Accurate arm circumference (AC) measurement is required for accurate blood pressure (BP) readings. Standards stipulate measuring arm circumference at the midpoint between the acromion process (AP) and the olecranon process. However, which part of the AP to use is not stipulated. Furthermore, BP is measured sitting but arm circumference is measured standing. We sought to understand how landmarking during AC measurement and body position affect cuff size selection. Two variations in measurement procedure were studied. First, AC was measured at the top of the acromion (TOA) and compared to the spine of the acromion (SOA). Second, standing versus seated measurements using each landmark were compared. AC was measured to the nearest 0.1 cm at the mid-point of the upper arm by two independent observers, blinded from each other\'s measurements. In 51 participants, the mean (±SD) mid-AC measurement using the anchoring landmarks TOA and SOA in the standing position were 32.4 cm (±6.18) and 32.1 cm (±6.07), respectively (mean difference of 0.3 cm). In the seated position, mean arm circumference was 32.2 (±6.10) using TOA and 31.1 (±6.03) using SOA (mean difference 1.1 cm). Kappa agreement for cuff selection in the standing position between TOA and SOA was 0.94 (p < 0.001). The landmark on the acromion process can change the cuff selection in a small percentage of cases. The overall impact of this landmark selection is small. However, standardizing landmark selection and body position for AC measurement could further reduce variability in cuff size selection during BP measurement and validation studies.

Intra-arterial blood pressure (IABP) measurement, although considered the gold standard in critically ill children, is associated with certain risks and lacks widespread availability. This study was conducted to determine the differences and agreements between oscillometric non-invasive blood pressure (NIBP) and invasive IABP measurements in children. Inclusion criteria consisted of children (from 1 month to 18 years) admitted to the pediatric intensive care unit (PICU) of a teaching hospital who required arterial catheter insertion for blood pressure (BP) monitoring. The comparison between IABP and NIBP was studied using paired t -test, Bland-Altman analysis, and Pearson\'s correlation coefficient. In total, 4,447 pairs of simultaneously recorded hourly NIBP and IABP measurements were collected from 65 children. Mean differences between IABP and NIBP were -3.6 ± 12.85, -4.7 ± 9.3, and -3.12 ± 9.30 mm Hg for systolic, diastolic, and mean arterial BP, respectively ( p  < 0.001), with wide limits of agreement. NIBP significantly overestimated BP ( p  < 0.001) in all three BP states (hypotensive, normotensive, and hypertensive), except systolic blood pressure (SBP) during hypertension where IABP was significantly higher. The difference in SBP was most pronounced during hypotension. The difference in SBP was significant in children <10 years ( p  < 0.001), with the maximum difference being in infants. It was insignificant in adolescents ( p  = 0.28) and underweight children ( p  = 0.55). NIBP recorded significantly higher BP in all states of BP except SBP in the hypertensive state. SBP measured by NIBP tended to be the most reliable in adolescents and underweight children. NIBP was the most unreliable in infants, obese children, and during hypotension.

The latest guidelines for the management of arterial hypertension, the silent killer, were published in summer 2023. They particularly emphasize again the quality of blood pressure measurement which ideally should always be automated using oscillometric device and an arm cuff already in the consulting room. They remind you how to manage the blood pressure of a patient whose hypertension has been confirmed, to stimulate drug compliance and to avoid therapeutic inertia. A holistic view of the patient with all his or her risk factors is always required. The general practitioner is the key player in the diagnosis, treatment and monitoring of the hypertensive patient whose therapeutic education has been as complete as possible with practice of self-measurement of blood pressure at home if possible. The goal is to normalize blood pressure within the first three months of treatment initiation and to reduce as much as possible the cardiovascular risk of the treated patient in the frame of preventive medicine.
Les dernières directives de prise en charge de l’hypertension artérielle, le tueur silencieux, ont été publiées à l’été 2023. Elles insistent particulièrement, à nouveau, sur la qualité de la mesure de la pression artérielle qui, idéalement, doit être automatisée toujours à l’aide d’un brassard et ce, déjà au cabinet de consultation. Elles rappellent comment gérer la pression artérielle d’un patient dont l’hypertension a bien été confirmée, comment stimuler l’adhérence au traitement et éviter l’inertie thérapeutique. Une vue globale du patient avec tous ses facteurs de risque est toujours de rigueur. Le médecin généraliste est l’acteur-clé du diagnostic, du traitement et du suivi du patient hypertendu dont l’éducation thérapeutique a été la plus complète possible avec pratique de l’automesure tensionnelle à domicile si possible. Le but est de normaliser la pression artérielle dans les trois premiers mois de la prise en charge et de réduire le plus possible le risque cardiovasculaire et rénal du patient traité dans le cadre d’une médecine préventive.

BACKGROUND: International standards used for device validation protocols require that the reference cuff conform to a width and length that is 37 to 50% and 75 to 100% of the arm circumference, respectively. However, there is no published chart of appropriate width and length dimensions across the range of arm circumferences. Our objective was to create a chart that could be used to guide reference cuff selection and compare recommended dimensions with two common cuff systems.
METHODS: Arm circumferences, ranging from 22 to 52 cm were used to create a reference table for width and length requirements. Arm circumferences were grouped following the American Heart Association recommendation for cuff sizes. Cuff dimension data was extracted from the website of a cuff system commonly used for validations (the Baum Corporation) and compared both the American Heart Association recommendations and Baum sizes with the recommended reference dimensions.
RESULTS: There were discrepancies in size naming conventions between the Baum Corporation and the American Heart Association cuff systems. Moreover, there were gaps in both systems where the cuff would not be recommended for validation (31-32 cm for Baum and 30-31 cm for the American Heart Association). Neither system had cuffs that could be used for the largest arm circumferences.
CONCLUSIONS: Our chart highlights the need for more than one cuff system in validation studies and the critical need for cuffs that could be used for validation among larger arm circumferences.

Background: Musculoskeletal disorders (MSDs) occur as a result of long-term exposure to inappropriate working postures and repetitive use of body postures, leading to harmful consequences for patients, employees, and employers. Evaluating distinct working postures can contribute to effective interventions. Purpose: The aim of this study was to determine ergonomic risks of MSDs during repeated blood pressure measurement processes and to evaluate the effectiveness of a training on this topic. Methods: A pretest/posttest quasi-experimental design studied 64 nurses in a training and research hospital in Turkey. Participants were evaluated for the prevalence and risk of MSDs using the Nordic Musculoskeletal Questionnaire Extended Version and the Rapid Entire Body Assessment (REBA) Checklist, and by photographing them performing the procedure. Nurses with high risk for MSDs received an ergonomics training program and were followed up twice in 3 months. Results: Reduction in prevalence of MSDs in neck, shoulder, and hip/thigh areas, and in mean REBA scores after the training were statistically significant. Conclusion: Nurses should be trained about correct posture for specific high-risk activities that may cause MSDs, and offered exercise programs that support the musculoskeletal system.

BACKGROUND: The effect of clothing on the recording of blood pressure in a normotensive and hypertensive population remains essential to diagnosing and managing.
METHODS: This is a cross-sectional study to measure blood pressure using a validated oscillometric sphygmomanometer in two populations. The records were made over the thicker sleeve arm and non-sleeved arm (either on bare arm or indicating the removal of the outermost garment). Clothing was categorized according to how patients attended the outpatient clinic based on the real world.
RESULTS: A total of 75 patients were included with a diagnosis of hypertension whose mean age was 67.1 years (SD ± 16.3). The group of normotension included 63 patients whose mean age was 21.1 years (SD ± 2.2). There was not variability related to technique or inherent to the condition of the subject on the first and second measurements of blood pressure. In the comparative analysis, the group with normotension did not report a significant difference in systolic or diastolic blood pressure due to the effect of clothing during the first or second measurement (p > 0.05). In the group with hypertension, a significant difference was observed in the first measurement, between the group over-the-sleeve and non-sleeved arm (systolic blood pressure, p: 0.021 and diastolic, p: 0.001). However, when the variable order of measurement was analyzed by randomizing the initial registry with or without clothing was not found a statistical difference.
CONCLUSIONS: Clothing does not a significant difference in the measure of blood pressure in a normotensive or hypertensive population.

UNASSIGNED: Some brachial cuffs for oscillometric blood pressure (BP) measurement are claimed to cover a wide range of upper-arm circumferences; however, their validation is rarely conducted. Our aim was to compare oscillometric BP measurements obtained with a universal cuff with those obtained with an appropriately sized cuff.
UNASSIGNED: We utilised the Microlife B6 Connect monitor, conducting oscillometric BP measurements in a random sequence with both a universal cuff (recommended for arm circumferences from 22 to 42 cm) and an appropriately sized cuff (medium for circumference 22-32 cm and large for 32-42 cm). We included 91 individuals with an arm circumference of 22-32 cm and 64 individuals with an arm circumference of 32-42 cm.
UNASSIGNED: For arm circumferences > 32 cm, systolic and diastolic BP measured with the universal cuff was higher than that measured with the large cuff (systolic 6.4 mmHg, 95% confidence interval [CI]). 3.9-8.8, diastolic 2.4 mmHg, 95%CI, 1.2-3.7, p < 0.001 for both). Overestimation of BP with the universal cuff was statistically significant after correcting for the sequence of measurements. No statistical difference was found between the universal cuff and medium cuff for circumferences in the 22-32 cm range. The bladder size in the universal cuff matched the dimensions of the medium-sized cuff; however, the cuff was larger.
UNASSIGNED: Overestimation of BP measured with a universal cuff in persons with large arm circumferences is clinically important. It poses the risk of unnecessary initiation or intensification of antihypertensive medication in persons using the universal cuff.
What is the context?Clinical guidelines recommend individualisation of the size of the cuff used for blood pressure measurement according to the circumference of the upper arm.Many blood pressure monitors are sold with a single “universal” cuff claimed to cover a wide range of upper arm sizes.We compared blood pressure obtained with the Microlife B6 Connect monitor and a “universal” cuff with the results obtained with individual sized cuffs (medium size for arm circumference between 22 and 32 cm and large size for arm circumference between 32 and 42 cm).What is new?In persons with large upper arm circumference is the systolic blood pressure 6.4 mmHg higher and the diastolic blood pressure 2.4 mmHg higher with the universal cuff than with the individual-sized large cuff.What is the impact?The universal cuff overestimates blood pressure in persons with large arm circumference.

Serial blood pressure and heart rate measurements, particularly obtained by the patients at home, are currently recommended for the management of patients.
Home blood pressure and heart rate measurements were obtained by an 81-year old husband and his 74-year old wife in the morning and evening, over the course of an entire month.
Morning and evening systolic blood pressure (129.9 ± 5.5, 125.9 ± 10.2, respectively), and diastolic blood pressure (69.2 ± 4.0, 70.1 ± 5.3) were not different (P > .05), heart rate (61.2 ± 2.9, 69.0 ± 5.5) was higher in the evening (P = .00001) in the husband, while systolic blood pressure (134.7 ± 9.6, 119.0 ± 12.0) and diastolic blood pressure (78.6 ± 5.6, 72.1 ± 7.3) were higher in the morning (P = .00001, P = .00031), and heart rate (62.7 ± 4.7, 68.2 ± 4.6) was higher in the evening (P = .00017) in the wife.
Patient-generated serial home blood pressure and heart rate logs provide essential data for the patients\' management and could potentially be useful in research; circadian variation of blood pressure and heart rate calls for implementation of chronotherapeutic principles for the time of drug administration.

UNASSIGNED: Hypertension is a major public health problem, thus, its timely and appropriate diagnosis and management are crucial for reducing cardiovascular morbidity and mortality. The aim of the new Hungarian Hypertension Registry is to evaluate the blood pressure measurement practices of general practitioners (GPs), internists and cardiologists in outpatient clinics, as well as to assess the seasonal variability of blood pressure.
UNASSIGNED: Omron M3 IT devices were used during four-month periods between October 2018 and April 2023 in GP practices and in hypertension clinics. The blood pressure data were then transmitted online from the monitors\' cuffs to a central database using the Medistance system of Omron.
UNASSIGNED: Family physicians (n = 2491), and internists/cardiologists (n = 477) participated in the study. A total of 4804 821 blood pressure measurements were taken during 10 four-month evaluation periods. In the ten periods, the daily average number of measurements was between 3.0 and 5.6. Following ESH diagnostic criteria, the proportion of subjects in optimal, normal and high-normal blood pressure categories were 14, 13.4 and 16.7%, respectively. Altogether 56% of the measurements belonged to stage 1, stage 2 or stage 3 hypertension categories (31.6, 17.1 and 7.4%, respectively). On average, a difference of 5/2 mmHg was observed between winter and summer data in systolic and diastolic blood pressures, respectively. The average systolic blood pressure values were higher in GP practices with more than 2000 patients than in the ones with less than 1500 patients (141.86 mmHg versus 140.02 mmHg, p < 0.05).
UNASSIGNED: In conclusion, the low daily average number of blood pressure measurements indicates a limited blood pressure screening awareness/capacity in the case of Hungarian family physicians. In GP practices with more patients, blood pressure is usually less well-controlled. These results suggest that the further promotion of home blood pressure monitoring is necessary.
What is the background?The standard method for the diagnosis of hypertension and for the control of treatment efficacy in hypertensive patients is office blood pressure measurement.Until now we had no real-life data on the blood pressure measurement practices of general practitioners (GPs), internists and cardiologists.Although seasonal differences in blood pressure values are well known, we had no data on the extent of these changes.What is new?In this real-world, nationwide observational study we were able to measure the frequency of blood pressure measurements in the daily practice of GPs, internists and cardiologists in Hungary, which was found to be very low compared to the number of patients they treat. In practices with more patients, blood pressure is generally less well-controlled.We could also detect a significant seasonal variation in systolic and diastolic blood pressure values over the observed time periods.What is the impact?The low daily average number of blood pressure measurements indicates a limited blood pressure screening awareness/capacity in the case of Hungarian family physicians, supporting the further promotion of home blood pressure measurement.The marked seasonal blood pressure changes demonstrated by our study require attention and the individual adjustment of treatment in different seasons.
