Selected AbstractsUse of an Automated Device for External Chest Compressions by First-aid Workers Unfamiliar With the Device: A Step Toward Public Access?ACADEMIC EMERGENCY MEDICINE, Issue 12 2009Frédéric Lapostolle MD Abstract Objective:, The objective was to establish the feasibility of using an automated external chest compression (ECC) device among first-aid workers unfamiliar with the device. Methods:, Eighty first-aid workers unfamiliar with the Autopulse ECC device were randomized into three groups. Group 1 was given two explanatory illustrations on device use. Group 2 was given four explanatory illustrations. Group 3 was shown a 5-minute video on the placement and use of the device and allowed to handle the device for 5 minutes. The time taken to place and start the device on a mannequin was recorded. Results:, There was no significant difference among the three groups with regard to age, sex ratio, experience, and time elapsed since their last training session. No mistakes in device placement were made by any of the groups. All 80 participants started ECC in less than 160 seconds. There was no significant difference between Groups 1 and 2 in time taken to place or start the device (medians and 25,75 percentiles = 72 [54,112] vs. 86 [46,130] seconds and 154 [103,183] vs. 156 [120,197] seconds, respectively). However, Group 3 first-aid workers obtained significantly better results (19 [16,26] seconds to place and 48 [40,65] seconds to start; p<0.0001). Conclusions:, An automated ECC device can be rapidly placed and used by first-aid workers unfamiliar with the device. In the light of these results, use of the device by the general public can be envisaged. [source] Characterizing blood pressure control in individuals with Type 2 diabetes: the relationship between clinic and self-monitored blood pressureDIABETIC MEDICINE, Issue 9 2003R. S. Mazze Abstract Aims To determine the relationship between blood pressure (BP) measurement in the clinic and self-monitored blood pressure (SMBP); and to evaluate the accuracy of self-reported data in patients with Type 2 diabetes treated intensively for hypertension. Methods Seventy subjects had baseline and 1-week follow-up clinic BP measured using an Omron 907® automated device. During a contemporaneous 14-day period these subjects measured their BP at least four times each day using an Omron IC® semiautomatic portable monitor which, unknown to them, contained an onboard memory capable of storing BP with corresponding time and date. Results There was no significant difference between mean clinic and mean self-monitored BP. Correlations between clinic BP and SMBP were r = 0.61 (P < 0.0001) for systolic BP and r = 0.69 (P < 0.0001) for diastolic BP. Clinic BP classified 56 subjects as uncontrolled hypertension (BP , 130/80 mmHg, adjusted for diabetes) and 14 subjects as controlled hypertension. Using World Health Organization-International Society of Hypertension criteria for SMBP (, 125/75 mmHg), 55 cases of clinic classified uncontrolled hypertension were confirmed, resulting in 98% sensitivity. Clinic and SMBP agreed in one case of controlled hypertension, resulting in 7% specificity. For all subjects, the median percent of values exceeding SMBP criteria for controlled hypertension was systolic 92% and diastolic 70%. Self-reporting precision averaged 89 ± 10% (range 45,100%); under-reporting was 25 ± 16% (ranging from 0 to 56%) and over-reporting was 12 ± 15% (ranging from 0 to 46%). The overall logbook mean was not significantly different from the downloaded data from the Omron IC® monitors. Conclusions SMBP was able to identify 13 patients with uncontrolled hypertension who, by clinic BP measurement, had been classified as controlled.

Ochsenbein-Kölble Objective To generate reliable new reference ranges for pregnancy blood pressure from a large population. Design A prospective cross sectional study. Setting Obstetric outpatient clinic, Zurich University Hospital. Sample Accurately dateable singleton pregnancies (Caucasian: n= 3234; Asian [predominantly from Sri Lanka, Thailand and the Philippines]: n= 577; Black n= 212). Methods Between January 1996 and February 2000 blood pressure was determined in 4023 pregnant women using an oscillometric automated device (Dinamap) according to British Hypertension Society recommendations. Women receiving antihypertensive medication were excluded. Main outcome measure Blood pressure. Results Only the means of duplicate measures at the booking visit (5,42 weeks) were used in the analysis. Mean blood pressure decreased from early to mid pregnancy before increasing to levels 4 mmHg higher at term than in early pregnancy. Values >130/80 and <90/50 mmHg were above the 95th and below the 5th centiles, respectively. Parity, age and body mass index were significant determinants in Caucasians. Blood pressure was slightly lower in Asians and Blacks. Conclusions The current World Health Organisation definition of high diastolic blood pressure (,90 mmHg on two occasions) reflects values >2 standard deviations from the mean. This may be too conservative as threshold for detecting women at risk of pre-eclampsia. Further studies are required to determine the prognostic implications of gestational values ,95th centile (,130/80 mmHg) and ,5th centile (,90/50 mmHg). [source] A Review of Nursing Research on Blood PressureJOURNAL OF NURSING SCHOLARSHIP, Issue 4 2002Sue Ann Thomas Purpose: To provide this second 10-year review of nursing research on blood pressure (BP) and to focus attention on incorporating biopsychosocial factors affecting BP in nursing research. Organizing Construct: Blood pressure is a dynamic, multidimensional, cardiovascular indicator of a person's state rather than a one-dimensional static measurement. Methods: This 10-year literature review 1990,1999 included 54 nursing research articles with BP as an outcome measure. Four nursing research journals were reviewed to identify all nurse-authored articles investigating BP as an outcome variable in adult populations. Inclusion of individual characteristics, environmental factors, dynamic nature of blood pressure, and interpersonal aspects of blood pressure were assessed for each article. Findings: Age, gender, and health status were mentioned consistently in both decades. Reporting of socioeconomic, occupational, educational, activity, and martial status remained low. Descriptions of environments increased, and automated devices were the most common method for BP assessment. Less than half of the articles included a description of the person measuring the BP. Measurement of BP under multiple conditions increased, but measurement within conditions did not. Conclusions: Advances in technology and data analysis have increased knowledge of the dynamic nature of BP, but recognition of the complex nature of BP has not progressed rapidly over the last 2 decades.
