Blood pressure is measured by mercury manometer and a stethoscope by wrapping a closed air-filled jacket around the upper arm of a person at the level of the heart. The systolic pressure (the maximum pressure when the heart is pumping) and the diastolic pressure (the minimum pressure when the heart is resting) of a healthy person are indicated as 120/80 respectively. These values are expressed in:

The systolic pressure (the maximum pressure when the heart is pumping) and the diastolic pressure (the minimum pressure when the heart is resting) of a healthy person are indicated as 120/80 respectively. These values are expressed in: Correct Answer mmHg

Explanation:

The Blood pressure of a normal healthy person is 120/80 mmHg.

So, the value of blood pressure are measured in mm of mercury.

Additional Information

Various unit for measurement of flow are:

 1 pascal → 1 N/m2

1 kg/m2 → 9.807 N/m2 or 1 Pascal

1 kPa → 0.01 kg/cm2

1 Standard atmospheric pressure → 1.02 kg/cm2 = 1.013 bar = 760 mm of Hg = 10.33 m water head

The figures show the cross-section of an oil pipe with a manometer attached. On the right side of the manometer, the manometer fluid is in contact with oil, and on the left side, the manometer is open to the atmosphere. The oil has a specific gravity of 0.85 and the manometer fluid has a specific gravity of 1.5. What is the gauge pressure at the center of the pipe if hm is 10 cm and ho is 5 cm?
A mercury (specific gravity = 13.6) manometer connected across an orificemeter fitted in a pipe shows a manometer reading of 2 cms. If the manometer liquid is changed to carbon tetrachloride (specific gravity = 1.6), then for the same flow rate of water the new manometer reading will be __________ cms.
Pressure difference between two points in vessels, pipelines or in two different pipelines can be measured by a differential manometer. The pressure difference measured as the mm of water coloumn in case of mercury-water, differential manometer is equal to (where, H = difference in height of mercury column in mm).
A Differential manometer is connected at the points A and Bat the centre of two pipes. The pipe A(left limb) contains a liquid of specific gravity = 1.5 while pipe B (right limb)contains a liquid of specific gravity 0.85. The pressure at A and B are .5 kgf/cm2 and 1.2 kgf/cm2 respectively. Find the difference in level of mercuru in the differential manometer. A is 2.5m above B and 5 m above the mercury in its own limb. B is 2.5 m above the mercury level in limb A.
The mixing vat in a factory receives liquid ingredients through six separate value--- labeled R.S.T.U,Y and Z -- each of which has exactly two settings: open and closed.The mixing vat operator must ensure that each valve is set open or closed according to the following conditions: If T is open, both S and Z must be closed, R and Z cannot both be closed at the same time; If Y is closed, Z must also be closed;S and U cannot both be open at the same time. If the maximum number of valves that can be closed at the same time are closed which of the following must true?
In a U tube manometer filled with mercury and measuring the pressure of air in a container, the difference in height of the two columns is 12 cm. If the specific weight of mercury is 13.6 kg/liter, then what is the pressure measured by the manometer? (g = 10 m/sec2)
The fasting blood sugar level (F) and the post prandial blood sugar level (PP) of a patient was monitored for four weeks W1, W2, W3, W4, and the readings (in mg/dl) for the four weeks are as follows: F/PP: 170/220, 150/180, 120/150, 90/120. These have been presented through a bar graph. The normal range is considered to be: F/PP: 70-100/100-130   During which week was the fasting blood sugar level of the patient approximately 115.4% above the upper limit of normal PP blood sugar level?
