There are two general types of mercury thermometers that measure body temperature: The main reason they are not longer recommended is that mercury can poison you. It has been reformatted by the Brookside Associates for wider distribution.While this material may be very useful to students of the health sciences, completion of this course does not imply competence or certification.I welcome visitors to this site who have no nursing or medical background. The Celsius reading is 37.4º C.This course is intended for use by nursing and medical professionals, and those in training for those professions. The kink stops the mercury from falling, giving the user/reader of the thermometer time to read the highest temperature recorded. The mercury can easily penetrate into the pile of carpets, in cracks of floors, in the gap between the baseboard and the floor.
The newest and most expensive thermometer on the market, temporal thermometers read heat coming from the temporal artery, which is right under the skin of your forehead. On the Celsius scale; however, there are nine shorter marks between each pair of long marks. Any temperature over 37.7C (100F) is classed as a fever.Hypothermia develops if the temperature falls below 35 degrees C (95F).Body temperature varies according to how active your child has been and the time of day: it is lowest in the morning as there is little muscle activity during sleep, and highest in late afternoon.When your child has a fever you should take his temperature again after 20 minutes, just in case it was only a transitory peak.Digital thermometers are easy to use with children of all ages and are safer than mercury thermometers to use in the mouth, since they’re unbreakable. The Brookside Associates does not necessarily endorse or agree with all of the clinical opinions expressed, as those opinions belong to the authors.2. How to Use the Thermometer Practice Flash Cards: Click on the first image below to enlarge. When the sensitive side is placed on the forehead, the numbers (your child’s temperature) light up.Liquid crystal thermometers aren’t as accurate but are safe and easy to use and give you enough of a general idea to allay anxieties.Mercury thermometers are the most accurate means of measuring but rarely used now. Mercury thermometers are no longer recommended because they can break and allow mercury — which is toxic — to escape. Since mercury is highly toxic, using them in food or in the body is discouraged. Hold the thermometer by the top end and shake it down sharply until the mercury falls below the 35C (95F) mark.
Each small mark shows an increase of one-tenth of a degree Celsius (0.1º C).For example, the third short mark past the 38º C line denotes a temperature reading of 38.3ºC. For reliability, it is better to prepare one liter.Qsota does not provide medical advice, diagnosis or treatment - In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. Common household uses of mercury thermometers include fever thermometers and oven, candy and meat thermometers.Mercury thermometers may be used in many applications, including chemical experiments, water and acid baths, blood banks, ovens and incubators.EPA has launched an effort to reduce the use of mercury-filled non-fever thermometers used in industrial settings where suitable alternatives exist.
There are two main reasons.First, the vacuum itself is dirty with particles of mercury, and use them in the future it will be impossible and dangerous.Secondly, the filters of a vacuum cleaner won’t keep all mercury, and most of it has already led once again will be in the room and settles on all possible surfaces (from which it will be difficult to collect), and lots of it gets into your lungs.Once you have collected all of the mercury needs to be treated very gently and carefully. At one end of the tube is a reservoir of mercury.
Mercury is bad for your health, as well as for the water, wildlife, and waste systems on earth. In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube.
The most similar alternatives to mercury fever thermometers are battery- and solar-powered digital thermometers.
