Question

4. Summary (4-5 paragraphs) Explain your data by using information you introduced in your introduction. Make sure to demonstrate you understand the underlying physiology explaining why blood pressure changes in response to changes in body position. Refer to your table and graph and point out any important data. If your results did not match your expected results, write a paragraph suggesting one reason your results might have been different from the expected results.

Answer 1

Why blood pressure changes in respond to changes in body position

Science has been proved that the poor posture can raise the blood pressure.This is actually a neurological link between poor posture and increased bllod pressure.As the posture comes forward this puts more pressure on heart and lungs.

Blood pressure is commonly meassured in a seated or supine position,how ever the two positions gives different measssurement values.With that in mind,any time the value is recorded.It is widely accepted that diastolic pressure while sitting position are higher than when the patient is in supine position by as much as 5mmHg.When the patient is lying in supine position the blood pressure drops.

When the arm is at the level of the heart,the systolic pressure can be 8mm higher than such as when the patient is in supine position rather than siting.A patient supporting their own arm may increase the pressure reading.It the patient's back is not supported (ie, when the patient is seating on the examination table instead of a chair) the diastolic pressure may be increased by 6mmHg.

Crossing the legs also may raise the systolic pressureby 2-8 mmHg.Arm position play a dramatic role in the value errors as well.If the arm is below level of the heart,values will be too high,if the arm is above the level of the heart,values will be under estimated.For every inch the arm is above or below the level of the heart a 2mmHg difference will be found.
