Master First Aid
It is possible that you are not able to receive an urgent care during times of disaster such as earthquake, which involves a number of injured people at the same time. Let's learn First Aid for an emergency.
Hemostasis (Stop bleeding)
Although you may be in shock to see large amounts of blood, it is important to stay calm and stop the bleeding. Normally it is safe for adults to lose about 400ml of blood. Life becomes critical if an adult loses more than one third of the body's blood (1500ml). First, observe how much bleeding there is and from where the bleeding comes.
< Direct Pressure Hemostasis >
Cover the wound with clean gauze or cloth. Directly put pressure on the wound.
< Indirect Pressure Hemostasis >
When you have the condition of blood pouring out but are not quite ready for the direct pressure hemostasis, use this method temporarily by pushing the artery closest to the heart from the bleeding area towards the bone.
You may face other cases where someone needs mouth-to-mouth breathing or heart massage. Learn how to give CPR through classes given by the municipal office, fire department and Japan Red Cross. Major scuba diving groups may give classes as well.
