Evaluation of Antithrombogenic Thermodilution Catheter

Journal of Biomaterials Applications, 1989
In order to prevent the complications accompanied with pulmo nary-artery (Swan-Ganz) catheterization, we have developed an antithrombo genic coating, tradenamed Anthron®.* Anthron-coated thermodilution cath eters show excellent antithrombogenicity due to continuous release of heparin from its surface to the blood stream in animal experiments.

Thermodilution Measurement of Lung Water

Clinics in Chest Medicine, 1985
The detection and measurement of pulmonary edema by the thermal-dye method appears to be accurate and reproducible under specified laboratory conditions. The ETV, which represents the difference in distribution volumes of the diffusible (thermal) indicator and the intravascular (green dye) indicator, should closely estimate the ELM (ETV = 0.984 ELM ...

Cardiac Output by Thermodilution

JAMA: The Journal of the American Medical Association, 1985
To the Editor.— It has been estimated that between 1 and 2 million pulmonary artery catheters were inserted for hemodynamic monitoring in the last decade. 1 The prevalence of the procedure has increased substantially over the past few years. It is therefore of interest that the methodology of a clinical hemodynamic measurement, cardiac output by ...

Loss of indicator in the thermodilution technique

Catheterization and Cardiovascular Diagnosis, 1978
AbstractThe use of a second thermistor for detecting the injectate temperature in the extravascular segment of a standard right heart thermodilution catheter is described. Experiments with chilled (0°C) indicator show that the temperature of the injectate as it enters the catheter is always greater than zero and that it depends on time and the gradient

Simplification of continuous intracoronary thermodilution

EuroIntervention
Continuous intracoronary thermodilution with saline allows for the accurate measurement of volumetric blood flow (Q) and absolute microvascular resistance (Rμ). However, this requires repositioning of the temperature sensor by the operator to measure the entry temperature of the saline infusate, denoted as Ti.We evaluated whether Ti could be predicted ...

Near continuous cardiac output by thermodilution.

Journal of clinical monitoring, 1997
A new thermodilution method for frequent (near continuous) estimation of cardiac output, without manual injection of fluid into the blood, was tested. The method utilizes a pulmonary artery catheter equipped with a fluid filled heat exchanger. The technique is based on cyclic cooling of the blood in the right atrium and measurement of the temperature ...

A thermodilution method for quantification of bidirectional shunts

Computers and Biomedical Research, 1979
Abstract A method for measurement of bidirectional cardiovascular shunt fractions from single indicator dilution curves is presented. Linear system models corresponding to four basic shunt configurations are devised to represent the indicator dilution response of the cardiopulmonary circulation.

Cardiac Output by Thermodilution-Reply

JAMA: The Journal of the American Medical Association, 1985
In Reply.— We thank Dr McIntyre for his thoughtful letter in which he states that the importance of the respiratory effect on the measurement of cardiac output appears to have now been settled by our recent article. Dr McIntyre has briefly reviewed several of the critical factors influencing pulmonary interactions with cardiac output.

La thermodilution transpulmonaire

2007
Chez les patients porteurs d’un catheter veineux central et d’un catheter arteriel dote d’une thermistance, la thermodilution transpulmonaire est une technique qui permet la mesure de nombreux parametres cardio-respiratoires. Apres injection par voie veineuse centrale d’un indicateur thermique (serum physiologique superieur a 24 °C), la thermistance du

Measurement of Cardiac Output by Thermodilution

New England Journal of Medicine, 1975
THE functional assessment of myocardial performance includes a measurement of cardiac output. Such precise diagnostic information is particularly valuable in patients with cardiac disease who are u...
