Restart a Heart day at Crossfit London UK


Each year the Resuscitation Council runs  “Restart a Heart” day in October. Crossfit London, with help from the St John Ambulance ( Leytonstone Branch), will be running an evening of free CPR training at its Bethnal Green venue from 5.30pm on Thursday 17th October.

Every 30 minutes we will have room to teach 8 people how to do CPR and use a defibrillator. Unlike a lot of London Gyms, we actually have our own defibrillator onsite. You might as well know how to use it.

So just rock up at 5.30/6/6.30/7/7.30/8pm and head for reception.

This is mainly for our members but all are welcome but  the address is railway Arch 30, 150 Buckhurst St E1 5QT

Here is are some fun facts about Cardiac arrest

  • A cardiac arrest is when the heart’s electrical supply is interrupted resulting in the heart stopping pumping blood around the body.
  • The heart is a pump, which supplies oxygenated blood to all of the body, which is vital for bodily function.
  • If someone’s had a cardiac arrest, they’ll be unconscious, not breathing or not breathing normally.
  • Call 999 immediately.
  • All the cells in your body require oxygen to survive. They also require a good supply of nutrients and the rapid removal of waste products. Oxygen and nutrients are carried
around the body in your blood, which is pumped by your heart. In your lungs, oxygen enters your blood stream and carbon dioxide (a waste product) is removed in a process known as gas exchange. A cardiac arrest is when your heart stops beating. This is not the same as a heart attack, although a heart attack may lead to a cardiac arrest.
  • There are numerous causes of cardiac arrests, including:
    • –  A disturbance in the heart rhythm
    • –  Drugs/poisoning
    • –  Heart disease/a heart attack
    • –  Traumatic injury/blood loss
    • –  Anaphylaxis (allergic reaction)
  • If a cardiac arrest occurs, blood will stop circulating around the body. Breathing will also cease as well though it may not stop completely for several minutes. Without a supply of oxygen, the cells in the body start to die. Brain cells are incredibly sensitive. After about three to four minutes of no oxygen, brain cells will begin dying, leading to brain damage and death.
  • The purpose of CPR is to keep oxygenated blood owing around the body to keep the vital organs alive. CPR itself will not restart someone’s heart; it just keeps them alive until a defibrillator arrives. A defibrillator is a device that delivers an electrical shock to the heart to restart it.
  • Over 30,000 people suffer cardiac arrests outside of hospital in the UK every year. If this happens in front of a bystander who starts CPR immediately before the arrival of the ambulance, the victim’s chances of survival double or triple.
  • Today, if you suffer a cardiac arrest out of hospital in the UK, you have less than a one in ten chance of surviving.
  • Chain of Survival – Early Recognition, Early CPR, Early Call for Help, Early Defibrillation. A chain is only as strong as its weakest link. Bystander intervention is vital to improve outcomes.
  • Compressions should be at the rate 100-120 per minute, 5-6cm compressing the chest and a ratio of 30 compressions to two breaths pressing on the centre of the chest between the nipples.
  • Chest compressions and ventilations slow down the rate of deterioration of the brain and heart.
  • If a bystander is unwilling to do mouth-to-mouth, hands-only CPR is fine, with the simple message ‘hard and fast’ in the centre of the chest to the beat of ‘Staying Alive’. It is most likely that the students we are teaching will see one of their family members in cardiac arrest so they will be more inclined to deliver rescue breaths if it is a family member.
  • With each minute’s delay of delivering a defibrillation shock to a shockable cardiac arrest, the chances of survival decrease by 10-12%. Public Access Defibrillators are very easy to use and widely available.
  • Some people are afraid of performing CPR for fear of worsening the situation but if the victim does not receive CPR there is a good chance that they will die. On occasion, when performing chest compressions it is possible that ribs may be heard to crack, this is normal and not something to worry about.
