Determination of Blood Pressure and Lung Function
Discuss the role of arterial blood pressure in human physiology, the importance of measuring it and the main factors influencing it.
Calculate the mean 0 standard deviation for the Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) measured by the sphygmomanometer and the electronic blood pressure meter. Use statistical analysis to compare SBP and DBP measured by the two different types of equipment. Discuss the role of standard deviation in reflecting repeatability of the measurement.
Did blood pressure and pulse rate change when the body positions changed? Give appropriate physiological explanations accounting for these effects.
How did exercise influence blood pressure? What is the explanation for this?
Use the group data collected and relevant statistical analysis to find out if there is correlation between Mean Arterial Pressure (MAP) and Body Mass Index (BMI). Present MAP and BMI in a scatter plot. Discuss your findings.
Has the caffeinated beverage affected the MAP of the study group? Provide a physiological explanation of the observed findings.
Discuss the gas exchange taking place during external and internal respiration. Compare the events associated with quiet and forceful breathing.
Explain the purpose of measuring Peak Expiratory Flow (PEF) rate and use statistical analysis to compare your PEF measured by peak flow meter and spirometer.
How did PEF change in the four different body positions? Provide physiological explanations for the observed findings.
Use statistical analysis to compare Forced Vital Capacity (FVC) in short and tall subjects of your study group. Present your data in a bar chart. Explain physiologically the potential differences of the two groups.
Calculate the minute ventilation at rest and after exercising. Describe the physiological background of the observed changes.
Which exercise group (light or moderate) showed the greatest change in oxygen saturation level from resting level? Explain your observations.
How long did it take for each group to return to resting oxygen saturation levels? Discuss the events associated with post-exercise oxygen consumption.
