System identification of dynamic closed-loop cardiovascular control of total peripheral resistance by arterial and cardiopulmonary baroreceptors
… by control pathways, which influence either total peripheral resistance (Ra) or CO. Central control of Ra is achieved by a complex closed-loop negative feedback system composed of the arterial and the cardiopulmonary baroreflexes. The aims of the doctoral research presented in this thesis …

Moderating effect of a single aerobic exercise session on the cardiovascular response to a stressful procedure 45 minutes later
… control sessions, BP, HR, stroke volume (SV) and total peripheral resistance (TPR) were measured at baseline, during a pre-stressor anticipation period, and during the cold pressor test. stroke volume was measured with impedance cardiography and total peripheral resistance (TPR) was estimated. SBP …

Hemodynamic Responses to Isometric Contractions of the Finger Flexor and Leg Extensor Muscle Groups in Men 18-30 and 50-70 Years of Age
… heart rate, stroke volume, cardiac output, total peripheral resistance, systolic blood pressure, diastolic blood pressure, pulse pressure, and mean arterial pressure demonstrated significantly different responses to isometric exercise between the two age groups. Twenty-four, normal, healthy …

Predicting hyperlactatemia in the ICU
… as well as estimates of cardiac output and total peripheral resistance, we developed a variety of classifiers to place patients in risk categories based on serum lactate levels, a proxy for hypoperfusion and imminent circulatory shock.

Chronic Hypoxia and Cardiovascular Dysfunction in Sleep Apnea Syndrome
… ergometry. Mononuclear cells isolated from peripheral blood were utilized as reporter cells for measurement of VEGF, Akt-1, hypoxia inducible factor-1 alpha (HIF-1 alpha), and vascular endothelial growth factor receptor-2 (VEGFR2) gene expression by redundant oligonucleotide DNA microarray …

Acute hemodynamic responses to yoga exercise
… volume, cardiac work-load, cardiac output, and total peripheral resistance were measured using a finger plethysmograph during the yoga routine. Baseline measures of trunk flexibility (sit-and-reach scores and inclinometer measurements) and arterial stiffness (carotid-femoral pulse wave velocity) …

Controlling for Acute Caffeine Intake in Cardiovascular Reactivity Research
… left ventricular ejection time (LVET), and total peripheral resistance (TPR). Results support the adequacy of a six-hour abstention in controlling for caffeine-elicited CVR changes. The current study contributes to methodological endeavors in psychophysiology. Further investigations are …

Exercise testing in healthy haemodialysis patients
… while others developed systolic hypertension. Total blood volume, total body water and plasma renin activity were measured at rest. It was found that the 'normotensive' patients had normal body volumes and normal to high plasma renin activity, while the hypertensive subgroup had increased …

Signal processing approaches to analyzing patient cardiovascular state
… variables such as cardiac output (CO), total peripheral resistance (TPR), and PPV of patients who experience adverse outcomes to those who do not could help explain the link between adverse outcomes and intraoperative blood pressure variations. Data from patients undergoing …

The Effects of Rumination, Hostility, and Distraction on Cardiovascular Reactivity and Recovery From Anger Recall in Healthy Women
… (PEP), stroke index (SI), cardiac index (CI) and total peripheral resistance index (TPR) were collected from 80 healthy women (ages 18–30) during a 15-min baseline, a 3-min anger recall, and a 10-min recovery. Half of the participants were randomly assigned to a distraction condition (i.e. reading …

A forward model-based analysis of cardiovascular system identification methods
… activity and stochastic disturbances to total peripheral resistance (TPR) and heart rate representing, for example, autoregulation of local vascular beds and higher brain center activity. We demonstrated that this model emulates experimental data in terms of steady-state pulsatility, …

Modeling and monitoring of cardiovascular dynamics for patients in critical care
… for continuously tracking cardiac output and total peripheral resistance. This method exploits both intra-beat and inter-beat dynamics of arterial blood pressure, and incorporates a parametrized model of arterial compliance. We validated our method with animal data from laboratory experiments …

Continuous estimation of cardiac output and arterial resistance from arterial blood pressure using a third-order Windkessel model
… CO estimation algorithm which uses central and peripheral blood pressure waveforms to obtain reliable estimates of CO and the total peripheral resistance (TPR). We applied the estimation algorithm to a porcine data set.

Estimation of cardiovascular indices by analysis of the arterial blood pressure signal
… in stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR) by analysis of the arterial blood pressure (ABP) signal. The algorithms incorporate cardiovascular physiology within the framework of a generalized Windkessel model, which is a widely accepted cardiovascular model. …

Cardiovascular Reactivity in Posttraumatic Stress Disorder and Depression
… cardiography derived cardiac output (CO) and total peripheral resistance (TPR) were utilized to examine CVR during speech preparation/delivery and math tasks. Between-group effects were observed during speech preparation - specifically, lower DBP reactivity for the PTSD group compared to the …
