Blood pressure is measured with an instrument, called as
-
Thermometer
-
Stethoscope
-
Sphygmomanometer
-
Clinical thermometer
A sphygmomanometer or blood pressure meter is a device used to measure blood pressure.
Blood pressure and heart beat is regulated by
-
Insulin
-
Adrenalin
-
Optic nerve
-
Growth hormone
Epinephrine (adrenaline) and norepinephrine (noradrenaline) is a neurotransmitter which regulates the contraction and relaxation of the heart. The effect of adrenalin is known as the fight-or-flight response. It increases the heart beat.
In a normal man, blood pressure is
-
120/80mm of Hg
-
80/100 mm of Hg
-
80/120 mm of Hg
-
100/80 mm of Hg
Blood pressure is defined as the pressure applied by the blood on the walls of arteries and veins during circulation. The instrument used is called a sphygmomanometer, and two variables are measured:
1. Systolic pressure, which occurs during heart muscle contraction, averages around 120 and is expressed in millimeters of mercury (mm Hg).
2. Diastolic pressure, which occurs during relaxation of the heart muscle, averages around 80 mm Hg.
Sphygmomanometer measures
-
Blood pressure
-
Pulse rate
-
Rate of heart beat
-
All of the above
Blood pressure is the pressure exerted by the flowing blood on the elastic walls of arteries. Blood pressure is measured in two stages- systolic and diastolic. The instrument by which we can measure blood pressure is called sphygmomanometer. In humans, the blood pressure is measured in the brachial artery.
Systolic pressure is higher than diastolic pressure due to
-
Volume of blood in the heart is greater during systole
-
Arteries contract during systole
-
Blood vessels offer resistance to flowing blood during systole
-
Blood is forced into arteries during systole
Blood pressure is the pressure applied on the arteries and veins during the circulation. The instrument used is called a sphygmomanometer and two variables are measured as follows
1. Systolic pressure, which occurs during heart muscle contraction which forces blood into arteries, averages around 120mmHg and is expressed in millimeters of mercury (mm Hg).
2. Diastolic pressure, which occurs during relaxation of the heart muscle, averages around 80 mm Hg.
The value of diastolic blood pressure is
-
120 mm Hg
-
80 mm Hg
-
120/80 mg Hg
-
40 mg Hg
Hypertension is the term for blood pressure that is higher than normal (120/80). In this measurement, 120 mm Hg (millimeters of mercury pressure) is the systolic, or pumping pressure and 80 mm Hg is the diastolic, or resting, pressure.
