Severe bleeding:
You will want to put pressure on the open wound with a gauze pad or material that will not stick to the wound. Elevate that body part above the heart to slow down circulation only if there are no broken bones. If bleeding still keeps going through your gauze, do not remove it just add more on top of that to try and soak and slow the bleeding down. If an object is sticking out of wound, do not remove, but put padding around it to protect it and keep it from moving around. If bleeding does not stop put pressure on one of the pressure points. There is one on your inner arm and in your groan area. Treat them for shock. Try and get help as soon as possible.
Minor Bleeding:
Put pressure on it until it stops bleeding. Put some type of dressing on it and clean it to keep it from getting infected.
Choking:
If someone is choking and still able to talk or caught, encourage them to continue to try and cough it up. If they stop coughing, wrap your arms around their waist while putting the heel of one hand midway between the navel and the sternum. The other hand should go on top of the first. Pull up and in until it comes out.
Broken bones:
Try and secure it and keep it from being able to move it around. It should be put into a comfortable position and put into a splint. You can make a splint with a blanket or a straight board or stick. Wrap around these straight objects and the broken bone small pieces of cloth to hold the brace on. Do not put a brace on right over where the break is. Only go around the area.
Shock:
Shock can occur when someone is injured, in pain, fear or exhausted. This can be life threatening. Get them into shelter and try to keep them warm but putting blankets or leaves on them. You can also make a fire. Their breathing may increase and can be clammy and cold. Have them rest and try to relax.
Hypothermia:
With a hypothermia case you want to get them into shelter and warmed up. You need to warm their body core up at a steady but not too fast of a pace. Wrap them up in blankets or coats, whatever you have available and try to get warm liquids down inside of them. Only give them the liquids if they can handle drinking it. If this does not work, the best way to warm them up is to have them and another person go in a sleeping bag together with minimal cloths. You should be chest to chest in the sleeping bag to give them your body heat to warm them up. Many of their symptoms are slurred speech, uncontrollable shaking, and clumsiness. People often get hypothermia from exposure to cold weather, wind and getting wet.
Heat Stroke:
This is where the person has been exposed to too much heat and becomes overheated. The person will stop sweating and the face will become flushed. They need to be taken out of the sun and cooled off as quickly as possible. Can poor cold water on them.
