Blood Pressure Lab Report
Introduction:
Heart rate and blood pressure are key factors in determining overall physical health. Together they establish how well the cardiovascular and circulatory systems are functioning, which is important in engaging in appropriate exercise safely. It is important to know and understand the resting vitals of an individual to establish a baseline of what is within normal ranges for that individual. We take resting vitals to ensure that physical activity does not cause any undue stress that is beyond the maximum amount that the individual can endure. The heart rate is the number of times the heart beats per minute (bpm) (“Cardiac Output and Blood Pressure – PT Direct”). This number can fluctuate, meaning increase or decrease depending …show more content…
There was approximately a 71bpm difference from sitting to standing and a 22 bpm difference from standing to laying down. The changes in heart rate can be attributed to the level of activity. The heart rate can increase slightly from a resting position to a standing position, but will eventually settle. There is only a brief increase during the transition in position.
Define Mean Arterial Pressure (MAP). What is the most important factor that determines blood pressure? Why is MAP a useful measurement?
Mean arterial pressure is defined as the average pressure in the arteries during one cardiac cycle. Blood pressure is affected by cardiac output, blood viscosity- thinness or thickness of blood and total peripheral resistance (TPR)- the amount of resistance the blood encounters as it moves through the blood vessels. The total pressure can influence blood pressure due to the size of the vessels, the smaller the diameter of the vessel the higher the pressure, thus increasing blood pressure. As for blood viscosity, it is influenced by the level of hydration in the body. The more dehydrated the body is the thicker the blood is, which makes the heart work harder to pump the blood through the body resulting in increased blood pressure. Together blood viscosity and TPR are important factors in determining blood pressure. MAP is a useful measure for blood pressure because it can be used to calculate overall blood flow and delivery of nutrients to all organ systems
