“…SBP showed a mean difference of 15.32±1. 25 [18]. The results were in concordance with ours, as it showed high values of SBP recorded by automated instrument [19].…”

“…Automated device is used for BP estimation in day-to-day clinical practice in multiple settings such as outpatient, critical care, and continuous BP monitoring. Critical decision and pharmacological interventions are done based on this parameter [25,26]. We observed from our results that there is a higher value of recorded BP with automated device, especially in hypertensives.…”

Objectives: Automatic devices based on oscillometric principle are widely used for the estimation of blood pressure (BP). Mercury sphygmomanometer mean systolic BP (MSBP) and its derived cuff pressure are the traditional mode of estimation which is a validated and authenticated procedure. Automated machines using oscillometric method are slowly replacing the conventional technique. This study was done to compare the BP recorded by the mercury sphygmomanometer MSBP and the automated technique using oscillometric method automated office BP (AOBP). Methods:Two hundred subjects aged 40-65 years with mid-arm circumference 27-34 cm were recruited. MSBP and AOBP were recorded adhering to guidelines given by the American Heart Association Joint National Committee. The subjects were divided into two groups as normotensive (Group 1) and hypertensive (Group 2), and statistical analysis was performed. Results:The mean systolic and diastolic pressures estimated by oscillometric method and sphygmomanometer were calculated and compared with each other by paired t-test separately for Groups 1 and 2. In mormotensives (Group 1), the mean systolic pressure MSBP was 114.21±7.5 mmHg and AOBP was 118.24±11.0 mmHg. The mean diastolic MSBP was 72.1±3.5 mmHg and AOBP was 76.4±1.2 mmHg. Subjects of Group 2 (hypertensive) showed mean systolic pressure MSBP of 144.42±18.5 mm Hg and AOBP of 159.74±22 mmHg. The mean diastolic MSBP was 87.2±9.5 mmHg and AOBP was 96.9±9.2 mmHg. In Group 1, the difference was statistically not significant, while in Group 2, comparison by paired t-test showed a mean difference of systolic pressure by 15.32±1.25 (p<0.005), and mean difference of diastolic pressure by 8.9±5.8 (p<0.005). Conclusion:Hence, we conclude that oscillometric pressure recordings by the automated device are closer to manual measurements in normotensives but showed a significant high value in hypertensives. We suggest caution in treating hypertensives with values derived from automated machines only.

“…For blood pressure, we focused on results for SBP since it is a better predictor of long term outcomes (20) and is more accurately measured than DBP (21). Biomarkers that were not normally distributed (triglycerides, HOMA-IR, CRP, and IL-6) were natural log-(ln)-transformed prior to use in the regression models.…”

Purpose To investigate whether preterm birth (PTB) is associated with greater cardiovascular disease (CVD) risk in a longitudinal cohort. Methods We examined differences in SBP, DBP, insulin resistance (HOMA-IR), total cholesterol, HDL, LDL, triglycerides, CRP, and IL-6 at 3 years postpartum between women who delivered preterm (gestation<37 weeks; n=54) vs. term (≥37 weeks; n=751) using multivariable linear regression. We also assessed relations with BMI, weight change from pre-pregnancy, and waist circumference at 3 and 7 years postpartum. Results Median age at enrollment was 33.9 years (range: 16.4–44.9). After adjusting for age, race, pre-pregnancy BMI, parity, marital status, education, and SBP during early pregnancy, women with PTB had 3.99 (95% CI: 0.82, 7.16) mmHg higher SBP and 7.01 (1.54, 12.50) mg/dL lower HDL than those who delivered at term. The association with SBP was attenuated after accounting for hypertension before or during pregnancy (2.78 [−0.30, 5.87] mmHg). PTB was not related to other postpartum outcomes. Conclusions PTB is related to greater CVD risk by 3 years postpartum, as indicated by higher SBP and lower HDL. While these associations may be due to preexisting conditions exacerbated during pregnancy, PTB may flag high-risk women for more vigilant CVD monitoring and lifestyle interventions.

“…However, it is important that all nurses are skilled in performing manual BP measurement. Heinemann et al (2008) found that automated BP measurement devices can be used with some confidence to record systolic BP in most adults, but there was some variation observed when recording diastolic BP.…”

Rationale and key points This article aims to help nurses to measure blood pressure (BP) manually using an aneroid sphygmomanometer. ▶ BP measurement is an essential clinical skill, and nurses must be competent in performing this procedure and taking accurate readings. ▶ Nurses should be aware of manual BP measurement techniques and understand the patient and environmental factors that may result in inaccurate readings that could compromise patient care. ▶ Nurses should regularly undertake manual BP measurement to ensure they remain competent to perform the procedure. Reflective activity Clinical skills articles can help update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: 1. How reading this article will change your practice. 2. Further learning needs to extend your professional development. Subscribers can upload their reflective accounts at: rcni.com/portfolio .
