Question

4) For a mean arterial pressure of 90 mmHg, calculate the gauge pressure in Pa, produced by the heart. Pa Submit 5) The schematic below shows a human body cannulated (image a tube inserted to the body's vasculature) at three heights, B, F, and H. Blood would rise to the same height in each tube, similar to a column of water cannulated at three heights. The tubes can also be filled with a saline solution with a similar density to blood so that this will be a safer experiment to perform. For a typical adult, h is 1.2 m and hg is 1.6 m. Using the gauge pressure at heart height from the problem above, calculate the gauge pressure in the feet. Assume the density of whole blood is 1060 kg/m3. Express your answer to four significant digits

Explanation / Answer

Pgauge = Pabs- Patm

= 90- 760 = -670 mmHg

(Now 1 mmHg = 133.322368 pascals)

Therefore -670*133.322 = 89325.74
