The arterial blood pressure generated by the heart in a patient who is standing upright is 140 mmHg.
What is the hydrostatic pressure at all locations within the arterial circulation?
Since the patient is standing all arteries at heart level will have a hydrostatic pressure of 0 mmHg.

-Below heart level will be positive and range from about 50 mmHg at the waist to about 100 mmHg at the ankle.
-Above heart level will be negative
The arterial blood pressure generated by the heart in a patient who is standing upright is 140 mmHg.
What is the arterial pressure measured in the toe of the upright patient?
240 mmHg.
The toe is far below heart level, hydrostatic pressure is 100 mmHg.
100 mmHg+140 mmHg=240 mmHg
The arterial blood pressure generated by the heart in a patient who is standing upright is 140 mmHg.
What is the arterial pressure measured at this patient knee?
215 mmHg.
The knee is somewhat below heart level, the hydrostatic pressure is 75 mmHg.
75 mmHg+140 mmHg= 215 mmHg
The arterial blood pressure generated by the heart in a patient who is standing upright is 140 mmHg.
What is the arterial pressure measured at the standing patient's waist?
190 mmHG
The waist is slightly below heart level the hydrostatic pressure is in the range of 50 mmHg.
140 mmHg+50 mmHg= 190 mmHg
The arterial blood pressure generated by the heart in a patient who is standing upright is 140 mmHg.
What is the arterial pressure measured at the standing patient's upper arm?
140 mmHg.
The upper are is at heart level the hydrostatic pressure is 0 mmHg.
0 mmHg+140 mmHg= 140 mmHg
The arterial blood pressure generated by the heart in a patient who is standing upright is 140 mmHg.
What is the arterial pressure measured at the finger when the patient full extends an arm towards the sky?
90 mmHg
The extended finger is well above heart level, the hydrostatic pressure is approximately -50 mmHg
-50 mmHg+140 mmHg= 90 mmHg
The arterial blood pressure measured in a supine patient's arm is 140 mmHg.
What is the hydrostatic pressure at all locations within the arterial circulation?
0 mmHg
All arteries are at the level of the heart, so hydrostatic pressure throughout the arterial circulation is 0 mmHg
The arterial blood pressure measured in a supine patient's arm is 140 mmHg.
What is the arterial pressure at the knee of the supine patient?
140 mmHg
The arterial blood pressure measured in a supine patient's arm is 140 mmHg.
What is the arterial pressure in the carotid artery of the neck of the supine patient?
140 mmHg
Normally, what happens to venous flow in the legs during inspiration?
Decreases
All the following occur during expiration except: A.) Venous return to the heart decreases B.) Venous flow in the legs increases C.) Abdominal pressure increases D.) The diaphragm rises into the thoracic cavityC.) Abdominal pressure increases
