Here is information on a patient:

heart rate = 70 beats per minute

blood pressure 150/90

end-diastolic volume = 125 mL

stroke volume = 75 mL

Please answer the following questions:

A. What is the peak ventricular pressure? (must include units)

B. What is the pressure to open the aortic semilunar valve? (must include units)

C. What is this person's cardiac output? (must include units)

D. What is this person's end-systolic volume? (must include units)

Thank you for the help!

B. Pressure to open aortic semilunar valve. When the left ventricular pressure exceeds the aortic pressure, there will be opening of the aortic semilunar valve. Such that left ventricle flows into the aorta and increases its pressure due to the immediately due to peripheral resistance shown by the aortic wall.

Therefore, the pressure needed to open the aortic semilunar valve is equal to or greater than 120 mmHg.

Measure heart rate in beats per minute, respiration rate in breaths per minute and blood pressure as systolic/diastolic (these measurements should look like 120/70). Your pulse rate should be measured for at least 15 seconds and your respiration rate should be measured for at least 30 seconds. Try taking your blood pressure as quickly as you can. Perform the following experiments and enter your data on the Report Page. 1. While you are resting, either or sitting or lying down,...

It is generally accepted that the mean heart rate (beats per minute; bpm) of an adult human is between 65 bpm and 75 bpm, with a single average value of 72 bpm. In this case study you will test the hypothesis that the average heart rate of adults is 72 bpm (μ = 72 bpm) for all adults and then separately by gender. The distribution of heart rates is approximately normal. 1.Complete the hypothesis test for all adults(Males and Females)...

Among a sample of 16 people, the average heart rate was 69.0 beats per minute with a standard deviation 4.3 beats per minute. We are interested in the mean heart rate of the population. We assume that the heart rate is normally distributed, and that the population standard deviation is 4.8 beats per minute. At 95% confidence, what is the error bound?

The mean pulse rate of the entire population of adult men is 70 beats per minute. A sample of 10 adult male patients is given a new drug, and after several minutes, their mean pulse rate is measured at 75 beats per minute with a standard deviation of 8 bpm. Do I have sufficient evidence to support my claim that this drug is effective in raising the heart beat of male patients? a. State the null and alternative hypotheses using...

3. A blood pressure monitoring device records patient blood pressure (in mmHg) twice per minute. It is set to alert the doctor whenever the patient's systolic blood pressure falls below 75 mmHg. The measured signal includes some Gaussian noise: that is, at each measurement, the measured blood pressure PM equals the true blood pressure P, plus some noise. This noise has a Gaussian distribution about zero with a standard deviation equivalent to 2.8 mmHg. a. What is the probability that...
