“…This device satisWed the requirements on precision and safety set by the Association for the Advancement of Medical Instrumentation (ANSI/AAMI SP10 protocol) (De GreeV et al 2008). All participants were instructed not to move or talk during the blood pressure measurements and seated with the arm supported by the armrest of the chair at the approximate heart level.…”

The present study examined the effects of physical and mental workload during computer tasks on muscle activity and physiological measures. Activity in cervical postural muscles and distal forearm muscles, heart rate and blood pressure were compared among three tasks and rest periods of 15 min each in an experimental study design. Fourteen healthy pain-free adults participated (7 males, mean age = 23.2 ± 3.0 years) and the tasks were: (1) copy-typing ("typing"), (2) typing at progressively faster speed ("pacing"), (3) mental arithmetic plus fast typing ("subtraction"). Typing task was performed first, followed by the other two tasks in a random order. Median muscle activity (50th percentile) was examined in 5-min intervals during each task and each rest period, and statistically significant differences in the "time" factor (within task) and time × task factors was found in bilateral cervical erector spinae and upper trapezius muscles. In contrast, distal forearm muscle activity did not show any significant differences among three tasks. All muscles showed reduced activity to about the baseline level within first 5 min of the rest periods. Heart rate and blood pressure showed significant differences during tasks compared to baseline, and diastolic pressure was significantly higher in the subtraction than pacing task. The results suggest that cervical postural muscles had higher reactivity than forearm muscles to high mental workload tasks, and cervical muscles were also more reactive to tasks with high physical demand compared to high mental workload. Heart rate and blood pressure seemed to respond similarly to high physical and mental workloads.

“…The same trend was found when only devices that have been successfully validated in individuals with sinus rhythm were included [15][16][17]20,21], with pooled SBP difference of 0.6 mmHg (95% CI À1.1, 2.4) and DBP difference of 4.1 mmHg (95% CI À1.0, 7.3). The respective pooled BP differences from validation studies in individuals with sinus rhythm [22][23][24][25][26][27][28] using the successfully validated devices included in the analysis (Table 1) were À1.1 mmHg (95% CI À1.7, À0.5) for SBP and À1.5 mmHg (95% CI À1.9, À1.0) for DBP. Nine of the 12 validation studies reported absolute differences between automated and auscultatory BP measurement ( Table 2).…”

“…For the comparison of the two methods, sequential BP measurements were used in nine validations and simultaneous in three (two in opposite arms and one in the same arm). From the test devices included in this analysis, six were successfully validated in individuals with sinus rhythm [22][23][24][25][26][27][28]. Pooled BP differences were also calculated from these validation studies in individuals with sinus rhythm.…”

There is limited evidence and significant heterogeneity in the studies that validated automated blood pressure monitors in atrial fibrillation. These monitors appear to be accurate in measuring SBP but not DBP. Given that atrial fibrillation is common in the elderly, in whom systolic hypertension is more common and important than diastolic hypertension, automated monitors appear to be appropriate for self-home but not for office measurement.

“…After a 5 min rest, each patient had six BP measurements taken consecutively in a sitting position in the same arm with a validated device (Tensoval Duo Control; Hartmann, Heidenheim, Germany [11]) in two random phases: one phase consisting of three readings without waiting time between readings [immediate readings (IR)] and another phase of three readings with a 1 min interval between readings [waiting readings (WR)]. The cuff for obese patients was used when necessary.…”
