System identification of dynamic closed-loop cardiovascular control of total peripheral resistance by arterial and cardiopulmonary baroreceptors
… 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 were: 1) …

Moderating effect of a single aerobic exercise session on the cardiovascular response to a stressful procedure 45 minutes later
… 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 was …

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 males, …

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.

Using impedance cardiography to examine changes in hemodynamic parameters during heart rate biofeedback
… HR, systolic blood pressure, stroke volume, and peripheral-resistance responses to the post-training compared to the pre-training videogame. Overall, these results suggest that HR feedback training is an effective method for reducing cardiovascular responding to a stressor.

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 …

Cardiovascular components of organophosphorus-induced delayed neuropathy
… weight and the level of pcO2 and an increase in peripheral resistance were observed prior to evidence of clinical signs of OPIDN. When maximal signs of OPIDN were present, brain NTE and plasma cholinesterase were at control levels but brain cholinesterase was significantly increased. Significant …

Acute hemodynamic responses to yoga exercise
… 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) were …

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 crucial in …

Exercise testing in healthy haemodialysis patients
… hypertension with a high calculated total peripheral resistance. On the second occasion his cardiac output response fell within the normal range, his blood pressure was lower but not normal and his calculated total peripheral resistance was even higher than before. Thus, the blood pressure …

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 cardiothoracic …

The Effects of Rumination, Hostility, and Distraction on Cardiovascular Reactivity and Recovery From Anger Recall in Healthy Women
… 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 …

Cognitive functioning, cardiovascular activity, and state affect in men with and without a parental history of hypertension
… sample. More specifically, decreased baseline peripheral resistance and increased baseline cardiac activity were related to better test performance. During testing, only increased cardiac reactivity was related to better test performance. The present results suggest that parental history group …

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, limiting …

Modeling and monitoring of cardiovascular dynamics for patients in critical care
… 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 and …

Does altering brachial artery tone with lower-body negative pressure and flow-mediated dilation affect arterial stiffness?
… coefficient (ICC). While heart rate (P<0.01) and peripheral resistance increased during LBNP (P<0.05), forearm blood flow and pulse pressure decreased (P<0.01). hi terms of mechanical properties, vessel diameters decreased (P<0.05), but both compliance and distensibility were not changed. On the …

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.
