We investigated whether sleep quantity and quality were related to 24-hour ambulatory blood pressure and cardiovascular reactivity in children. We studied term-born, healthy 8.0-year olds (SD: 1.4 years) without sleep-disordered breathing (231 and 265 children provided valid data for analyses of ambulatory blood pressure and cardiovascular reactivity, respectively). Sleep was registered with an...

Increased arterial stiffness is an independent predictor of cardiovascular disease and mortality in middle-aged and older adults. However, limited data are available regarding the relationship of arterial stiffness in young adults with risk factors measured in childhood, adulthood, or as a cumulative burden from childhood to adulthood. This aspect was examined in a sample of 835 black and white...

OBJECTIVE Arterial hypertension is the most frequently observed vascular risk factor. Physical and rehabilitative interventions may affect arterial blood pressure. The frequency of hypertensive patients in an outpatient clinic of physical medicine is unknown. DESIGN Prospective data collection. PATIENTS Overall, 3,826 patients admitted to the outpatient clinic for physical and rehabilitativ...

BACKGROUND Monitoring cardiovascular function in acutely ill patients in the emergency department (ED) is of paramount importance. Arterial pressure (AP) is usually monitored using intermittent oscillometric measurements with an upper arm cuff. The vascular unloading technique (VUT) allows continuous noninvasive AP monitoring. In this study, we compare continuous AP measurements obtained by VUT...

Venous access and fluid therapy should still be considered to be essential elements of pre-hospital advanced life support (ALS) in the critically injured patient. Initiation of fluid therapy should be based on a clinical assessment, most importantly the presence, or otherwise, of a radial pulse. The goal in penetrating injury is to avoid hypovolaemic cardiac arrest during transport, but at the ...

Radial artery tonometry provides continuous measurement of non-invasive arterial pressure (CNAP) by a sensor positioned above the radial artery. An inflatable upper arm cuff enables intermittent oscillometric calibration. CNAP was compared with invasive radial artery pressure recordings from the opposite wrist in 22 high-risk surgical patients with an inter-arm oscillometric mean arterial press...

BACKGROUND AND OBJECTIVES Since 1903, blood pressure has been noninvasively monitored (NIBP), either with manual sphygmomanometer or automated noninvasive devices. One NIBP measurement problem is the considerable variance in blood pressure data, both within and between available techniques. The oscillometric method for NIBP monitoring evaluates blood pressure during cuff deflation. Difficulties...

Blood pressure variability based on office measurement predicts outcome in selected patients. We explored whether novel indices of blood pressure variability derived from the self-measured home blood pressure predicted outcome in a general population. We monitored mortality and stroke in 2421 Ohasama residents (Iwate Prefecture, Japan). At enrollment (1988-1995), participants (mean age, 58.6 ye...

Measurement of arterial blood pressure is an important vital sign for monitoring the circulation. However, up to now no instrument has been available that enables the measurement of blood pressure underwater. The present paper details a novel, oscillometric, automatic digital blood pressure (BP) measurement device especially designed for this purpose. It consists mainly of analogue and digital ...
