1. Auscultation method is more accurate by using the stethoscope to listen for systolic blood pressure compared to palpation of systolic blood pressure at wrist. It is easier to listen for the ‘tap’ during the systolic pressure rather than palpating for it, as the systolic pressure may not be palpated if it is a weak pulse.

2. Systolic pressure:
• Pressure in the arteries when the blood is being pumped out of the heart into the arteries
• The maximum blood pressure, when the ventricles are in contracting phase
Diastolic pressure:
• Pressure in the arteries when the blood is flowing away from the arteries into the other blood vessels
• The minimum blood pressure, when the heart is relaxed
Pulse pressure:
• Difference between the systolic pressure and diastolic pressure
• The amount of force produced for a contraction of the heart to occur

Arm is raised:
• More gravitational force exerted on the raised arm, hence the blood has to use more force to restrain against the greater pressure in the arm. Also, the blood entering the raised arm has to flow into the arm against more pressure exerted due to gravity. The blood pressure in the arm will be reduced more than if the arm is at the heart level.

Arm is lowered
• Less gravitational force in the lowered arm since it is closer to the ground, hence less force from the blood needed to restrain against the lowered pressure in arm. Therefore the loss of blood pressure would be reduced, generating a greater blood pressure.…
