Abstract:

<p><strong>Objective</strong>: This study evaluated the agreement of blood pressure measurements obtained through different auscultatory and oscillometric automated/semi-automated monitors. <strong>Material</strong> <strong>and</strong> <strong>Methods</strong>: The blood pressure of 30 participants was evaluated by a single calibrated examiner. The measurements were carried out through either auscultatory monitor (mercury column or aneroid) or automated/semiautomated oscillometric pulse monitors. For each participant, 5 min rest was established by sitting on dental chair and the measurements were always carried out on the left arm, at the heart level. Three consecutive measurements were performed with the four monitors in each participant with a minimum time interval of five minutes between each measurement. All monitors were properly calibrated and certified by INMETRO. The results were submitted to intraclass correlation coefficient and Friedman’s analysis of variance. <strong>Results</strong>: The measurements of systolic blood pressure for both auscultatory and oscillometric methods were similar. The measurements of diastolic blood pressure for auscultatory monitors were similar (p > 0.05); as well as for oscillometric monitors (p > 0.05). However, when auscultatory and oscillometric monitors were compared, there were statistically significant differences in diastolic blood pressure (p < 0.05). <strong>Conclusion</strong>: It was verified a difference in the results between the auscultatory and oscillometric blood pressure monitors. The systolic blood pressure measurements exhibited similar correlations, while<br />diastolic blood pressure measurements showed different correlations. </p>

Abstract:

Aim: We analyzed to what extent measurement protocol influenced individual blood pressure (BP) and achievement of treatment target in patients with coronary heart disease. Methods: In a subsample of Czech EUROASPIRE III–V survey participants (n = 913), we compared the per-protocol BP measurement (by automated oscillometric device OMRON at the beginning of survey procedure) with control auscultatory measurement (by physician during interview). Results: Per-protocol approach produced significantly (p < 0.0001) higher BP values (by 9/6 mmHg in median) than auscultatory measurements and led to markedly higher proportion of patients over target BP (less than 140/90 mmHg; 59.3 vs 34.9% [p < 0.0001], per-protocol vs auscultatory technique, respectively). Conclusion: Per-protocol oscillometric technique was not equivalent to conventional auscultatory measurement and seriously over-rated the real nonachievement of BP target in observational surveys.

Abstract:

Mean brachial artery pressures determined by five different non-invasive automatic oscillometric and one auscultatory preferred (oscillometric back-up) blood pressure (BP) monitors were compared with mean arterial pressures (MAP) obtained by cannulation of the radial artery of the same arm. The devices tested all performed similarly, showing a wide range of variation (+40% to −29%) compared with the directly measured MAP, and all tended to over-read at low values and under-read at high values. Trend information was generally acceptable, but occasionally was misleading. In addition, using one of the devices, systolic and diastolic blood pressure measurements were compared with those obtained by auscultation. This gives a range of differences from +22 to −25 mmHg for systolic and +20 to −12 mmHg for diastolic BP measurements. (The average fell within 1.0 mmHg of the auscultatory measurement, with a standard deviation of 10 mmHg.) Thus, the automatic oscillometric BP monitors tested were comparable in accuracy to auscultatory BP measurement, and are satisfactory for routine use in the appropriate clinical context. However, in settings where significance is to be attached to individual BP readings rather than to trends, or where a high degree of accuracy is required, automatic oscillometric machines cannot be regarded as satisfactory alternatives to arterial cannulation.

Abstract:

ABSTRACT Objective: to compare blood pressure values obtained by auscultatory and oscillometric methods in different gestational periods, considering cuff width. Method: it is a cross-sectional and quasi-experimental study approved by the Research Ethics Committee. The sample consisted of 108 low-risk pregnant women. Blood pressure measurements were performed in gestational periods of 10-14, 19-22 and 27-30 weeks. Results: The oscillometric device presented values similar to the auscultatory method in systolic blood pressure, but overestimated diastolic blood pressure. Underestimation of blood pressure occurred when using the standard width cuff rather than the correct width cuff in both measuring methods. Conclusion: Verification of brachial circumference and use of adequate cuffs in both methods are indispensable to obtain reliable blood pressure values in pregnant women. We recommend performance of additional studies to evaluate diastolic blood pressure overestimation by the Microlife 3BTO-A.

Abstract:

Beat-to-beat variability of blood pressure (BP) hampers its exact measurements in patients with arrhythmias, which can give rise to diagnostic inaccuracies and accordingly wrong treatment. Aim: to assess whether BP measurement might be exact in patients with permanent atrial fibrillation when using the latest generation of high-accuracy oscillometric devices. Subjects and methods. The developed design was used to examine 15 patients and to make 44 comparisons of BP measurements. The inclusion criteria were permanent atrial fibrillation and evidence for hypertension. Results. BP levels measured by an objective auscultatory method (OAM), a traditional auscultatory method (TAM), and OMRON M6 device were compared. Considerable (more than 10 mm Hg) differences were found in the recordings taken by OAM and OMRON M6 during 6 (14%) systolic BP (SBP) and 4 (9%) diastolic BP (DBP) measurements. However, substantial differences were concurrently revealed in those obtained by the two auscultatory methods TAM and OAM in 3 (7%) and 4 (9%) measurements of SBP and DPB, respectively; which appears to be related to the general problems of BP measurements in arrhythmias. Conclusion. The conducted pilot study has generally confirmed that the up-to-date high-grade oscillometric tonometers (such as an OMRON 6) may be used to measure SBP and DBP levels in the presence of atrial fibrillation.

Abstract:

This study aimed to quantify blood pressure (BP) measurement accuracy and variability with different techniques. Thirty video clips of BP recordings from the BHS training database were converted to Korotkoff sound waveforms. Ten observers without receiving medical training were asked to determine BPs using (a) traditional manual auscultatory method and (b) visual auscultation method by visualizing the Korotkoff sound waveform, which was repeated three times on different days. The measurement error was calculated against the reference answers, and the measurement variability was calculated from the SD of the three repeats. Statistical analysis showed that, in comparison with the auscultatory method, visual method significantly reduced overall variability from 2.2 to 1.1 mmHg for SBP and from 1.9 to 0.9 mmHg for DBP (both p<0.001). It also showed that BP measurement errors were significant for both techniques (all p<0.01, except DBP from the traditional method). Although significant, the overall mean errors were small (−1.5 and −1.2 mmHg for SBP and −0.7 and 2.6 mmHg for DBP, resp., from the traditional auscultatory and visual auscultation methods). In conclusion, the visual auscultation method had the ability to achieve an acceptable degree of BP measurement accuracy, with smaller variability in comparison with the traditional auscultatory method.

Abstract:

ABSTRACT Objective: To adapt a pre-existing educational game, making it specific to the teaching of blood pressure auscultatory measurement, and to apply this game in a pilot study. Method: The original game cards were altered by the authors and submitted to content validation by six experts in the field. After redesigns, the game was applied to 30 subjects, who answered a questionnaire (pre-test and post-test) on auscultatory measurement. Data were analyzed descriptively and by the paired Student's t-test and paired Wilcoxon test. Results: Throughout the content validation process, 17 of the 28 original cards were modified. Of these 17 cards, 13 obtained 80% agreement, and the rest were modified according to the judges' suggestions. The obtained grades significantly increased between pre- and the post-test. Conclusion: It was concluded that the reformulated game presented satisfactory evidence of content validity. Its use as a teaching-learning method was effective for this sample.

Abstract:

Purpose. To evaluate the accuracy of measuring blood pressure (BP) by the ECG and Medicom-Combi daily blood pressure monitoring system, designed to monitor blood pressure with oscillometric and auscultatory methods, among adults in accordance with the European Hypertension Society’s International Protocol for validation of adult blood pressure measuring instruments (ESH‑2001). Materials and methods. Patients were recruited based on criteria recommended by the ESH‑2001 protocol. A total of 99 pairs of test and control measurements of blood pressure were obtained (three pairs of measurements for each of 33 subjects). The measurements were carried out sequentially on the same arm. For the arm circumference of 24–32 cm and 32–42 cm, two cuffs of the test complex were used (adult small and adult large, respectively). Results. When testing the complex, 66, 93, and 99 measurements were obtained within 5, 10, and 15 mmHg for systolic blood pressure (SBP) and 66, 89 and 95 measurements for diastolic blood pressure (DBP), respectively, using the oscillometric method, as well as 71, 93 and 97 measurements for SBP and 71, 84 and 93 measurements for DBP, respectively, when using the auscultatory method. The mean ± SD of the differences between the test and control measurements were 1.8 ± 5.4 / 1.6 ± 6.9 mmHg for SBP / DBP using the oscillometric method and 0.8 ± 5.9 / –1.2 ± 7.9 mmHg for SBP / DBP using the auscultatory method. Conclusion. The complex of daily monitoring of ECG and blood pressure Medicom-Combi, designed for daily monitoring of blood pressure, meets the requirements stated in the international protocol ESH‑2001 (class ‘Passed’) for adults and is recommended for use in clinical practice.

Abstract:

This study compared blood pressure and heart rate measurements provided by the Quinton 410 automated exercise monitor with simultaneous auscultatory and electrocardiograph readings during rest, postural change, immediately after each treadmill exercise workload, and during active recovery in a sample of young children (mean age 7.9 yrs). The Quinton 410 provided highly accurate heart rates under all conditions (average mean difference <1.0 bpm). The Quinton systolic readings correlated well with and were similar to auscultation across conditions except for the initial treadmill workload. Slightly weaker relationships were observed between the Quinton and K4 diastolic comparisons. Compared with K4 auscultatory readings, the Quinton 410 provided slightly lower diastolic pressures across conditions (average mean difference = 3.1 mmHg). These findings provide preliminary evidence that for group comparisons with children, the Quinton 410 provides acceptable blood pressure estimates resulting from a variety of events, including exercise.

Abstract:

: Hypertension is a potent risk factor for cardiovascular morbidity and mortality. High blood pressure (BP) correlates closely with all-cause and cardiovascular mortality. Although the gold standard remains office BP (auscultatory or automated), other methods (central or out-of-office) are gaining popularity as better predictors of CV events. In this review, we investigated the prognostic value of each method of BP measurement and explored their advantages and pitfalls. Unattended automated office BP is a novel technique of BP measurement with promising data. Ambulatory BP monitoring, and to a lesser extent, home BP measurements, seem to predict cardiovascular events and mortality outcomes better, while at the same time, they can help distinguish hypertensive phenotypes. Data on the association of central BP levels with cardiovascular and mortality outcomes, are conflicting. Future extensive cross-sectional and longitudinal studies are needed to evaluate head-to-head the corresponding levels and results of each method of BP measurement, as well as to highlight disparities in their prognostic utility.

Abstract:

Blood pressure is a vital parameter. Stephen Hales first measured BP and Scipione Riva-Rocci developed the prototype of the present day sphygmomanometer. Both directly and indirectly BP can be measured. The indirect method Includes sphygmomanometric method, ultrasound doppler method, oscillometric method, self measurement and ambulatory BP monitoring. For proper measurement of BP by auscultatory method, one should have adequate knowledge of equipment and cuff size, proper technique and Korotkoff sounds. In different situations like arrhythmias, shock, hyperkinetic circulatory states and aortic regurgitation, BP should be measured carefully. In recent years home BP monitoring and ambulatory BP monitoring are becoming popular. Care must be taken to avoid both underestimation and overestimation of BP recording. doi: 10.3329/uhj.v5i1.3438 University Heart Journal Vol. 5, No. 1, January 2009 28-31

Abstract:

Objective. To assess the clinical signifcance of auscultatory gap (AG) found by the 24-hour ambulatory blood pressure monitoring (ABPM) using the Korotkoff’s sounds (KS) and its potential causes.Design and methods. 24-hour ABPM was performed in 60 patients (mean age 51,3 years, range 22–85 years), including 24 women and 36 men. In 24 patients, hypertension was diagnosed. In total, 2333 blood pressure (BP) measurements without “noise contamination” were selected for subsequent analysis (38,9 measurements per patient; from 28 to 73 measurements). The simultaneous recording of electrocardiogram (ECG), brachial cuff pressure, and KS phonograms on the right hand, as well as continuous recording of non-invasive BP curve in the left fnger using the volume clamp technique were performed in 10 patients with AG.Results. Based on the 24-hour ABPM, AG was shown in 43 of 60 subjects (71,7%). The AG was found to be associated with a decreased amplitude of ﬂuctuations of the cuff pressure; upon its termination, the amplitude recovered. The above synchrony of changes in KS and amplitude of pressure ﬂuctuations was found in all 124 cases which demonstrated AG during BP measurement. We assume that AG is a true variation of BP rather than a feature of KS, as the ﬂuctuation amplitude depends on the ratio of BP and cuff pressure but does not depend on the KS phase. To test the hypothesis, the cuff pressure and KS were compared to the continuously monitored arterial pressure. When the systolic arterial pressure exceeded the cuff pressure, the KS appeared. Later on, the BP ﬂuctuations led to a decrease in systolic BP; the arterial pressure did not reach the cuff pressure and, therefore, KS were not recorded. Subsequent decrease in the cuff pressure led to re-appearance of KS.Conclusions. The auscultative gap phenomenon is associated with true (mostly respiratory) variations of systolic BP rather than with features of KS in individual patients. The initial and repetitive KS occur at certain systolic BP levels depensing on the BP respiratory ﬂuctuations and may indirectly indicate the amplitude of ﬂuctuations.

Abstract:

Background: Hypertension screening programs have been effective in raising awareness and identifying people who are otherwise unfamiliar with their disease. We aimed to develop a resource-minimal, evidence-based protocol for a novel medical student-organized hypertension-screening program capable of community implementation. Methods: Eighty-one medical students had their blood pressure measured once using an automated machine and once using the manual auscultatory method. Bland-Altman plots compared agreement between measurement techniques. Results: No significant difference between manual and automated techniques was noted in the measurement of systolic blood pressure, but was noted for diastolic blood pressure. Conclusions: In the context of a community-based screening program, automated and manual measurements may be used interchangeably to obtain an accurate measure of systolic blood pressure. A medical student-organized community-screening program is an effective way to screen large numbers of people in a short amount of time.

Abstract:

The blood pressure patterns obtained from a linearly or stepwise deflating cuff exhibit personalized traits, such as fairly uniform peak patterns and regular beat geometry; it can support the diagnosis and monitoring of hypertensive patients with reduced sensitivity to fluctuations in Blood Pressure (BP) over time. Monitoring of personalized trait in Oscillometric Arterial Blood Pressure Measurements (OABPM) uses the Linear Discriminant Analysis (LDA) algorithm. The representation of personalized traits with features from the oscillometric waveforms using LDA algorithm includes four phases. Data collection consists of blood pressure data using auscultatory measurements and pressure oscillations data obtained from the oscillometric method. Preprocessing involves the normalization of various sized oscillometric waveforms to a uniform size. Feature extraction involves the use of features from oscillometric amplitudes, and trait identification involves the use of the LDA algorithm. In this paper, it presents a novel OABPM-based blood pressure monitoring system that can monitor personalized blood pressure pattern. Our approach can reduce sensitivity to fluctuations in blood pressure with the features extracted from the whole area in oscillometric arterial blood pressure measurement. Therefore this technique offers reliable blood pressure patterns. This study provides a cornerstone for the diagnosis and management of hypertension in the foreseeable future.

Abstract:

Despite frequent reporting of blood pressure (BP) during profound passive heat stress, both with and without a hypotensive challenge, the method by which BP is measured often varies between laboratories. It is unknown whether auscultatory and finger BP measures accurately reflect intra-arterial BP during dynamic changes in cardiac output and peripheral resistance associated with the aforementioned conditions. The purpose of this investigation was to test the hypothesis that auscultatory BP measured at the brachial artery, and finger BP measured by the Penaz method, are valid measures of intra-arterial BP during a passive heat stress and a heat-stressed orthostatic challenge, via lower body negative pressure (LBNP). Absolute (specific aim 1) and the change in (specific aim 2) systolic (SBP), diastolic (DBP), and mean BPs (MBP) were compared at normothermia, after a core temperature increase of 1.47 ± 0.09°C, and during subsequent LBNP. Heat stress did not change auscultatory SBP (6 ± 11 mmHg; P = 0.16), but Penaz SBP (−22 ± 16 mmHg; P < 0.001) and intra-arterial SBP (−11 ± 13 mmHg P = 0.017) decreased. In contrast, DBP and MBP did not differ between methods throughout heat stress. Compared with BP before LBNP, the magnitude of the reduction in BP with all three methods was similar throughout LBNP ( P > 0.05). In conclusion, auscultatory SBP and Penaz SBP failed to track the decrease in intra-arterial SBP that occurred during the profound heat stress, while decreases in arterial BP during an orthostatic challenge are comparable between methodologies.

Abstract:

Due to continuous debate of incompatible results of blood pressure by the two devices such as the automated oscillometer and the traditional mercury sphygmomanometer, a study was carried out to compare the accuracy of the two devices as well as the best position to measure blood pressure. A comparative study regarding the difference in values of BP (mmHg) between traditional auscultatory method and automated oscillometric readings in supine and sitting positions was conducted among medical students. Oscillometer produced high readings than the readings of sphygmomanometer. Besides, the blood pressure readings for systolic and diastolic are higher while sitting when compared to supine position as the blood is unevenly distributed to all part of the body in sitting position. This will lead to the increase in ionotropic effect of the heart to pump blood towards the upper part of the body. The differences between two methods showed there have a major problem or error in measuring blood pressure. It is therefore necessary to improve the method and ways to check the health especially in this area where slight differences may contribute to large errors.
