Blood Pressure Determination: Techniques for measuring blood pressure.Blood Pressure: PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.Pressure: A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Hypertension: Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.Blood Pressure Monitoring, Ambulatory: Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.Heart Rate: The number of times the HEART VENTRICLES contract per unit of time, usually per minute.Antihypertensive Agents: Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS.Hydrostatic Pressure: The pressure due to the weight of fluid.Blood Pressure Monitors: Devices for continuously measuring and displaying the arterial blood pressure.Systole: Period of contraction of the HEART, especially of the HEART VENTRICLES.Hemodynamics: The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.Diastole: Post-systolic relaxation of the HEART, especially the HEART VENTRICLES.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Hypotension: Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.Intracranial Pressure: Pressure within the cranial cavity. It is influenced by brain mass, the circulatory system, CSF dynamics, and skull rigidity.Renin: A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM.

Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.Atmospheric Pressure: The pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned.Venous Pressure: The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.Sex Determination Processes: The mechanisms by which the SEX of an individual's GONADS are fixed.Air Pressure: The force per unit area that the air exerts on any surface in contact with it.

Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.Sodium Chloride, Dietary: Sodium chloride used in foods.Risk Factors: An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.Reference Values: The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality.Rats, Inbred WKY: A strain of Rattus norvegicus used as a normotensive control for the spontaneous hypertensive rats (SHR).Body Weight: The mass or quantity of heaviness of an individual.

Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.Pressoreceptors: Receptors in the vascular system, particularly the aorta and carotid sinus, which are sensitive to stretch of the vessel walls.Analysis of Variance: A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.Central Venous Pressure: The blood pressure in the central large VEINS of the body.

Phasic right coronary artery blood flow in conscious dogs with normal and elevated right ventricular pressures. (1/1429)

We studied phasic right coronary blood flow in well trained normal dogs and dogs with pulmonic stenosis. We installed electromagnetic flow transducers and pressure tubes under anesthesia to monitor right coronary blood flow, cardiac output, central aortic blood pressure, and right ventribular pressure. In normotensive dogs, systolic flow amplitude equaled early diastolic flow levels. The ratio of systolic to diastolic flow at rest was substantially greater in the right coronary bed (36+/-1.3%) than in the left circumflex bed (13+/-3.6%). Right diastolid flow runoff, including the cove late in diastole, resembled left circumflex runoff. Blood flow to the normotensive right (37+/-1.1 ml/min 100(-1) g) and the left (35+/-1.0 ml/min(-1) g) ventricular myocardium indicated equal perfusion of both cardiac walls. Throttling of systolic flow was related directly to the right ventricular systolic pressure level in the dogs with pulmonic stenosis. Retrograde systolic flow occurred in severe right ventricular hypertension. The late diastolic runoff pattern in dogs with pulmonic stenosis appeared the same as for the normotensive dogs. We obtained systolic to diastolic flow ratios of 1/3 the value of normotensive hearts in high and severe pulmonic hypertension. Electrocardiograms and studies of pathology suggested restricted blood flow to the inner layers of the right myocardium in the dogs with severe and high right ventricular hypertension. Normotensive and hypertensive peak hyperemic flow responses were similar, except for an increased magnitude of diastolic flow, with proportionately less systolic flow in hypertensive states.  (+info)

Reduction in baroreflex cardiovascular responses due to venous infusion in the rabbit. (2/1429)

We studied reflex bradycardia and depression of mean arterial blood pressure (MAP) during left aortic nerve (LAN) stimulation before and after volume infusion in the anesthetized rabbit. Step increases in mean right atrial pressure (MRAP) to 10 mm Hg did not result in a significant change in heart rate or MAP. After volume loading, responses to LAN stimulation were not as great and the degree of attenuation was propoetional to the level of increased MRAP. A change in responsiveness was observed after elevation of MRAP by only 1 mm Hg, corresponding to less than a 10% increase in average calculated blood volume. after an increase in MRAP of 10 mm Hg, peak responses were attenuated by 44% (heart rate) and 52% (MAP), and the initial slopes (rate of change) were reduced by 46% (heart rate) and 66% (MAP). Comparison of the responses after infusion with blood and dextran solutions indicated that hemodilution was an unlikely explanation for the attenuation of the reflex responses. Total arterial baroreceptor denervation (ABD) abolished the volume-related attenuation was still present following bilateral aortic nerve section or vagotomy. It thus appears that the carotid sinus responds to changes inblood volume and influences the reflex cardiovascular responses to afferent stimulation of the LAN. On the other hand, cardiopulmonary receptors subserved by vagal afferents do not appear to be involved.  (+info)

Ventricular pressure-volume curve indices change with end-diastolic pressure. (3/1429)

Many indices have been proposed to describee the diastolic pressure-volume curve mathematically and permit quantification of the elastic properties of the myocardium itself in hopes that changes in the muscle caused by disease would b.e reflected in the diastolic pressure-volume curve. To date, none of the proposed indices has been shown convincingly to discriminate one group of patients from another. While this situation in part arises from the relatively large amount of noise introduced by the technical difficulties of measuring synchronous pressures and volumes during diastole in man, ther is a more fundamental difficulty. In practice, one can measure only a short segment of the entire pressure-volume curve, and the values of all diastolic pressure-volume curve parameters investigated change significantly when one uses different segments of the same pressure-volume curve to compute them. These results were derived from relatively noise-free pressure-volume curves obtained by filling nine excised dog left ventricles at a known rate and monitoring pressure-volume curve used to compute the parameter. Merely increasing measurement fidelity will not resolve this problem, because none of these parameters accurately characterizes the entire diastolic pressure-volume curbe from a segment like that which one can reasonably expect to obtain from humans.  (+info)

'Home hypertension': exploring the inverse white coat response. (4/1429)

BACKGROUND: The classical 'white coat response' to blood pressure measurement has been studied thoroughly. However, little is known about patients showing a reverse pattern, i.e. who have lower blood pressure readings at the clinic than outside healthcare facilities. AIM: To estimate the proportion of patients whose blood pressure levels as determined by self-measurements at home are higher than those taken at the clinic and to explore possible associations with demographic, clinical, and psychological variables. METHOD: Patients consecutively attending (n = 214) an academic family medicine department in Toronto, Canada, were eligible. Subjects aged below 16 years and those on psychotropic or blood pressure-lowering agents were excluded. The clinic-home blood pressure difference (CHBPD) was calculated for each participating subject by subtracting home blood pressure from clinic blood pressure. Those who had negative values were compared with the rest of the sample. RESULTS: A considerable proportion of patients had lower blood pressure at the clinic than at home (systolic, 34.6%; diastolic, 23.8%). These subjects did not differ from the rest of the sample with regard to age, sex, levels of education attained, immigration status, body mass index, experience of current symptoms, blood pressure levels, or psychological distress. However, in patients with a 'negative CHBPD', i.e. lower blood pressure at the clinic than at home, readings taken by an automatic, self-inflating device when still at the clinic were higher than in the rest of the sample. CONCLUSION: The results point to measurement bias being at least partly responsible for higher blood pressure readings outside the clinic. Automatic measurement devices used for self/home blood pressure measurement seem to cause an alerting reaction analogous to the well-described 'white coat response'.  (+info)

Energy cost of sport rock climbing in elite performers. (5/1429)

OBJECTIVES: To assess oxygen uptake (VO2), blood lactate concentration ([La(b)]), and heart rate (HR) response during indoor and outdoor sport climbing. METHODS: Seven climbers aged 25 (SE 1) years, with a personal best ascent without preview or fall (on sight) ranging from 6b to 7a were assessed using an indoor vertical treadmill with artificial rock hand/foot holds and a discontinuous protocol with climbing velocity incremented until voluntary fatigue. On a separate occasion the subjects performed a 23.4 m outdoor rock climb graded 5c and taking 7 min 36 s (SE 33 s) to complete. Cardiorespiratory parameters were measured using a telemetry system and [La(b)] collected at rest and after climbing. RESULTS: Indoor climbing elicited a peak oxygen uptake (VO2climb-peak) and peak HR (HRpeak) of 43.8 (SE 2.2) ml/kg/min and 190 (SE 4) bpm, respectively and increased blood lactate concentration [La(b)] from 1.4 (0.1) to 10.2 (0.6) mmol/l (p < 0.05). During outdoor climbing VO2 and HR increased to about 75% and 83% of VO2climb-peak and HRpeak, respectively. [La(b)] increased from 1.3 (0.1) at rest to 4.5 mmol/l (p < 0.05) at 2 min 32 s (8 s) after completion of the climb. CONCLUSIONS: The results suggest that for elite climbers outdoor sport rock climbs of five to 10 minutes' duration and moderate difficulty require a significant portion of the VO2climb-peak. The higher HR and VO2 for outdoor climbing and the increased [La(b)] could be the result of repeated isometric contractions, particularly from the arm and forearm muscles.  (+info)

Ankle-arm index as a predictor of cardiovascular disease and mortality in the Cardiovascular Health Study. The Cardiovascular Health Study Group. (6/1429)

Peripheral arterial disease (PAD) in the legs, measured noninvasively by the ankle-arm index (AAI) is associated with clinically manifest cardiovascular disease (CVD) and its risk factors. To determine risk of total mortality, coronary heart disease, or stroke mortality and incident versus recurrent CVD associated with a low AAI, we examined the relationship of the AAI to subsequent CVD events in 5888 older adults with and without CVD. The AAI was measured in 5888 participants >/=65 years old at the baseline examination of the Cardiovascular Health Study. All participants had a detailed assessment of prevalent CVD and were contacted every 6 months for total mortality and CVD events (including CVD mortality, fatal and nonfatal myocardial infarction, congestive heart failure, angina, stroke, and hospitalized PAD). The crude mortality rate at 6 years was highest (32.3%) in those participants with prevalent CVD and a low AAI (P<0.9), and it was lowest in those with neither of these findings (8.7%, P<0.01). Similar patterns emerged from analysis of recurrent CVD and incident CVD. The risk for incident congestive heart failure (relative risk [RR]=1.61) and for total mortality (RR=1.62) in those without CVD at baseline but with a low AAI remained significantly elevated after adjustment for cardiovascular risk factors. Hospitalized PAD events occurred months to years after the AAI was measured, with an adjusted RR of 5.55 (95% CI, 3.08 to 9.98) in those at risk for incident events. A statistically significant decline in survival was seen at each 0.1 decrement in the AAI. An AAI of <0.9 is an independent risk factor for incident CVD, recurrent CVD, and mortality in this group of older adults in the Cardiovascular Health Study.  (+info)

Anthropometric, lifestyle and metabolic determinants of resting heart rate. A population study. (7/1429)

AIM: To clarify the determinants of resting heart rate at the population level in a random sample of the Belgian population. METHODS AND RESULTS: Data of 5027 men and 4150 women aged 25-74 years obtained from a Belgian nationwide survey were analysed. In multivariate analysis, blood pressure strongly correlated with heart rate in men (t = 12.4 for systolic; t = 8.8 for diastolic) and women (t = 12.0 for systolic; t = 7.7 for diastolic). Age (t = -3.4 in men; t = -8.1 in women) and height (t = -3.7 in men; t = -3.1 in women) correlated negatively with heart rate. Smoking raised heart rate in men (1-19 cigarettes.day-1, t = 6.1; > or = 20 cigarettes.day-1, t = 10.3) and women (> or = 20 cigarettes.day-1, t = 3.5). Serum phosphorus correlated negatively with heart rate (t = -3.5 in men; t = -8.3 in women). Serum log alkaline phosphatase (t = 6.7 in men; t = 7.2 in women) and serum protein (t = 5.3 in men; t = 4.4 in women) correlated positively with heart rate. CONCLUSION: At the population level, blood pressure, cigarette smoking, serum alkaline phosphatase and serum protein correlate independently, significantly and positively with heart rate, and age, height and serum phosphorus negatively.  (+info)

Resistance to remnant nephropathy in the Wistar-Furth rat. (8/1429)

The Wistar-Furth rat, an inbred strain resistant to actions of mineralocorticoids, was used to study the concept that mineralocorticoids contribute to progressive renal injury. It was postulated that if chronic nephropathy depends on aldosterone and if Wistar-Furth rats are resistant to aldosterone, remnant nephropathy would be attenuated in Wistar-Furth rats. Wistar-Furth rats and control Wistar rats were subjected to 5/6 nephrectomy or a sham procedure and then followed for 4 wk. Renal ablation resulted in hypertension at 4 wk in both strains (164+/-5 [Wistar-Furth] versus 184+/-7 [Wistar] mm Hg mean arterial pressure), with sham animals remaining normotensive (134+/-6 mm Hg). Renal damage in response to 5/6 nephrectomy was greatly decreased in Wistar-Furth rats compared with Wistar rats. Albuminuria was markedly less in Wistar-Furth rats (12.7+/-4.2 [Wistar-Furth] versus 97.4+/-22.6 [Wistar] mg/d per 100 g body wt, P<0.01). Glomerular damage, consisting of mesangial proliferation, mesangial lysis, and segmental necrosis, was observed in 42% of glomeruli from Wistar rats but in 0% of glomeruli from Wistar-Furth rats (P<0.01). To address the possibility that higher BP in partially nephrectomized Wistar rats mediated the greater renal damage, the study was repeated, with Wistar rats (not Wistar-Furth rats) being treated with a hydralazine-reserpine-hydrochlorothiazide regimen. Although this antihypertensive regimen equalized BP (conscious systolic) (144+/-8 mm Hg [Wistar] versus 157+/-7 mm Hg [Wistar-Furth] at 4 wk), albuminuria remained more than 10-fold greater in Wistar rats. In summary, renal damage upon 5/6 nephrectomy was markedly reduced in Wistar-Furth rats, a finding not attributable to reduced systemic BP. Since Wistar-Furth rats have been shown previously to be resistant to the actions of mineralocorticoids, the data from the present study support the hypothesis that aldosterone mediates, at least in part, the renal injury attendant to renal mass reduction.  (+info)

NIBP - Non-Invasive Blood Pressure. Looking for abbreviations of NIBP? It is Non-Invasive Blood Pressure. Non-Invasive Blood Pressure listed as NIBP
Did you ever wonder how your automatic blood pressure cuff actually works? No? Just me? Well…no surprise there.. When the machine inflates the cuff, its goal is to get it above the patients systolic blood pressure (table how it knows that for one second). It then uses this as its estimate for the next time it cycles. Incidentally, this is why the first pressure cycled on a new patient can be remarkably uncomfortable sometimes, or take a really long time.. While the cuff is cycling, a pressure sensor in the machine is looking for variance of the oscillations of the pressure in the cuff. When the cuff pressure exceeds the patients SBP there is no flow in the limb, and when the cuff pressure is below the patients DBP there is smooth flow in the limb, and the cuff pressure oscillations dont vary much. In between, there are variable amplitude micro-oscillations measurable in the cuff with each beat as some blood is squished through the artery.. ...
Continuous and noninvasive blood pressure (BP) measurement has been a topic of study for years, and many commercial devices have been available. The most commonly used technologies (applanation tonometry and vascular unloading method) have a shortcoming of complex mechanical structure. In this thesis, a new and systematic methodology of continuous and noninvasive BP measurement by pulse wave velocity (PWV) is established for people with healthy cardiovascular system. To avoid complex and high-cost sensor or control system, arterial pulse waves are acquired using the easy-to-use, low-cost and technically mature photoplethysmography (PPG) sensors. Critical parts of this study include modeling BP-PWV relationship, determining two PWVs related to systolic blood pressure (SBP) and diastolic blood pressure (DBP) respectively, and verifying the modeling methodology by practical BP measurement using PWV. The measurement results from a small population satisfy the accuracy criteria of the Association ...

Its best to make a salad dressing at home with healthy ingredients such as olive oil, vinegar, garlic, mustard, spices, and citrus juice. Therefore, its recommended that you manage your lifestyle habits to promote healthy blood pressure, especially since you cant control your race, age or family history. Eating what is a healthy blood pressure reading foods that are high in sodium (salt) can increase blood pressure. Secondary hypertension can occur suddenly and can result from the following illnesses: On any matter relating to your health high blood sugar after eating or well-being, please check with an appropriate what do you do when your blood sugar is high health professional.

A noninvasive blood pressure measuring system includes an inflatable cuff for encircling a portion of the human body. The cuff is inflated to a pressure sufficient to occlude arterial flow, and the pressure is then released by opening of a pressure relief valve for short periods of time to reduce the pressure until both the systolic and diastolic events have occurred. The incremental decrease in pressure with each opening of the pressure relief valve is controlled by monitoring the pressure before opening and after closing the pressure relief valve. The time duration of the next valve opening cycle is controlled as a function of the comparison of the two pressures so as to maintain an average incremental decrease in pressure. In addition to systolic and diastolic blood pressures, pulse rate is also determined by counting the number of pulses between the systolic and diastolic events and determining the time elapsed between the two events. After occurrence of the systolic event, the valve is opened
TY - JOUR. T1 - Near-continuous, noninvasive blood pressure monitoring in the out-of-hospital setting. AU - Thomas, Stephen H.. AU - Winsor, Greg. AU - Pang, Peter. AU - Wedel, Suzanne K.. AU - Parry, Blair. PY - 2005/1. Y1 - 2005/1. N2 - Objectives. This study was conducted to test out-of-hospital performance of a noninvasive radial artery tonometry device to assess blood pressure (BP), providing readings every 10-12 seconds. The primary objective was to determine the correlation between noninvasive BPs calculated with radial artery tonometry and standard oscillometric cuff methods. The secondary objective was to determine whether the difference observed between the two techniques was consistent over the range of BPs measured. Methods. This prospective trial enrolled adults transported by helicopter (n = 9 patients), fixed-wing airplane (n = 1), or ground vehicle (n = 10) of a single transport service. Patients had BP assessed simultaneously, by both standard automatic cuff and radial artery ...
A non-invasive blood pressure measurement device is used for determining blood pressure of an artery. The device comprises a housing unit, a base unit and a sensing unit. The base unit is pivotally connected to the housing unit and comprises electrical circuitry, a flexible ring, and a receptacle. The sensing unit comprises a pressure transducer for sensing pulses of the underlying artery, the transducer having a sensing surface, a flexible diaphragm having an active portion for transmitting blood pressure pulses of the underlying artery, interface means coupled between the sensing surface of the transducer and the flexible diaphragm for transmitting the blood pressure pulses within the underlying artery from the flexible diaphragm to the sensing surface of the transducer, a compressible ring, and connection means for detachably connecting the sensing unit to the receptacle of the base unit.

We present data based on two surveys four years apart (1987 and 1991) in Guildford and Carlisle. The sampling and methods used have been detailed elsewhere.6 15 16 Both surveys were carried out in the same sample of 10 primary schools in each town. The second survey included all children from the earlier survey still attending the schools together with similar numbers of children in the same classes. In both surveys measurements were made by a team of trained nurse observers, who visited schools in the two areas in sequence.. Blood pressure was measured after five minutes rest with the child seated and the arm supported at chest level. Three blood pressure measurements were made one minute apart on the right arm with the Dinamap 1846SX oscillometric blood pressure recorder (Critikon Inc, United States).17 All analyses were based on the means of the three readings. At 9-11 years all measurements were made with the adult size cuff (cuff bladder 22 cm × 12 cm); at 5-7 years all measurements were ...
The results point to the importance of getting multiple measures from different settings. Using just one reading as the basis for prescribing or adjusting blood pressure medication could endanger patients who suffer from "white coat" hypertension, the researchers say. They recommend using an average of at least six readings to get the best estimate of true blood pressure.. Home monitoring of blood pressure is becoming more popular. About 43 percent of people with high blood pressure use home monitors. Dr. Powers says the study results support recent calls for reimbursement of home blood pressure monitoring.. "I think patients should expect their doctors to make decisions based on home blood pressure [in addition to other measures]," he says. But, he adds, those who use a home blood pressure monitor should get it validated for accuracy at their doctors office.. Always talk with your health care provider to find out more information.. ...

I found this particularly useful because Ive lost a lot of weight over the past year and I suspected (correctly) that my blood-pressure medication was excessive for my current weight, and my blood pressure was actually lower than desirable. My doctor is a great guy (Dr. Shawn Foley at Philomath Family Medicine), and he more or less turned me loose to tune my medication so Im within his guidelines.. Another thing I found out was that I was a little intimidated by the process of having my blood pressure taken, and this tension made my blood pressure rise! So my medication had been tuned to deal with an anomalously high blood pressure. Taking reading a zillion times with this automated machine got me used to it, so now I ...

Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Oslers sign of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed. There is normal blood pressure when it is measured from within the artery. This condition however is associated with significant cardiovascular disease risk. Because the stiffened arterial walls of arteriosclerosis do not compress with pressure normally, the blood pressure reading is theoretically higher than the true intra-arterial measurement. To perform the test, one first inflates the blood pressure cuff above systolic pressure to obliterate the radial pulse. One then attempts to palpate the radial artery, a positive test is if it remains palpable as a firm "tube". It occurs frequently in the elderly irrespective of them being hypertensive, and has moderate to modest intraobserver and interobserver ...

Following the design of our pilot study, patients consenting to two sets of blood pressure readings will be randomly allocated using a random number table to either automated blood pressure measurement using a BpTRU device in an exam room (private area without any traffic or staff) with the door closed, or BpTRU in an open (non-private area) of the clinic with routine office traffic and noise levels. Patients randomized to the private area first will be subsequently tested in the non-private area and those randomized to the non-private area first will then be tested in the private area. A single portable BpTRU machine will be used for all recordings. A research assistant will be trained on the use of the equipment with at least five supervised training readings. The BpTRU device will be placed on the patients arm and readings will be recorded by the research assistant. The first reading will be done with the research assistant present to ensure proper placement and recording. The patient will ...

NIBP or Non-Invasive Blood Pressure Measurement devices are a method by which a cuff is placed around the limb to test the blood pressure levels of a patient. Non-Invasive Blood Pressure Methods include Ocsillometry, Auscultation, Doppler Ultrasound and Palpation. As the importance of NIBP measurement grows in the field of medical testing, so does the need for NIBP simulators. The function of an NIBP simulator is to reproduce the pressure profile of a patient while the blood pressure is being measured. This is accomplished by creating varying levels of pressure as opposed to the human blood pressure. It is important to find the ideal source to purchase medical devices such as NIBP and ECG simulators to be assured of quality and standard ...

Blood pressure refers to the force of blood against the artery walls, whereas a persons pulse indicates the number of times the heart beats per minute.. A resting heart rate is when a person is sitting, lying down, or not engaged in an activity.. An active heart rate is when a person is exercising or engaged in physical activity.. Everyone has a slightly different resting heart rate, but the average rate is between 60 and 100 beats per minute. A physically active person may have a heart rate as low as 40 beats per minute.. Similarly to blood pressure, a persons heart rate or pulse indicates how healthy the heart is.. ...

Clinical Question: Should a single elevated blood pressure reading in patients with hypertension cause concern?. Setting: Outpatient (primary care). Study Design: Cohort (retrospective). Synopsis: The authors of this study used an electronic medical record to identify a cohort of 5,825 patients with hypertension who were seen in 1993. They supplemented the electronic medical record with 1999 death registry data to determine whether a single elevated blood pressure reading was associated with adverse events. The outcomes of interest were acute myocardial infarction, stroke, ischemic heart disease, heart failure, kidney failure, or death from any cause. The research team identified a set of variables they thought might be associated with these outcomes and extracted them from the electronic medical record. From the pool of eligible patients, they randomly created two cohorts, one from which to derive prediction models and one for validating the models.. At the end of the five years of follow-up, 7 ...
Have a personal history of vascular disease, heart attack, or stroke. Symptoms include fatigue, heaviness, tiredness, and cramping in the leg muscles during walking or climbing activities. Other signs are leg pain that disturbs sleep, sores or wounds on the toes or feet, color changes in the skin of feet, a lower temperature in one leg as compared to the other, and poor nail growth and decreased hair growth on toes and legs.. If any of this applies to you, the first step is to ask your doctor about your risk for P.A.D. The provider will take a medical and family history, perform a physical exam, and conduct diagnostic tests. You may even be asked to have a simple noninvasive test called an ankle-brachial index (ABI). Painless and easy, the ABI compares the blood pressure readings in your ankles with the blood pressure readings in your arms.. If the blood flow in one of your limbs is completely or almost completely blocked, you may benefit from having a procedure or surgery in addition to ...

As Dr. Logan Silva pointed out, the common errors of a poorly fitting cuff, instrument miscalibration, and sloppy technique all contribute to imprecise blood pressure measurement. Unless we insist on high standards for blood pressure measurement, the reported value may not mean much (1). In addition, terminal digit preference (for example, the tendency to report manual readings with 0 or 5) and remeasurement of blood pressure when the initial value is high but never when it is normal are common biases. There is substantial room for improvement in our implementation of standards for blood pressure measurement ...

I came within an hour of having an emergency c/s at week 33 with my son. They even went as far to have the surgical resident (who would be assisting my regular OB) and the anesthesiologist speak with me. They were just waiting for my regular OB to get to the hospital and see me before they prepped me. When he did come in and see me, the first thing he did was take my BP. When he reached for the BP cuff, he said, "Is this the cuff theyre using to check your pressure with?" I said yes, then he went out and yelled up one side and down the other to the nursing staff about jeopardizing his patient and baby because they didnt use the large cuff. It made a huge difference! The readings went from [about] 180/104 to [about] 114/63. Surgery cancelled ...

www.today.com  Your blood pressure offers an important glimpse into your health, but you could get even more clues by making a small change when you get it checked. Ask to have your blood pressure taken in both arms, not just one. Its standard procedure in cardiologists offices, but not a usual practice in primary care. Healthy people can have slightly different numbers between arms, but a substantial difference in the readings could signal a blockage or an abnormality, said Dr. Sharonne Hayes, director of the Womens Heart Clinic at the Mayo Clinic in Rochester, Minnesota.

CHICAGO (AP) - Lowering blood pressure more than usually recommended not only helps prevent heart problems, it also cuts the risk of mental decline that often leads to Alzheimers disease, a major study finds. Its the first time a single step has been clearly shown to help prevent a dreaded condition that has had people trying crossword puzzles, diet supplements and a host of other things in hope of keeping their mind sharp. In the study, people treated to a top blood pressure reading of 120 instead of 140 were 19 percent less likely to develop mild cognitive impairment. They also had fewer signs of damage on brain scans, and there was a possible trend toward fewer cases of dementia.
Just 43% of adults with hypertension had their blood pressure under control, according to a report by the Centers for Disease Control.
A total of 412 hypertensive cases and 771 non-hypertensive controls from a Finnish 50-year-old cohort were included in this study.

But youre most likely to hear the term PHR for records that you keep on the Internet. Some provinces are working on tools that will let you enter and keep track of information like immunizations, medicines, test results, blood pressure readings, weight, and family health history. And your information will be protected so that only people with permission can see it.. The advantage of using a website provided by your health plan is that you can type in information. For example, you can type in results of blood pressure tests you do at home. And when you see your doctor for a checkup or for treatment, he or she can see those home test results with just a few taps on the keyboard.. Quick access to information like that can help your doctor give you the best care possible.. ...

An ambulatory blood pressure monitor is a small device that you wear throughout the day, usually for 24 or 48 hours. The device takes your blood pressure automatically while you do your normal daily activities.. The device periodically inflates and takes blood pressure measurements, which are recorded for later printout and analysis. The devices are usually loaned by a clinic, hospital, or pharmacy.. Your doctor might ask you to use one of these monitors after measuring your blood pressure in the doctors office, to make sure that you actually have high blood pressure. This is because your blood pressure can change during the day. And sometimes blood pressure is higher only because you are seeing a doctor. This is called white-coat hypertension. To diagnose high blood pressure, your doctor needs to know if your blood pressure stays high throughout the day. If you are required to use an ambulatory blood pressure monitor, keep in mind that it is important for a health professional to properly size ...

PMID: 16479762 Purpose: The aim of this study was to evaluate the effect of individually prescribed oral appliances for the treatment of obstructive sleep apnea syndrome (OSAS) on blood pressure, as well as factors influencing the efficacy. Materials and Methods: One hundred sixty-one patients (121 men and 40 women, mean age: 54.3 13.7 years) diagnosed with mild to moderate OSAS (mean apnea-hypopnea index: 17.9 14.1) were studied before and after insertion of a mandibular advancement device, with a mean interval of 60 days. Systolic, diastolic, and mean blood pressure was taken using an automatic blood pressure monitor (132.0 16.1 mmHg, 82.1 10.6 mmHg, 107.1 12.9 mmHg, respectively, at baseline). Results: The patients were subdivided into 3 groups: responder, partial responder, and nonresponder, according to the difference of mean arterial pressure fall after the treatment. The systolic, diastolic, and mean blood pressure decreased significantly (P < .001) (127.5 15.0 mmHg, 79.2 10.0 mmHg, 103.4 ...
The aim of present study was to evaluate relationships between degree of portal hypertension, severity of the disease, and bleeding status in patients with liver cirrhosis. Patients and methods. All study patients with liver cirrhosis underwent hepatic venous pressure gradient measurements, endoscopy, clinical and biochemical evaluation. Liver function was evaluated according to Child-Turcotte-Pugh (Childs) scoring system. Patients with decompensated cirrhosis (presence of severe ascites, acute variceal bleeding occurring within 14 days, hepatorenal syndrome, cardiopulmonary disorders, transaminase levels >10 times higher the upper normal limit), active alcohol intake, use of antiviral therapy and/or beta-blockers were excluded from the study. Results. One hundred twenty-eight patients with liver cirrhosis (male/female, 67/61; mean age, 53.8±12.7 years) were included into the study. Etiology of cirrhosis was viral hepatitis, alcoholic liver disease, cryptogenic and miscellaneous reasons in 57, 49,
