What does mmHg mean?
Medical Definition of mm Hg : a unit of pressure equal to the pressure exerted by a column of mercury 1 millimeter high at 0°C and under the acceleration of gravity and nearly equivalent to 1 torr (about 133.3 pascals) The pulse was 110 beats per minute and the blood pressure was 105/60 mm Hg …—
What is the meaning of mmHg in BP?
Blood pressure is measured in millimetres of mercury (mmHg) and is given as 2 figures: systolic pressure – the pressure when your heart pushes blood out. diastolic pressure – the pressure when your heart rests between beats.
Why do doctors use mmHg?
As mercury is so much denser than water or blood, even very elevated blood pressures result in it rising no more than about a foot. This quirk of medical history gives us the modern measurement unit for blood pressure: millimetres of mercury (mmHg).
What is normal mmHg?
A healthy blood pressure reading should be lower than 120/80 mmHg. Normal blood pressure is less than 120 mmHg systolic and 80 mmHg diastolic (see blood pressure chart below), and may vary from 90/60 mmHg to 120/80 mmHg in a healthy young woman. A blood pressure of 140/90 mmHg or higher indicates high blood pressure.
How do you get mmHg?
As discussed earlier we know that one millimetre of mercury is the pressure exerted by a 1mm vertical column of mercury at 0 degree Celsius. And we also know that one mmHg is also equal to 1 torr, which is 1 / 760 of atmospheric pressure (atm) that is 1 atm = 760 mmHg.
What does the 120 mmHg reading indicate?
What is high blood pressure (hypertension)?
| Blood Pressure Levels | |
|---|---|
| Normal | systolic: less than 120 mm Hg diastolic: less than 80 mm Hg |
| At Risk (prehypertension) | systolic: 120–139 mm Hg diastolic: 80–89 mm Hg |
| High Blood Pressure (hypertension) | systolic: 140 mm Hg or higher diastolic: 90 mm Hg or higher |
Is blood pressure kPa or mmHg?
Normal resting blood pressure in an adult is approximately 120 millimetres of mercury (16 kPa) systolic, and 80 millimetres of mercury (11 kPa) diastolic, abbreviated “120/80 mmHg”. Blood pressure (BP) is the pressure of circulating blood on the walls of blood vessels.
What is normal blood pressure age 50?
Normal Blood Pressure By Age
| Age | SBP | DBP |
|---|---|---|
| 46-50 | 119.5 | 80.5 |
| 51-55 | 125.5 | 80.5 |
| 56-60 | 129.5 | 79.5 |
| 61-65 | 143.5 | 76.5 |
How do you convert blood pressure to mmHg?
Using the values for each in SI pressure units, any pressure in kilopascals can be converted to millimetre of mercury units using the conversion factor below:
- 1 mmHg = 133.322 Pascals (Pa)
- 1 kPa = 1000 Pascals (Pa)
- mmHg value x 133.322 Pa = kPa value x 1000 Pa.
- mmHg value = kPa value x 7.50062.
Is mmHg pressure or volume?
A barometer measures gas pressure by the height of the column of mercury. One unit of gas pressure is the millimeter of mercury (mmHg). An equivalent unit to the mmHg is called the torr, in honor of the inventor of the barometer, Evangelista Torricelli. The pascal (Pa) is the standard unit of pressure.
What does mm Hg stand for?
A Manometric Unit of Pressure mmHg stands for millimeters of mercury. mmHg is a manometric unit of pressure, which is almost identical to 1 Torr. In SI units, 1 mmgH = 133.3 Pa.
How many mm in Hg?
›› Quick conversion chart of in Hg to mm Hg. 1 in Hg to mm Hg = 25.4 mm Hg. 2 in Hg to mm Hg = 50.80001 mm Hg. 3 in Hg to mm Hg = 76.20001 mm Hg. 4 in Hg to mm Hg = 101.60001 mm Hg. 5 in Hg to mm Hg = 127.00001 mm Hg. 6 in Hg to mm Hg = 152.40002 mm Hg.
How do you convert mm Hg to Psi?
The easiest way is to use the standard 1 atmosphere as a conversion factor. 760 mm Hg = 1 atm. 14.7 psi = 1 atm. Therefore, 760 mm Hg = 14.7 psi. Dividing both sides of the equation by 760, you get 1 mm Hg = 0.019 psi.
What is the pressure of mm Hg?
One mmHg is the pressure exerted by a 1 mm vertical column of mercury (Hg) at 0 degree Celsius. One mmHg is virtually equal to 1 torr, which is defined as 1/760 of 1 atmosphere (atm) pressure (i.e., 1 atm = 760 mmHg).
