This is the old fashioned way to measure blood pressure which prescious few nurses these days seem capable of. The equipment used is a sphygmomanometer (the arm strap that inflates and tells you the pressure it has inflated to) and a stethoscop (the hearing thing). The sphyg is placed around the arm above the elbow (at the same level as the heart) with the pump tubing pointing down the cephalic vein (big blue line cant miss it). The patients elbow should be bent and relaxed lying on a comfortable surface. No placing the steth at the correct place at the top of the forearm roughyl bellow where the tubing points you should hear nothing yet. Pump uo the sphyg until reasonable high (some docotrs like to use set limmits other even try to hear the sounds during this phase to kow when to stop). Once you believe the pressure is high enough to be cutting of the circulation start to let it off slowly. Eventually you will hear a "knocking" sound which is the sound of the blood managing to force its way through during systole and so giving the systolic pressure. Now keep letting the pressure of even slower until the knocking stops, this is when the blood is moving freely and so gives the diastolic pressure.
What else can I help you with?
Why is it that pressure changes are not considered the most effective method for regulating blood flow within the body?
Pressure changes are not considered the most effective method for regulating blood flow within the body because they can lead to inconsistent and unpredictable results. Other mechanisms, such as the autonomic nervous system and hormonal regulation, are more precise and can better maintain stable blood flow to meet the body's needs.
What generates blood pressure?
Blood pressure is generated by the force exerted by the heart pumping blood into the arteries and the resistance encountered by the blood flow in the arteries. The systolic pressure is the pressure when the heart contracts and pushes blood out, while the diastolic pressure is the pressure when the heart relaxes and refills with blood.
What is the name of the blood pressure measuered when the ventricles relax?
The blood pressure measured when the ventricles relax is called diastolic blood pressure. It is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between contractions.
What is blood pressure used to evaluate?
Your systole and diastole (or systolic and diastolic pressure). Systolic pressure is the pressure your blood exerts on blood vessels when your heart pumps out blood while diastolic pressure is the pressure your blood exerts on blood vessels when your heart is at rest(in between pumps). Blood pressure is stated as systolic pressure/diastolic pressure. The normal BP is 120/80 mmHg.
How does vasoconstriction impact blood pressure?
Vasoconstriction is the narrowing of blood vessels, which can increase blood pressure by making it harder for blood to flow through the vessels. This can lead to higher blood pressure levels.
Why the auscultatory method is called indirect?
The auscultatory method is called indirect cause it indirectly measures the arterial blood .
What is the name of the instrument used to compress the artery and record pressures in the auscultatory method of determining blood pressure?
Sphygmomanometer.
Why it is important to measure systolic pressure palpatory method before auscultatory method?
Measuring systolic pressure using the palpatory method before the auscultatory method is important because it helps to identify the approximate systolic pressure and eliminates the guesswork involved in determining when to start auscultation. This technique prevents discomfort for the patient by avoiding excessive inflation of the cuff and ensures accurate readings by helping to avoid missing the actual systolic pressure. Additionally, it can be particularly useful in cases where auscultatory sounds are difficult to detect, such as in patients with low blood pressure or those with certain medical conditions.
What is auscultatory gay?
I think you meant auscultatory *gap*. Anyway it is a range of pressure where the korotcoff sounds fade away and reappear at a lower pressure when someone is listening to a patient's blood pressure. http://en.wikipedia.org/wiki/Auscultatory_gap
How can you tell if a patient might have auscultatory gab?
An auscultatory gap can be suspected if there is a significant difference between the systolic blood pressure readings when measured by palpation and auscultation. It often occurs in patients with hypertension or atherosclerosis and is characterized by a temporary absence of Korotkoff sounds during the deflation of the cuff. If a clinician detects a drop in sound after an initial systolic reading, followed by a reappearance of sounds at a lower pressure, this may indicate an auscultatory gap. Additionally, discrepancies in blood pressure measurements from different positions can also suggest the presence of an auscultatory gap.
What isAuscultatory gap?
An auscultatory gap is a temporary disappearance of sounds during the measurement of blood pressure, typically occurring between the systolic and diastolic phases. It can lead to inaccurate readings if not recognized, as it may cause the clinician to underestimate the systolic pressure or overestimate the diastolic pressure. This phenomenon is often associated with conditions like hypertension and arterial stiffness. Recognizing an auscultatory gap is crucial for accurate blood pressure assessment.
What actions can you do to avoid an auscultatory gap?
To avoid an auscultatory gap, ensure that the blood pressure cuff is properly sized and positioned on the arm. Inflate the cuff sufficiently to exceed the systolic pressure, ideally by around 20-30 mmHg above the expected level. Additionally, palpate the radial pulse beforehand to estimate systolic pressure, and deflate the cuff slowly while listening carefully for the Korotkoff sounds, as this can help prevent missing the sounds due to an auscultatory gap. Finally, consider repeating the measurement if you suspect an auscultatory gap may have occurred.
What causes ausculatory gap?
An auscultatory gap is caused by a temporary loss of sound when measuring blood pressure, typically occurring between the systolic and diastolic pressures. This phenomenon can occur due to factors like arterial stiffness or plaque buildup, which can lead to an inconsistency in blood flow. It may also be influenced by the technique used during measurement, particularly if the cuff is inflated too high or released too slowly. Auscultatory gaps can lead to inaccuracies in blood pressure readings if not recognized.
Why are stethoscopes used during blood pressure measurement?
The auscultatory method of blood pressure measurement employs a stethoscope (for listening) and a sphygmomanometer (measures pressure). The sphygmomanometer is a mercury or aneroid manometer attached to an inflatable cuff. The cuff is fitted to the upper arm, at the same height as the heart, then inflated until the brachial artery is pressed shut. The examiner listens to the sounds of the artery at the elbow with the stethoscope, first for quiet (no flow), then, as the pressure in the cuff is slowly released, for the "whooshing" of pent-up blood starting to flow again. The pressure at which this sound is heard is systolic BP (peak pressure). Cuff pressure is continuously lowered until the artery again makes no sound, which marks diastolic BP.
How is hypertension diagnosed?
The word hypertension means high or elevated blood pressure. The method of determination would be to take a resting blood pressure. The best method would be to take the blood pressure measurement everyday at the same time of the day and trend the progress.
Why is it not possible to obtain diastolic blood pressure using the palpatory method?
The palpatory method of obtaining a blood pressure is when the person taking the blood pressure feels the radial pulse (in the wrist) while pumping up the blood pressure cuff. When the radial pulse disappears, this is the systolic blood pressure. The systolic blood pressure is the pressure exerted in the arteries when the heart has contracted and is forcing the blood through the arteries - it therefore gives the reading for the maximum blood pressure. When we feel a pulse, we are feeling the blood being forced through the arteries (meaning we only feel the pulse at the maximum pressure which is the same as the systolic blood pressure, allowing us to get a systolic blood pressure from feeling the pulse). The diastolic blood pressure is the pressure in the arteries when the heart is relaxed, or the minimum amount of pressure. Because the pressure is lower at this stage, it is not possible to feel the pulse and therefore it is not possible to obtain a diastolic reading using the palpatory method, a stethoscope is required to be able to hear the blood flow rather than feel it.
What is the best method in taking the blood pressure of newborn?
Blood pressure in newborns is not a good indicator of health. Taking blood pressure of a newborn is usually not done unless there is an underlying issue (i.e. cardiac issues). Blood pressure is usually taken using the thigh.
