This is impossible. Systolic pressure is the pressure in the artery during the heart contractions. Diastolic pressure is during heart relaxation. Picture this, and you'd see that it's impossible to have diastolic pressure equal or greater than systolic pressure.

How do you calculate pulse pressure?
PP= SP - DS Pulse Pressure is equal to Systolic Blood Pressure minus Diastolic Blood Pressure.
What is good systolic pressure?
The systolic pressure is always stated first and the diastolic pressure second. For example: 122/76 (122 over 76); systolic = 122, diastolic = 76. Blood pressure of less than 140 over 90 is considered a normal reading for adults. A systolic pressure of 130 to 139 or a diastolic pressure of 85 to 89 needs to be watched carefully. A blood pressure reading equal to or greater than 140 (systolic) over 90 (diastolic) is considered elevated (high).
Instrument which detects the instant at which the external pressure is equal to the systolic pressure?
Manometer
Is diastolic pressure equal to heart rate?
Systolic blood pressure is when the left ventricle contracts (first number), diastolic pressure is when the left ventricle relaxes (second number).
Is the mean arterial pressure equal to the average of systolic pressure and diastolic pressure?
Mean Arterial Pressure (MAP) is the mean of pressure you would obtain if you took measurements in several intervals during the cardiac cycle. Ex. systolic pressure + 2x Diastolic pressure/3 120/80= 120 + 2(80)/3= 93mmHG ( approximately)
What does it mean if you have high blood pressure?
There are many reasons one could have high blood pressure. Being overweight, and kidney disease are just two explanations. It is best to consult your doctor. Chronic high blood pressure is known as the silent killer because if it isn't treated it can lead to all sorts of problems like heart disease. Well it mean that when your heart pump the blood it's putting too much pressure through the arteries than it normally is. which is bad for your body.
What is the ideal blood pressure for 25 year old female?
Normal blood pressure for an adult is below 120 (systolic) and below 80 diastolic. The blood pressure is usually quoted as (for example) "120 over 80" or 120/80. What this means is that the maximum pressure which your blood should be when your heart contracts (systolic pressure) is 120 mm Hg (millimeters of mercury); the maximum diastolic pressure (when your heart relaxes) is 80 mm Hg. The National Institutes of Health in the USA recommend seeking medical advice if your blood pressure, especially the systolic pressure, is higher than this. You can also help to reduce your blood pressure by stopping smoking, reducing alcohol intake, losing weight, taking more exercise and cutting down on salty food.

How do you take a blood pressurer?
Blood pressure is an expression of the strength of arterial circulation in a human or animal. To measure the flow, one uses a pressure meter or 'sphygmomanometer', comprising an inflatable cuff to restrict blood flow, and a mercury or electronic manometer to measure the pressure.The pressure is stated as two numbers, the highest pressure that blood reaches (pushes past the cuff) and the lowest (the flow is unimpeded and flows without being pushed by the heart contraction). The higher pressure is the systolic (heart pushing), the lower the diastolic. Blood pressure is stated as both of these numbers, e.g. 115/75 spoken "115 over 75" is a systolic pressure of 115 (mm Hg), a diastolic of 75 (mm Hg).*For SI conversion, the mm of mercury, also known as the Torr (for Evangelista Torricelli), is equal to approximately 133.3 Pascals.BP can be measured using palpation in emergency situations. This only gives a rough estimate of systolic pressure. It can be used with the carotid, the femoral, or radial pulse.Normally, manual sphygmomanometers are used in conjunction with a stethoscope to determine the two pressures. You use a BP cuff, pump it up until the pressure in the cuff is 20 mm Hg above the pressure in the artery. Using a stethoscope you can hear when this happens. No sound is heard in the artery.Then the pressure is released and when the pressure is heard again the second reading is made.Another method of measurement is invasive, intra arterial pressure monitoring. This is where an arterial line is inserted into an artery and taped into place, with a bag of pressurised fluid preventing the backflow of blood from the artery (as it is under a lot of pressure in an artery). The line is used to sample arterial blood flow to measure dissolved gases in it and measure arterial blood pressures continuously.
Can someone provide comprehensive, step-by-step assistance for my Statistics homework on Quantitative methods I'm specifically seeking a solution that will help me understand the concepts better. Thank you in advance?
Of course! I'd be happy to help you with your Statistics homework and provide a step-by-step solution to enhance your understanding of the concepts. Here is the sample question with the solution. Question: A pharmaceutical company is conducting a study to evaluate the effectiveness of a new drug in reducing blood pressure. The company randomly selects 100 patients with hypertension and divides them into two groups: a treatment group receiving the new drug and a control group receiving a placebo. After 12 weeks, the systolic blood pressure measurements (mmHg) for each patient are recorded. The data collected for the treatment group are as follows: Treatment Group (new drug): Mean systolic blood pressure = 128 Standard deviation = 10 The data collected for the control group (placebo) are as follows: Control Group (placebo): Mean systolic blood pressure = 136 Standard deviation = 12 Using appropriate statistical techniques, determine whether there is a significant difference in the mean systolic blood pressure between the treatment and control groups. Assume a significance level of 0.05. Solution: To determine whether there is a significant difference in the mean systolic blood pressure between the treatment and control groups, we can perform an independent samples t-test. Step 1: State the hypotheses: Null hypothesis (H0): The mean systolic blood pressure in the treatment group is equal to the mean systolic blood pressure in the control group. Alternative hypothesis (Ha): The mean systolic blood pressure in the treatment group is not equal to the mean systolic blood pressure in the control group. Step 2: Set the significance level: The significance level (α) is given as 0.05. Step 3: Compute the test statistic: We can use the two-sample independent t-test formula to calculate the test statistic: t = (mean1 - mean2) / sqrt[(s1^2 / n1) + (s2^2 / n2)] where: mean1 = mean systolic blood pressure in the treatment group mean2 = mean systolic blood pressure in the control group s1 = standard deviation of systolic blood pressure in the treatment group s2 = standard deviation of systolic blood pressure in the control group n1 = sample size of the treatment group n2 = sample size of the control group Plugging in the given values, we have: mean1 = 128, mean2 = 136, s1 = 10, s2 = 12, n1 = 100, n2 = 100 t = (128 - 136) / sqrt[(10^2 / 100) + (12^2 / 100)] = -8 / sqrt[1 + 1.44] = -8 / sqrt(2.44) ≈ -8 / 1.56 ≈ -5.13 Step 4: Determine the critical value: Since the test is a two-tailed test and the significance level is 0.05, we need to find the critical value corresponding to a significance level of 0.025 in each tail. From the t-distribution table or statistical software, the critical value for a two-tailed test with a degree of freedom (df) of 198 (n1 + n2 - 2) is approximately ±1.972. Step 5: Make a decision: Since the absolute value of the test statistic (-5.13) is greater than the critical value (1.972), we reject the null hypothesis. Step 6: State the conclusion: There is sufficient evidence to conclude that there is a significant difference in the mean systolic blood pressure between the treatment and control groups (p < 0.05). The new drug appears to have a significant effect on reducing blood pressure compared to the placebo.

Is 124 over 70 good blood pressure for an 18 year old female?
The ideal blood pressure would be 120/80 or below (note: not too low) taken under ideal conditions (ie sitting quietly for a few minutes, no caffeine, no undue anxiety or stress). An individual is not considered to be hypertensive until they reach equal or above 140 systolic OR equal or above 90 diastolic OR they're taking medication for hypertension.
Is blood pressure of 103 over 66 low for a 65 year old woman?
Usually, as people advance in years, their aorta becomes atheromatous thus making it very rigid. This increases the peripheral vascular resistance (the resistance exerted to the blood flow coming out of the aorta) thus increasing the systolic blood pressure. Blood pressure is equal to cardiac output times the peripheral vascular resistance. But the lower the blood pressure to sustain hemodynamic stability in an individual (without any symptoms), the better. So the blood pressure mentioned here (90/51 mmhg) is actually beneficial to a 63 year old and the heart is less stressed supplying the metabolic needs of the body without any symptoms.
