Second-degree (partial thickness) burns affect both the outer and underlying layer of skin. They cause pain, redness, swelling, and blistering.
Third-degree (full thickness) burns extend into deeper tissues. They cause white or blackened, charred skin that may be numb.

Convulsions are when a person's body shakes rapidly and uncontrollably. During convulsions, the person's muscles contract and relax repeatedly.The term "convulsion" is often used interchangeably with "seizure," although there are many types of seizure, some of which have subtle or mild symptoms instead of convulsions. Seizures of all types are caused by disorganized and sudden electrical activity in the brain.

CPR stands for cardiopulmonary resuscitation. It is an emergency lifesaving procedure that is performed when a person's own breathing or heartbeat have stopped, such as in cases of electric shock or drowning.CPR is a combination of rescue breathing, which provides oxygen to the victim's lungs, and chest compressions, which keep oxygenated blood circulating until an effective heartbeat and breathing can be restored.Permanent brain damage or death can occur within minutes if blood flow stops. Therefore, it is critical that blood flow and breathing be continued until trained medical help arrives.CPR techniques vary slightly depending on the age or size of the patient.See also: CPR for child age 1-8 yearsCPR for infant under 1 yearCPR for person over 8 years
