The influence of mean pulmonary arterial pressure (mean P(pa)) on dynamic (C(d)) and pseudostatic compliance (C(ps)) of the pulmonary artery was studied at a constant and a changing heart rate. C(d) is the change in cross-sectional area (CSA) relative to the change in P(pa) throughout a heart cycle. C(pa) is the change in mean CSA relative to...article 1998

(author), TNO Biomedical Instrumentation (author)Application of the Stewart-Hamilton equation in the thermodilution technique requires flow to be constant. In patients in whom ventilation of the lungs is controlled, flow modulations may occur leading to large errors in the estimation of mean cardiac output. Methods: To eliminate these errors, a modified equation was developed. The resulting...article 1996

(author), Technisch Physische Dienst TNO - TH (author)The application of the thermodilution method in conditions associated with variations in blood flow implies a misuse of the Stewart Hamilton equation. Therefore, we studied the reliability of the thermodilution method for the estimation of mean cardiac output (CO) during mechanical ventilation in patients (n = 9). Variation of the injection...article 1990
