Performing CPR(continued) • ABCDs of CPR • A stands for airway • B stands for breathing • C stands for circulation • D stands for defibrillation (continues)
Performing CPR(continued) • Evaluate victim’s condition before starting CPR: • Check if patient is conscious • If unconscious, check for breathing • If not breathing, place victim on back • Open the airway by using the head-tilt/chin lift or jaw-thrust maneuver (continues)
Performing CPR(continued) • Look for chest movement • Listen for breathing • Feel for movement of air from the nose or mouth • If not breathing, give two breaths • Make sure breaths are effective • Then check the carotid pulse (continues)
Performing CPR(continued) • Correct hand placement is needed before performing chest compressions • Various methods of CPR used • One-person adult rescue for adult • 30 compressions followed by 2 ventilations (30:2 ratio) (continues)
Performing CPR(continued) • Two-person adult rescue for adult • 30 compressions by one rescuer followed with2 ventilations by the second rescuer (30:2 ratio) • CPR for infants (birth to one year) • 30 compressions followed by 2 ventilations for one rescuer (30:2 ratio) • 15 compressions followed by 2 ventilations for two rescuers (15:2 ratio) (continues)

Controlling Bleeding • First priority because victim can bleed to death quickly • Bleeding can come from arteries, veins, or capillaries • Observe standard precautions (continues)
Controlling Bleeding(continued) • Direct pressure • Pressure applied with gauze- use a clean cloth if sterile gauze not available • Elevation • Above the level of the heart- gravity helps to stop bleeding • Pressure bandages • Direct pressure and elevation are used • Pressure on pressure points • Main blood supply to the affected area helps minimize blood loss
Controlling Bleeding • Do not disturb clots • Clots are a natural defense in the bodies attempt to stop bleeding • Do not remove dressings • May result in additional bleeding • Do not clean wound • May also lead to further bleeding
Minor Wounds • First priority— • prevention of infection • Wash your hands thoroughly before caringfor wound • Put on gloves • Wash the wound with soap and water • Rinse the wound • Use sterile supplies

Types of Shock • Psychogenic • Severe emotional distress- anger, fear, grief cause dilation of blood vessels • Septic • Infections or poisoning causing severe vasodilatation • Metabolic • Causing changes in normal balance or homeostasis of the body • Loss of fluids from extreme vomiting, diarrhea, and heat • Neurogenic • NS can not control the size of blood vessels • Injury and/or trauma to the spinal cord
Signs and Symptoms of Shock • Skin is pale or bluish-gray and cool or cold to the touch • Diaphoresis • Rapid and weak pulse • Respirations rapid, shallow, and may be irregular • Blood pressure very low or unobtainable (continues)
Signs and Symptoms of Shock(continued) • General weakness • Anxiety and extreme restlessness • Excessive thirst • Nausea and/or vomiting • Blurred vision or changes in appearance of eyes
Treatment for Shock • Goals of treatment- Shock states are life threatening • SEEK MEDICAL ATTENTION STAT • Improve circulation—especially – to the heart and brain • Provide oxygen • Maintain body temperature • *****Reduce effects of or eliminate the cause
Shock • Positioning of victim • Best position is supine with legs elevated 12 inches • The position for treating shock must be based on the patients injuries • Maintain body temperature • cover the victim with blankets to prevent chilling and exposure to cold– avoid overheating the victim • Avoid food or drink • DO NOT GIVE anything by mouth • Other principles of care
