Knowing a little first aid could be life-saving if you see someone lying unconscious.
Too often people don’t do anything because they think they will kill the patient,but by learning simple rules you could make the difference between life and death.
First,you need to find out if they’re unconscious,asleep or drunk,by squeezing the skin between their neck and shoulder and shouting.If there is no response at all,you need to establish if they are dead or just unconscious—sometimes it’s very difficult to tell the difference.
Open the airway by placing one hand on their forehead and gently tilting the head back while lifting the chin.
If there are no signs of life—no obvious pulse and their chest is not going up and down—call an ambulance and then start cardiopulmonary resuscitation(CPR) to maintain(获得)a flow of oxygenated blood to the brain and heart.
Do this by pushing up and down on the centre of the chest,with your hands interlocked together,constantly until an ambulance arrives.
Push at a rate of 100 beats a minute.You can’t harm them by doing this and might just save a life.
