“…The Modelflow method enables us to monitor SV continuously in a noninvasive way. This method has undergone extensive validation in different subsets of patients [10, 11, 18, 19, 20, 21, 22]. Again, when calibration is not performed, relative changes compared to baseline values should be used, as was done in the present study.…”

Blood Pressure Response to Uncomplicated Hemodialysis: The Importance of Changes in Stroke Volume

et al. 2004

Background: The cause of blood pressure (BP) changes during uncomplicated hemodialysis (HD) has not been fully investigated. Controversy exists whether changes in BP result from changes in stroke volume (SV) or total peripheral resistance (TPR). Methods: We investigated 19 patients using continuous BP monitoring (Portapres^®) and subsequent Modelflow^® analysis, yielding continuous SV, cardiac output (CO) and TPR values. Blood volume (BV) monitoring was also performed. For each patient, the sensitivity index (SI) was calculated. The SI is the slope of the curve depicting the relationship between the systolic BP (SBP) response and the BV response. The patients were divided into two groups: group A had an SI >1 which means a decrease in SBP in response to BV change, and group B had an SI <1. In these patients, SBP remained stable despite a BV change. Results: Baseline characteristics and baseline values of all parameters were similar between the groups. In group A, SBP decreased by 25 ± 19 mm Hg and in group B the SBP increased by 5.0 ± 29 mm Hg (p < 0.05), while BV change was similar (10.6 ± 4.9 and 11.2 ± 4.2%, respectively). The difference in SBP response was caused by a different SV response (group A –44 ± 16% and group B –26 ± 18%, p = 0.04), while the TPR response was similar (71 ± 27% in group A vs. 59 ± 58% in group B). Conclusion: Patients responding with a BP decrease to BV reduction during uncomplicated HD differ in their SV response from patients with a stable BP.

“…The Finometer measures beat-to-beat blood pressure noninvasively using infrared plethysmography through a finger-cuff. Use of the Finometer and infrared plethysmography for monitoring blood pressure changes has been well established as a noninvasive measure of beat-to-beat blood pressure (10), has been extensively validated against intra-arterial blood pressure monitoring in older adults (11) and is validated for the assessment of arterial baroreflex function (12). The Finometer uses waveform filtering, level correction and an additional return-to-flow calibration to reconstruct brachial artery pressures (13).…”

Arterial stiffness and the response to carotid sinus massage in older adults

2010

Background and aims-Carotid sinus hypersensitivity (CSH) is a common cause of fainting and falls in the older adult population and is diagnosed by carotid sinus massage (CSM). Previous work has suggested that age-related stiffening of blood vessels reduces afferent input from the carotid sinus leading to central upregulation of the overall arterial baroreflex response. We examined the differences in arterial stiffness and baroreflex function in older adults at high cardiovascular risk (advanced age, Type 2 diabetes, hypertension and hyperlipidemia) with and without CSH.

Clin Invest Med 2009; 32 (3): E191-E198. AbstractPurpose: Neurocardiogenic syncope (formerly vasovagal) accounts for large numbers of falls in older adults and the mechanisms are poorly understood. This study examined the differences in baseline arterial baroreflex function in older adults with and without a neruocardiovascular response to orthostatic stress. Methods: Subjects were divided into two groups based on the presence (TT+ group) or absence (TT-group) of a neurocardiovascular response to upright tilting (70 degree head-up tilt for 10 minutes after 400 micrograms of sublingual nitroglycerin). A neurocardiovascular response was defined as presyncopal symptoms (lightheadedness) in association with at least a 30 mm Hg decrease in blood pressure. Before being divided into groups, baroreflex function was assessed using the spontaneous baroreflex method (baroreflex sensitivity, BRS). This method involves the analysis of "spontaneous" swings in blood pressure and heart rate that are mediated by the arterial baroreflexes. Results: 42 older adults (mean age 70.3±0.7 yr) were recruited, of which 18 were in the TT+ and 24 were in the TT-group. At baseline, the TT+ group demonstrated increased arterial baroreflex sensitivity in response to negative blood pressure sequences only (BRSdown, 11.2±1.9 vs. 7.3±1.0 ms/mm Hg, P=0.011). During tilt, the TT+ group demonstrated a much larger decrease in overall arterial baroreflex sensitivity than the TT-group (-6.8±1.2 vs. -3.2±0.9 ms/mm Hg, P=0.012). There was a negative correlation between BRSdown and length of tilt table test (r=-0.329, P=0.041) in the TT+ subjects. Conclusion: Older adults with neurocardiogenic syncope have exaggerated arterial baroreflex sensitivity at baseline.
