Errors in the measurement of cardiac output by thermodilution [PDF]

Canadian Journal of Anaesthesia, 1993
Cardiac output (CO) determination by thermodilution, which was introduced by Fegler in 1954, has gained wide acceptance in clinical medicine and animal experiments because it has several advantages over other methods with respect to simplicity, accuracy, reproducibility, repeated measurements at short intervals, and because there is no need for blood ...

The golden ratio in the pulmonary circulation in patients with heart failure and cardiogenic shock

Physiological Reports, Volume 13, Issue 7, April 2025.
Stroke volume is a determinant of both mPAP (left wireframe plot) and PP (right surface plot). Mean pulmonary artery pressure changes with SV with a coefficient of (PVR/t, where t = cardiac interval). The mPAP plot is based on a PVR of 4.2WU (or 0.252 mmHg/mL.s) at cardiac intervals from 400 to 1000 ms and PAWP of 29 mmHg.

Quantification of left ventricular ejection fraction and cardiac output using a novel semi-automated echocardiographic method: a prospective observational study in coronary artery bypass patients

BMC Anesthesiology, 2023
Background Echocardiographic quantification of ejection fraction (EF) by manual endocardial tracing requires training, is time-consuming and potentially user-dependent, whereas determination of cardiac output by pulmonary artery catheterization (PAC) is ...

Anthracycline-Induced Cardiotoxicity: Cardiac Monitoring by Continuous Wave-Doppler Ultrasound Cardiac Output Monitoring and Correlation to Echocardiography [PDF]

, 2012
Background: Anthracyclines are agents with a well-known cardiotoxicity. The study sought to evaluate the hemodynamic response to an anthracycline using real-time continuous-wave (CW)-Doppler ultrasound cardiac output monitoring (USCOM) and ...

Dasatinib‐Induced Pulmonary Arterial Hypertension in Chronic Myeloid Leukaemia: A Case Report and Literature Review

Respirology Case Reports, Volume 13, Issue 3, March 2025.
Dasatinib, a second‐generation tyrosine kinase inhibitor used for treating chronic myeloid leukaemia (CML), is associated with rare but significant adverse effects, including pulmonary arterial hypertension. We present the case of a 55‐year‐old female with CML who developed severe pre‐capillary pulmonary hypertension after prolonged dasatinib use ...

Preejection period as a sympathetic activity index: a role of confounding factors [PDF]

, 2017
In previous studies, one of the systolic time intervals - preejection period (PEP) - was used as an index of sympathetic activity reflecting the cardiac contractility.

Haemodynamic effects of intra‐aortic balloon pumps stratified by baseline pulmonary artery pulsatility index

ESC Heart Failure, Volume 12, Issue 1, Page 316-325, February 2025.
Abstract Aims Intra‐aortic balloon pump (IABP) devices are commonly used in patients with heart failure related cardiogenic shock (HF‐CS), including those with out‐of‐proportion right ventricular (RV) dysfunction. Pulmonary artery pulsatility index (PAPi) is a haemodynamic surrogate for RV performance. We aimed to assess short‐term haemodynamic changes
