Question

Blood pressure is normally expressed as the ratio of the systolic pressure (when the heart just ejects blood) to the diastolic pressure (when the heart is relaxed). The measurement is made at the level of the heart (usually at the middle of the upper arm), and the pressures are given in millimeters of mercury, although the units are not usually written. Normal blood pressure is typically 120/80.

1. How would you write normal systolic blood pressure if the units of pressure used were pascals? (Express your answer to three significant figures.)

2. How would you write normal diastolic blood pressure if the units of pressure used were pascals? (Express your answer to three significant figures.)

3. How would you write normal systolic blood pressure if the units of pressure used were atmospheres? (Express your answer to three significant figures.)

4. How would you write normal diastolic blood pressure if the units of pressure used were atmospheres? (Express your answer to three significant figures.)

5.. How would you write normal systolic blood pressure if the units of pressure used were pounds per square inch (lb/in², psi)? (Express your answer to three significant figures.)

6. How would you write normal diastolic blood pressure if the units of pressure used were pounds per square inch (lb/in², psi)? (Express your answer to three significant figures.)
