Checking all the possible causes can take time, anything up to 45 minutes in extreme cases.

    "Sometimes death is diagnosed quickly and in other cases it can take much longer, usually when the person is in hospital and there is more equipment to try and restart the heart," says nurse and resuscitation trainer, Alan Samuels."Sometimes death is diagnosed quickly and in other cases it can take much longer, usually when the person is in hospital and there is more equipment to try and restart the heart," says nurse and resuscitation trainer, Alan Samuels.
    "Normally the longer resuscitation goes on, the less chance there is of someone surviving, which is what makes the baby's case even more remarkable.""Normally the longer resuscitation goes on, the less chance there is of someone surviving, which is what makes the baby's case even more remarkable."
    Patients who have hypothermia or are drugged can seem dead. It can be difficult to feel a pulse if the heartbeat is very slow.Patients who have hypothermia or are drugged can seem dead. It can be difficult to feel a pulse if the heartbeat is very slow.

    Size is also a factor, as it is sometimes harder to hear a heart beat of a heavier person as there is more fat and muscle between the medical apparatus and the heart.Size is also a factor, as it is sometimes harder to hear a heart beat of a heavier person as there is more fat and muscle between the medical apparatus and the heart.

    ...which is the reason I want to be cremated. I remember watching a programme when I was younger which had a man waking up to find he was in his own coffin, 6 feet under. At least if they make a mistake and I'm alive, it won't take long to prove them right and me wrong.Sarah, Cannock, Staffs
