Check yourself first: If you have been injured in the accident, first check yourself for any injuries. Try to assess how well you can move you properly, and if you experience symptoms such as dizziness etc. Remember you need to be fit enough to help others.
Check the other person for injuries: If other people are injured, first assess the extent of his/ her injuries. Treat the quietest person first, they are usually more seriously injured or cannot breathe.
People who can talk or scream, on the other hand, can breathe therefore can be treated a little later.
Ask for the patient's name, if they respond to it means they are able to understand the situation and have most likely not suffered a severe head injury.
Look for signs of breathing: Check if the person who has met an injury is breathing and if he/she has a pulse.
Perform life saving techniques: If there is no pulse, start cpr or ear. Keep the person's neck straight to start EAR (External Air Resuscitation) or CPR (Cardiopulmonary resuscitation).
There are 3 types of EAR; Mouth-to-mouth, Mouth-to-Nose, Mouth-to-Mask. You could read more about how to perform EAR AND CPR here.
Call for help: Immediately call for an ambulance or rush the person to a hospital. Once you know more about the patient's condition you will be in a better position to tell the doctors about his/her condition.
Check for obstructions : If you do not hear any breath sounds, check his/her mouth for any obstructions. If there is something obstructing the airway, use your index and middle finger to clear the airway. Before the ambulance arrives.
Keep the person warm: Usually accident victims feel excessively cold due to shock. Keeping them warm is essential to survival. You can use whatever you have to do this, such as a T-shirt, jacket.
Avoid feeding the person: Do not give the person any water, food or other fluids through the mouth, it could lead to the patient choking.
Deal with open wounds: If there are extensive wounds, try to control the bleeding using pressure to the area using a cloth.
5 tips while shifting the accident victims to hospitals :
Make sure the person has a pulse and is breathing on the way to the hospital. If he/she stops breathing, be prepared to start CPR or EAR in the vehicle.
If there is only a limb injury, the patient can be transported in a sitting position.
Keep the person's neck and back straight. You could place a rolled up towel or thick cloth under the neck for better support.
Ensure that the person is lying down flat.
In case of a bleeding injury, lift the injured part above the person's body level and apply pressure on the region. Keep applying pressure till you reach the hospital. This helps control and eventually stop the bleeding.
