INPUT ARTICLE: Article: If two other people are starting to fight, you should try to diffuse the tension by appearing relaxed. Use a soothing tone of voice, nonthreatening body language (for example, keep your hands raised in front of your chest), and slow movements. Fights move quickly so you won't have a lot of time. You need to determine how serious the situation is, if you are in danger, whether you need to call for help, and what strategies might work best to stop the fight in this particular situation. Try to determine whether anyone has a weapon or is likely to reach for an object to use as a weapon (for example, a bottle in a bar fight). If so, call the police and do not intervene. Try to move other onlookers, especially children, to safety. Notice whether the fighters have "back up," often in the form of onlookers who are egging on the fighters. Gang fights and similar situations are unpredictable and you should not try to intervene. Look around for any large objects that you can push between the fighters, like trash cans, desks, or anything else that is big but possible for you to quickly move into place. If either fighter has a weapon of any kind, call the police and do not try to intervene. You should also call the police if you are physically unable to restrain a fighter or fear that your safety would be in jeopardy if you intervened. Unless a police officer happens to be in the vicinity, it may be too late by the time they arrive. If it is safe to do so, try to break up the fight yourself while you wait for them to arrive. If there is anyone else within hearing range, get them to help you break up the fight before attempting to do it yourself. In situations like this, onlookers don't generally stop to help unless you tell them specifically. So instead of yelling "Someone help me!" look someone in the eye and say "Help me stop the fight!" If possible, choose someone who is larger than the fighters and looks strong and athletic. But in a pinch, any able-bodied adult will do! Don't leave the scene of a fight to get help unless you have to, especially if the fighters are juveniles. If you're at school or in another setting where there are no adults present, you can always send a kid to get another adult. This recommendation is only for situations in which both fighters are unarmed and the fight has not escalated to full-on blows. Be aware getting between two fighters is a risky choice, and you may be injured. You should also know that in many schools, it is illegal for teachers to touch students, even to intervene in a fight. When two people are gearing up for a fight, they tend to confront each other with their chests puffed and their shoulders back, staring directly into each other's eyes. Put your body between them during this stage, and you can help break the invisible tension between them. If one of the two fighters is "picking a fight" or purposely antagonizing the other, this is the person you should attempt to redirect and calm. Use a soothing voice and try to reason with the person. Most people do not want to fight, but fear looking weak if they back down. For that reason, it's your job to give the antagonist an "out" or a reason to not fight the other person without losing face. If you know the person, use his or her name, and try phrases that will resonate like, "What about your kids?" or "Do you want to go back to jail?" If you do not know him or her, try soothing phrases like, "It's OK, calm down," or "Think about what you're doing; do you really want to face the consequences of a fight?" This can be very difficult unless you have had training in self-defense or martial arts of some kind, or if you are out of shape or smaller than the attacker. It can also be risky, as you might get injured or be accused of hurting someone. However, there are times when you must intervene to stop someone from hurting someone else. Get behind the attacker and use a half-nelson grip to take her down. A half-nelson is a wrestling technique designed to take an opponent to the ground. To execute this move, pass your dominant arm under the attacker's arm on the same side (that is, your right arm under her right arm, or your left under her left). Reach your arm up over her back and grip her neck. Pin her other arm using your free arm.

SUMMARY: Stay calm. Assess the situation quickly. Call the police. Get help from another onlooker. Get between the fighters. Face the antagonist. Restrain an active fighter.

INPUT ARTICLE: Article: Use a scale that will give you the value in kilograms. Because children's weights change rapidly, especially right after birth, it is important to have an up-to-date weight. If your scale gives the weight in pounds, then you will need to covert the values to kilograms. Otherwise the answer will not be accurate. 1 pound equals 0.45 kilograms. If you know the child's age, you can use these values: A newborn that is only 15 to 30 minutes old will have an average blood volume of 76.5 milliliters of blood per kilogram. A newborn that is 24 hours old has 83.3 milliliters per kilogram. A three month old has 87 milliliters per kilogram. A six month old has 86 milliliters per kilogram. A child one to six years old has 80 milliliters per kilogram. A ten year old has 75 milliliters per kilogram. A fifteen year old has 71 milliliters per kilogram. As teens reach adult sizes and proportions, their blood volume will be the same as that of adults. Multiply your child's weight times the average value for his or her age group. The result will be your child's estimated blood volume. The values may differ slightly when you use a different method of calculation. The accuracy of the calculations may also vary slightly based on whether these averages were calculated from a population that is similar in body side and growth patterns to your child.

SUMMARY:
Weigh the child. Determine the average blood volume per weight. Calculate the blood volume.
