If your tube becomes clogged, try to gently flush it with warm (not hot) water. The water may need to sit in the tube for 5 to 10 minutes. Do not push hard when trying to unclog the tube, it may break. If this does not work, your doctor may need to change the tube. Site Infection Like any wound, your PEG site may become infected.
Nitroglycerin is a smooth muscle relaxer and vasodilator. This drug provides myocardial oxygen which reduces myocardial wall tension. Reduction in myocardial wall tension corresponds with lower systolic pressure. Beta blockers are antagonistic beta receptor blockers which act on the heart to reduce the amount of work the cardiac muscles have to do. By blocking beta receptors, the heart rate will be slowed and reduces demand for oxygen and contractility.
These are placed under the top lip, between the cheek and the gum and let it dissolve), and a spray which is held up-right as close to the mouth as possible, hold it a close to the mouth as possible and spray, then close the mouth immediately. Do not swallow. Side effects of Nitroglycerin are: headache, upset stomach, rash, dry mouth, flushing or feeling very warm suddenly, dizziness, blurred vision, chest pain (agnia) and fainting. Nitroglycerin is used along with other drugs to treat Congestive Heart Failure and heart attacks. Congestive Heart Failure (CHF) happens when the heart’s inablility to strongly pump blood through the heart causes the fluid called congestion to buildup in the lungs and other body tissues.
Some might think that by squeezing the bottle, Mr. Squiddy would go up with the water however, he would go down due to the pipette being used. The pipette had a little air bubble at the top of it, when the bottle was squeezed the water filled into the pipette creating an increase in pressure and a subsequently decrease in volume causing Mr. Squiddy to sink. When released, the high pressure subsided and he floated back up. In the crushing cans demo the cans were heated up with a little water inside and set to boil until steam appeared. Once the can was hot enough it was quickly placed in a bowl of ice cold water and the can crushed itself.
Caffeine & Alcohol Effect on the Water Flea Heart Rate Abstract In this study, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine and alcohol on heart rate. There was a control group used along with the alcohol and caffeine to ensure the results were more accurate. The prediction was the introduction of alcohol and each increased concentration of alcohol, would decrease heart rate and the introduction and subsequent increased concentrations of caffeine would increase heart rate. The results of this experiment proved the prediction to be correct with the alcohol, but the results from the caffeine were hardly noticeable. Methods & Materials
Add the HCl SLOWLY to the magnesium by running it down the side of the beaker. Adding the acid too quickly will result in the spattering of the acid. Write down any observations of the reaction. 6. After all the acid has been completely added and the reaction has stopped, use a pipette to add a few extra drops of acid into the beaker until the reaction stops.
Care must be taken when squeezing the pipet bulb on the filter pipet. Too much pressure might cause the filter to leak or fall off. Add about 2 mL of fresh tert-butyl methyl ether to the solid in the RB flask, warm briefly, let the solids settle for a minute, and pipet the liquid to the centrifuge tube as before. Again allow the solids to settle briefly in the centrifuge tube, then filter the liquid through the pressure filtration apparatus, into the same 25 mL Erlenmeyer flask. Doing a rinse such as this helps to ensure that any trimyristin that was left behind in the RB flask and centrifuge tube is not lost, thereby helping to ensure that
The following mistakes were made when carrying out the experiment. What effect does each have on the calculated molar mass? Be specific. For example, too large because… Only part of the pipet was immersed in the boiling water, so the temperature in part of the pipet was less than that of the water bath. If the temperature was less than the water bath in some places because only part of the pipet was immersed in the boiling water, the molar mass calculated would become lower.
Centers for Disease Control and Prevention (CDC) study published in February 2011, showed that the babies are at risk of having certain types of congenital heart defects was 20 to 70 percent higher than it was for babies whose mothers didn't smoke. The defects included those that interrupt the flow of blood from the right side of the heart into the lungs and openings between the upper chambers of the heart. The data was collected from 2,525 babies who had a heart defect at birth and 3,435 babies who were born healthy between 1981 and 1989 in Washington, D.C. Learning disorders, behavioral problems and lower IQ’s are also all effects smoking can have on an unborn
We also found problems when we had placed clay on the tip of the pipette to seal the air out. On some of the pipettes the clay was not properly sealing the pipette causing it to leak. Suggestions for Improvement Some suggestions for improvement would include to properly place the clay correctly sealing the 5mL pipettes. Also, for the temperature recordings, the lab could of been improved by letting the burner heat up to the proper temperature and then placing the pipette into the
