Respiratory variations in blood pressure.
A study of respiratory blood pressure variations in normal subjects suggests that variations in both cardiac output and peripheral resistance are involved, the latter mechanism being essentially similar to that producing the Traube waves in apnea. The interactions of the two mechanisms are compared to the known behavior of coupled electronic oscillators. T HE FLUCTUATION of the arterial pressur...
متن کاملSeasonal variations in nocturnal changes in blood pressure between Ireland and Singapore.
BACKGROUND Normal blood pressure (BP) follows a circadian rhythm, with dipping of BP at night. However, knowledge is limited in how the nocturnal dipping in hypertensive patients changes with the seasons. The study aims to examine the pattern of seasonal changes of nocturnal dip in an Irish population and furthermore, to compare it to the pattern observed near the equator where such seasonal va...
متن کاملSeasonal variation in arterial blood pressure.
Blood pressure measurements recorded during the medical Research Council's treatment trial for mild hypertension have been analysed according to the calendar month in which the readings were made. For each age, sex, and treatment group systolic and diastolic pressures were higher in winter than in summer. The seasonal variation in blood pressure was greater in older than in younger subjects and...
متن کاملSeasonal variations of blood pressure in adults: Tehran lipid and glucose study.
There is no comprehensive report on seasonal variations in individuals' blood pressure (BP) in Iranian subjects. The aim of this study is to evaluate individuals' BP during the four seasons of the year in a large number of adults in Tehran. In a population-based study in Tehran, over a period of ten years (from 1998 to 2011) during the follow up of the four phases of the TLGS, data from a total...
متن کاملDiurnal variations of blood pressure in cats.
Blood pressure (BP) was analyzed invasively using the telemetry system in unanesthetized, unrestrained healthy adult mongrel cats. After surgical implantation of a telemetry transmitter, BP was transiently elevated due to the invasive nature of the surgery, but it was gradually decreased. BP was largely stabilized seven to ten days postsurgery. Once BP was settled, systolic, diastolic and mean ...
