11. The recommended compression-to-ventilation ratio for adult CPR is 30 compressions followed by 2 breaths.<br />12. To perform the Heimlich maneuver on a conscious adult, stand behind the person and wrap your arms around their waist. Make a fist with one hand and place it slightly above the person's navel. Grasp your fist with your other hand and perform quick, upward thrusts to dislodge the object.<br />13. Signs that someone is having a heart attack include chest pain or discomfort, shortness of breath, nausea or vomiting, lightheadedness, and pain or discomfort in the jaw, back, or arms.<br />14. Gloves should be used while providing first aid to protect both the first aider and the victim from the transmission of bloodborne pathogens.<br />15. The recovery position is when a person who is unconscious but breathing normally is placed on their side, with their bottom arm and leg straightened out and their top arm positioned in front of their body. It should be used when a person is unconscious but breathing normally.<br />16. To treat a burn, cool the affected area with cool (not cold) water for at least 10 minutes. Do not use ice or very hot water. Burns are classified into three degrees: first-degree burns affect only the outer layer of skin, second-degree burns affect the outer layer and the underlying skin, and third-degree burns affect deeper tissues and may appear white or charred.<br />17. Symptoms of shock include rapid, weak pulse, rapid, shallow breathing, cold, clammy skin, and confusion or dizziness. To respond to shock, lay the person flat, raise their feet about 12 inches, and keep them warm and comfortable.<br />18. It is important to stay calm during a first aid emergency to think clearly and make the best decisions for the victim's care.<br />19. To control severe bleeding, apply direct pressure to the wound with a clean cloth or bandage. If the bleeding does not stop, apply a tourniquet or pressure point.<br />20. An allergic reaction can be recognized by symptoms such as hives, swelling, difficulty breathing, or anaphylaxis. To respond to an allergic reaction, call emergency services and administer an epinephrine auto-injector if one is available.
