The hemodynamics of counterpulsation

The Journal of Thoracic and Cardiovascular Surgery, 1966
Summary and conclusions 1. Synchronized counterpulsation was applied to two groups of 9 dogs with the use of a new fluid-coupled pulse generator. Multiple measurements were made of central (cardiac) and peripheral hemodynamics. 2. The counterpulsation pump performance was superior to pneumatically coupled systems previously studied.

Machine learning-enabled estimation of cardiac output from peripheral waveforms is independent of blood pressure measurement location in an in silico population

Scientific Reports
Monitoring of cardiac output (CO) is a mainstay of hemodynamic management in the acutely or critically ill patient. Invasive determination of CO using thermodilution, albeit regarded as the gold standard, is cumbersome and bears risks inherent to ...

Cognition and Hemodynamics [PDF]

Current Cardiovascular Risk Reports, 2012
The relationship between cerebral hemodynamics and cognitive performance has increasingly become recognized as a major challenge in clinical practice for older adults. Both diabetes and hypertension worsen brain perfusion and are major risk factors for cerebrovascular disease, stroke and dementia.

Sex differences in vascular hemodynamics in middle-aged and older adults

, 2021
Access to thesis permanently restricted to Ball State community only.Cardiovascular disease-related (CVD) mortality with older age is in part attributable to altered vascular hemodynamics including increased central and peripheral blood pressure (BP ...

Safety and Effectiveness of a High‐Dose, Tailored Tissue Plasminogen Activator Therapy Protocol: A Joint Pediatric Hematology and Cardiac ICU Quality Improvement Initiative Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Novel theory and potential applications of central diastolic pressure decay time constant

Scientific Reports
Central aortic diastolic pressure decay time constant ( $${\uptau }$$ τ ) is according to the two-element Windkessel model equal to the product of total peripheral resistance ( $$R$$ R ) times total arterial compliance ( $$C$$ C ). As such, it is related
