Sphygmomanometer Research Paper

Decent Essays
The sphygmomanometer is used to read our blood pressure. Many of us are aware of this medical machine because we get our blood pressure checked at the doctor’s office. This is important to us because it can let us know of any heart complications such as high blood pressure, strokes, heart attacks, or kidney disease. All of these are preventable if caught in time with a doctor’s supervision and medication.

Although many of us have seen this device there is a process to using this medical machine because there are different parts to this machine. For example there is an inflatable cuff, and along with the cuff there is a bladder. There is also a release valve, a manometer, and a bulb. Aside from these instruments we also need a stethoscope.

Although today there are modern versions of this machine the concept is similar. The sphygmomanometer has an open end manometer that is used to measure the gauge pressure of the actual cuff. As we squeeze the bulb and inflate the cuff the blood flow stops, and we hear no sound in the stethoscope. The gauge should read 30 to 40 mmHg above the person 's normal BP reading. If this value is unknown you can inflate the cuff to 160 - 180 mmHg. The goal is for the cuff to reach an equilibrium, now the stethoscope kicks in and is used to listen for the blood flow at its highest point, and the lowest point. When the blood pressure is its highest is when we get the systolic blood pressure is measured. When the blood pressure is at its lowest the diastolic pressure is measured The American Heart Association recommends that the blood pressure should fall between 2 - 3 mmHg per second, anything faster is likely to result in an inaccurate measurement. When pressing the bulb this increases the pressure on the cuff. The increase pressure of the cuff restricts the artery which slows down our blood pressure. As we release the valve the blood pressure decreases. The American Heart Association recommends taking a reading with both arms so that both the readings can be averaged. Checking the pressure for accuracy we should wait about five minutes between each readings. Typically, blood pressure is higher in the mornings and lower in the

    Slowly deflate blood pressure cuff (rate of 2-3 mmHG per second) 6. Listen for the return of pulse. The reading on the sphygmomanometer at the first sound of the pulse is the systolic blood pressure. 7. Continue to deflate blood pressure cuff until you no longer hear the pulse.…

    Sublingual glyceryl trinitrate (GTN) should be administered because it is considered first line treatment for acute coronary syndromes such as myocardial ischaemia because it acts a vasodilator which dilates blood vessels, increases blood flow to the myocardium and reduces workload of the heart. 14 It is very effective in restoring blood flow and oxygen to an ischemic heart. 1 Continue to observe and monitor patient’s vital signs for adverse side effects. One spray should be administered 400microg which should be repeated at 5 minute intervals. Blood pressure should be monitored in between doses to ensure systolic blood pressure does not fall below 100mmHg.…

    As you can see from Table 1, we even had one of our daphnia specimens die from the heart rate slowing down too much, most likely. It was expected that caffeine would raise the heart rate even more than it did. Our results indicate that the heart rate only went up a very small margin of 2%. This reason was not significantly higher than its base rate could be that the daphnia was stressed from already having other chemicals given to it. It also could have been stressed from the beginning due to being squished by the petri dish cover and this would have given us a higher baseline heart rate to begin…

    After estimating the systolic pressure through palpation, I put the head of the stethoscope lightly over the brachial artery and inflated the cuff to a pressure that was 20-30mmHg above my estimated systolic pressure. I then deflated the cuff using the valve on the bulb at a steady rate. As I slowly deflated the cuff I heard the pulse return and noted the pressure when I first heard the regular beat. This…

    I would run a blood test to see how many RBC 's Mark has in order to determine whether his body would be able to survive higher altitudes. Therefore, I would have to check oxygen levels as well along with blood pH. I expect to see levels around that of an individual at sea level because he was not on the mountain long enough to make more RBC 's. Arterial oxygen I would expect to be lower than normal because of the fact he was having difficulty breathing and his body was in need of oxygen. Arterial pH (metabolic) I would expect to be low because a person with metabolic acidosis will hyperventilate due to the carotid/aortic bodies recognizing the…

    The ventricle of the heart is the main heart muscle that pumps blood. When HCM occurs the left ventricle within the heart thickens. When the thickening of the ventricle occurs there will be a decreased ventricular chamber volume, and abnormal ventricular relaxation. This deals with the diastolic aspect of the heart. Since the amount of blood pumped and ejected by the heart per minute will be decreased, the heart rate will increase.…

    There are many things you can do when your blood begins to clot, but these are one of the most common medically prescribed drugs people use. This prescribed drug is also used to thin the blood clots once it is formed. Angiotensin converting enzyme inhibitors help peoples hearts get in better conditions. ACE helps people hearts get in better conditions. ACE also helps with systolic heart failure.…

    The force applied to the heart’s walls and the pressure in the venous system is blood pressure (793). In determining blood pressure, systolic pressure appears when an artery is stretched to its maximum during contraction of the heart chambers, and diastolic pressure appears when an artery can no longer recoil during relaxation of the heart chambers (794). The top value of blood pressure is the systolic pressure, and the bottom value is the diastolic pressure (794). The reclining blood pressure is usually always lower than standing blood pressure. Light exercise can help people control their blood pressure, but lack of exercise can increase risks of developing cardiovascular disorders (“Physical Activity”).…

    The new practice is to use crystalloids minimally, only to maintain IV access and as a flush between blood products. Rather FFP, PRBC, and PLT are infused in a 1:1:1 ratio, which has shown to decrease mortality rates. The second treatment method is to maintain the circulation of the patient. Traditionally this was done by raising and maintaining the patient’s systolic blood pressure to a “normal” level. This was found to actually causing rebleeding in the patient by what has been termed “popping the clot.” That means that the normal systolic pressure disturbs the thrombi that are already formed; only increasing hemorrhage.…
