Answer:

AED´s or Automated External Defibrilators are devices that were created to be used by non-medical people when someone suffers a heart arrest. These devices are generally very easy to use, but it is important to understand the instructions, as they are still devices that produce electrical shocks in order to reanimate the heart during CPR. As such, the answers to your questions, with a small explanation, would be thus:

13. How does an AED work? The answer would be, A: It sends shocks to the heart. A Heart arrest, or an arrythmia, are two conditions in which either all electrical conduction stops, or it is so irregular, that the muscles become unable to respond, and thus do not contract as they should. The AED re-starts  the heart´s electrical conduction system by shocking it.

14. Where should you apply AED pads? The best answer here is, D: On bare skin on the upper right shoulder and lower left ribs. The reason is that this is the correct pathway of conduction of electrical pulses in the heart. Clothing becomes an impediment, and a danger, for a patient, especially if it is flamable, as the AED produces electrical shocks to re-start the heart. And the placing of the pads is to direct the current in the right pathway.

15. Hands-only CPR is better than... The best answer would be, A: No CPR. CPR. CPR, or cardiopulmonary resucitation, is a life-saving maneuver and when it can be performed, it must be. If a person feels insecure about conventional CPR, due to the mouth-to-mouth resucitation part, it is much better to at least initiate hands-only, as the pumping of the heart by hand will allow the person to survive, at least, until trained personnel arrives.

Why is pee yellow and what are the causes if its a differnet color?
Free_Kalibri [48]

Answer:

sometimes due to dehydration

Explanation:

Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is.

Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color. Many over-the-counter and prescription medications give urine vivid tones, such as red, yellow or greenish blue.
