Science, Technology and Medicine open access publisher.Publish, read and share novel research. The Glucose Tolerance Test as a Laboratory Tool with Clinical ImplicationsPaul Ernsberger and Richard J. Toward the bottom of this page is a practice exam, almost the same as what you will see when you come to the campus to take the on-campus exam.
The ear thermometer (on the right) doesn't contact the ear drum, so it is measuring the amount of infrared light emitting from the ear.
This digital thermometer measures the room temperature and can take readings of the ear or forehead. The ear and forehead measure the amount of infrared light (heat radiation) coming from the ear drum or the skin.
I've seen infrared based thermometers like in the picture used to measure the temperature of a wide variety of items at a distance. The science behind these devices is the use of an LED light and a photodiode (a light detector) that looks at the level of two forms of hemoglobin.
Because of the heart beat, the level of hemoglobin in capillaries in the fingers are expanding and contracting with each heart beat. Besides useful for people who have breathing problems, these are being used by pilots and mountain climbers who are at altitudes where oxygen levels are low and monitoring their oxygen saturation would be wise. When a nurses takes someone's pulse, they pump up the cuff to the point where they can't hear the pulse. The low reading is called the diastolic pressure, which is the pressure when the heart is as rest. You may be surprised that there is a blood pressure cuff that uses an iPhone for the digital readout and storage. The science behind these modern blood glucose (sugar) meters is to draw in a set amount of blood. I was surprised to see a home test for A1C because I heard doctors describe it as a specialized test. I couldn't find out exactly how these A1C test strips and meter work, but I imagine it's similar to the way the blood sugar test strips and meter work.
Protein in the urine (proteinuria) can indicate a kidney disease or some other serious condition. Ketones in the urine (ketonuria) indicate the body is having trouble using sugar for energy, so it's using fat and proteins instead. Blood in urine (hematuria) gives people some anxiety but isn't always a reason for concern. Another way the density of urine is determined is by measuring how much it bends light (refracts light). When I worked at the Phoenix Crime lab back in the 70's, the breathalyzer available at that time used a solution of sulfuric acid and a salt called potassium dichromate.
I think the coolest (but not the cheapest) personal medical device is the portable ultrasound imaging machine. What sensor in the left thermometer is responsible for detecting the temperature and name one of its ingredients?
Answer: Percent (%) that hemoglobin is saturated (S) with oxygen (O2) in a peripheral (p) part of the body (for example, fingers).
The below chart is from a urine test strip that measures the concentration of five different substances. If a person has a high reading for ketones, their urine (and breath) is likely to smell like what? The home pregnancy test will measure the presence of the hormone called human chorionic gonadotropin. Answer: A band at the T region is positive indication of the hormone and therefore indicates the one tested is pregnant. Answer: It means the test is complete and one should then look to see if a band is at the T region.
Answer: Cocaine, amphetamine, THC (marijuana), opiates like opium, morphine and heroin, and PCP. THC is tetrahydrocannabinol, which is the psychoactive chemical in the cannabis plant (marijuana).
Unlike the pregnancy test, a band of color showing up at the T region on a drug test indicates what? Answer: Methamphetamine is the same as amphetamine but methamphetamine has an extra methyl group on it. When ethyl alcohol (ethanol) is completely oxidized (burned) in a fuel cell, 12 electrons are produced as electrical current for each molecule of ethanol.
On the exam, you might be asked to balanced one or two of the compounds in the equation, but not the whole equation.

As the alcohol gets converted to acetic acid, the potassium dichromate gets converted to chromium(III) sulfate, Cr2(SO4)3.
The initial color of the solution is yellow.  What is responsible for the yellow color? After the alcohol is turned into acetic acid, the solution is dark green.  What is responsible for that color?
Let's say you were trapped in a mine and you took 1.2 liters of water and did electrolysis on it to get some oxygen, how many grams of oxygen would you get? Which is the most predominant element in water if you base it on its percent of the weight of water? Which is the most predominant element in water if you base it on its percent of the number of atoms in water? If you are charged or arrested for DUI or Driving Under the Influence, It is very important to call an experienced DUI Lawyer immediately. Email communication by you through this web site does not establish an attorney-client relationship. Blood glucose levels : testing and normal range, A blood glucose test measures the amount of a type of sugar, called glucose, in your blood. Blood sugar – wikipedia, the free encyclopedia, The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. Normal blood sugar levels chart for adults, This simple chart shows target blood sugar levels for before and after meals, after fasting, before exercise, and at bedtime, as well as an a1c target..
Blood test results with normal range reference chart, Blood test results, normal blood test ranges and blood test results for female and blood test results for male, blood testing and rare blood testing results.. Glucose tolerance test: untreated SHROB versus SHROB treated with antihyperglycemic agents and one antihypertensive agent.
My motivation for doing it was partly because I think the average person should take advantage of the tools of science.
That's a good opportunity to monitor health needs at home and to learn more about the science behind these devices and tests. As electronics got more miniaturized and sophisticated, devices like these have gotten cheaper and common place.
Even after she got over the pneumonia, she would often complain about not being able to breath.
A pressure of 126 mmHg meant the person's heart beat had the pressure to raise the mercury in the tube to a height of 126 millimeters (about 5 inches). The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes and to gauge how well a person has been managing his or her diabetes.
The more the inner tube extends above the surface of the urine, the more dense the urine is. Anti-bodies are proteins created by the immune system to neutralize a foreign bacteria or virus, but also can attach itself to a specific protein. Dark green is after reacting with alcohol, which forms the dark green chromium(III) sulfate.
The device is a personal or portable breathalyzer for measuring blood alcohol content in the blood. Even though it's called the personal ultrasound device, it's marketed more to doctors than the average consumer, but eventually it will be affordable to consumers.
It means that it either adds oxygen atoms or it behaves like oxygen, which is to strip electrons away from things. The reading is the percent of the hemoglobin in red blood cells that are coated with sugar (glucose).
We, at Law Offices of Tony Forberg have handled numerous DUI and Driving Under the Influence Cases.
If blood test results are coming back in the upper ranges on the is chart further medical treatment by a doctor is probably indicated. The exam will ask questions about what you learn below plus there will be some questions from the online exam.
As the temperature goes up, the electrical resistance comes down and that is converted to a temperature reading on the display. For this wrist version, you can see the wave which is the changing levels of hemoglobin from which the pulse can be calculated.
Using a blood pressure monitor like the one in the picture could have warned him that his blood pressure was too high despite the medication he was taking. These are often placed on the wrist but not always as accurate as those placed on the upper arm. The glucose in the blood reacts with an enzyme called glucose oxidase that pulls 2 hydrogen atoms off of the glucose molecule. The science behind it must be like the blood glucose strips and meters, but with an additional enzyme to identify the level of cholesterol. The computer chip in the devices translate the degrees the light bends into density (specific gravity) of the urine. As the alcohol got converted, the potassium dichromate got converted to chromium(III) sulfate, Cr2(SO4)3.

Since people don't breath out hydrogen, then this test uses ethyl alcohol as the fuel to generate electricity.
The amount of alcohol required to become impaired differs according to numerous factors, including but not limited to how fast you drink, your weight, your gender, and how much food you have in your stomach. This information is not intended to create, and receipt or viewing does not constitute, an attorney-client relationship.
As you can see the blood sugar amount increases after a meal when the food is digested and glucose is absorbed into the blood. However, after realizing how unsafe these were, you can't really find these in the stores anymore.
One type of thermocouple is used by your gas water heater or gas oven to sense if the pilot light is on.
In the hospital I noticed they used a device called the Pulse Oximeter to measure her pulse and oxygen levels.
That might have saved him the devastating effects from the stroke that he still suffers with.
The test strip has a reagent (a chemical that reacts with some other chemical) that is specific for acetoacetic acid (a common ketone found in urine). This is the same kind of instrument used to measure the charge of a battery (by measuring sulfuric acid density). Saliva is placed on the bottom indentations, and it travels up the strip to where the letters are. To make that conversion, an oxygen atom is added to the alcohol and a hydrogen atom is removed.
The blood sugar level falls as insulin does its work of moving the glucose from the blood in to tissues needing it for food. SHR were fed a supplementary sweet drink to induce dietary obesity in these genetically lean rats. However, when computers got smaller and less expensive, it was possible to own a computer and take advantage of everything it could do.
So the Breathalyzer had a light pass through the solution and the change in the color correlated with the amount of alcohol in the breath. This pattern is a normal occurrence as glucose is needed in the body for proper brain functioning as well as for fuel for muscles and other cells. It cost $200, but was very useful in discovering that her oxygen levels were truly very low.
So we bought one of these automatic blood pressure monitors and checked his blood pressure about 3 times a day.
One problem density can indicate is an imbalance in electrolytes such as potassium and sodium ions.
The electron flows down a wire and is measured with an electrical meter which shows up as a reading on the display. To find the amount of alcohol in the blood, the machine multiplied by 2100 because the blood always has 2100 times more alcohol in it compared to the alcohol in the breath. Keep your glucose levels functioning like the chart above and everything should be just fine. The metals that are selected to be sandwiched together to make these thermocouples can be chromium, nickel, copper, tungsten, and platinum.
This prompted the doctor to prescribe a portable oxygen concentrator that gave her pure oxygen when she needed it.
Again specific antibodies for each drug is present in the strip along with a dye attached to the antibody. The more alcohol present the more electron current will flow, which makes the reading go up.
As they are exposed to heat, they generate an electrical voltage, which can be converted to a reading on the display window. Blood cells live for 2 or 3 months, which is why this test gives you an idea of the blood sugar level over the last 2 or 3 months. Apparently the drug attaches to the antibody and dye and creates a group that is not carried along by the urine to the T area.
This device is called a fuel cell because it is using alcohol as a fuel to generate electricity.
Only if the drug is NOT present does the urine carry the antibody and dye combination to the T area. In the future, your cellphones will likely run off of drinking alcohol (ethyl alcohol) or methyl alcohol because alcohols can produce a lot more electricity for a longer period. Again, if the antibody-dye combination forms a line at the T area, then that drug was not present. In other words, your cellphone will stay charged for a month without adding more alcohol to it.
