Cardiopulmonary resuscitation
Cardiac arrest is the most time-critical medical emergency an anaesthetist may face. Effective basic
and advanced life support measures must be applied as early as possible to maximise the chance of
survival and minimise hypoxic neurological damage. It is a series of well-defined steps &protocols to revive a
collapsed patient ,to deliver oxygen to the heart &brain &to restore native circulation &ventilation
On normal inspiration, a person breathes in approximately 21% oxygen. The body uses between 4-5% of this amount for its normal functions. Therefore, on expiration a person breathes out approximately 16% oxygen.
Cardiopulmonary resuscitation (CPR) is Expired Air Resuscitation (EAR) used in conjunction with External Cardiac Compressions (ECC). CPR is the most effective form of active resuscitation available today, and is used universally by first aider’s and medical personnel alike. The technique is used to ‘buy time’ in resuscitation of casualties in cardiac arrest.
EAR provides oxygen to the casualty’s lungs and blood whilst external cardiac compressions, when applied correctly pumps the oxygenated blood around the body. Effective CPR can sustain a casualty until more expert medical treatment is available.
You might not think of yourself as having lots of muscles, but there s one super-powerful muscle in your body you absolutely depend on: the tireless blood pump in your heart. If your heart stops beating properly and blood stops flowing, your brain starts to lose its oxygen supply and you can die within five minutes. That s why people who suffer cardiac arrest(when their heart stops or goes into a dangerously abnormal rhythm) need emergency medical treatment. CPR (cardiopulmonary resuscitation) can help maintain the flow of oxygen to the brain, but getting the heart restarted and working normally often requires defibrillation with an electric shock.
