's general knowledge that blood pressure will fluctuate in one day
The level of blood pressure is not merely closely related to heart function, blood vessel resistance and blood capacity, the influence of the factor that and receive the nerve, humoral,etc., age, season, climate and professional difference, blood pressure values will be different to some extent too, movement, has a meal, mood changing, stool, ***,etc. cause rising of blood pressure,but rest, sleep can be made blood pressure not dropped.

General normal people's daily blood pressure fluctuation is in 2. 7- 4. 0 kPas (20- 30 millimetres of mercury columns) In the range, the sleep can cause blood pressure to drop by about (women 20% more obvious under the influence of there is not depressoring) ,The blood pressure peak is generally from 9- 10 o'clock and 4 o'clock in the afternoon a.m. to 8 p.m., the blood pressure minimum is at 1- 3 o'clock at mid-night, sleep time phase drop on B and 1v time phase often at this moment. The old hypertension patient is relatively long in blood pressure peak and minimum duration, form the platform.

Spirit stimulate, such as can often cause the obvious rising of systolic pressure excited, frightened the intersection of mood and change, movement can also make systolic pressure increase obviously, especially move, make systolic pressure rise Damien 24 often vigorously. 0- 26. 7 kPas (180- 200 millimetres of mercury columns) ,Blood pressure can drop after the movement stops. Ambient temperature rise, can make diastolic pressure reduce such as wash warm water bath,etc., and temperature reduce until winter wash cold bath,etc., can enable systolic pressure rise.

There can be three kinds of types in the situation of blood pressure fluctuation: Split-blip type (the great majority) , similar to the split-blipping type (minority) With the unimodal type (a few) .

The mechanism of blood pressure fluctuation may be to relate to diurnal law that the organism biological clock control, because this law can influence the humoral activity of nerve, make the rhythm change take place in noradrenaline of blood, blood pressure and heart rate,etc., it may relate to the fact that the tension is reduced at the night of sympathetic nerve too that blood pressure drops at night. The normal, the fluctuating range of blood pressure does not have a unified standard yet at present in the daytime and night. One abroad finds to the results of study of 3304 people, the normal, dynamic blood pressure fluctuates in 15 on average in 24 hours. 3- 16. 0/ 9. 3- 10. 0 kPa ( 115- 120/ 70- 75One millimetre of mercury columns) In the range, blood pressure mean value in daytime is 16. 0- 16. 6/ 9. 3- 10. 0 kPa ( 120- 125/ 70- 75One millimetre of mercury columns) During, the blood pressure mean value of night is in 14. O one 14. 7/ 8. O one 8. 7 kPa ( 105- 110/ 60- 65One millimetre of mercury columns) During. If is the normal with a standard deviation range of soil of average, the fluctuating range of average dynamic blood pressure is 12 in 24 hours. 9- 18. 1/ 7. 7- 11. 7 kPa ( 97- 136/ 58- 88One millimetre of mercury columns) ,Daytime is 13. 3- 18. 9/ 8. 0- 12. 0 kPa ( 100- 142/ 60- 90One millimetre of mercury columns) ,It is 11 at night. 5- 16. 5/ 6. 7- 10. 7 kPa ( 86- 124/ 50- 80One millimetre of mercury columns) . So if the average of 24-hour blood pressure is in 18. 2/ 11. 9 kPas (mercury column of 137/ 89 millimetres) The above, the blood pressure value is in 18 in the daytime. 9/ 12. 1 kPa (mercury column of 142/ 91 millimetres) The above, the blood pressure value exceeds 16 at night. 0/ 10. 7 kPas (mercury column of 120/ 80 millimetres) ,It is generally acknowledged it is probably hypertension.
