BACKGROUND AND OBJECTIVES To analyse the precision of transpulmonary thermodilution from the PiCCO technique (Pulsion Medical System, Munich, Germany) in everyday intensive care practice in order to ascertain the minimum number of measurements necessary for scientific precision. METHODS An observational study in the medical-surgical ICU of a teaching(More)
BACKGROUND/AIM There is a limited number of methods to measure blood flow velocity in small veins. A cheap and simple new videomicroscopic method developed in our laboratories is described in the paper. METHODS A stretch of the saphenous vein of the rat was exposed by careful micropreparation on the thigh of anesthetized animals. Bolus amount (approx. 5(More)
Light-induced fluorescence decay was examined during the greening of control and lincomycintreated maize (Zea mays L.) leaves. Assuming that this decay to a first approximation is the result of two parallel first-order reactions, the fluorescence induction curves were linearized on the logarithm plot and the parameters were determined. The variable(More)
In the present paper, an attempt was made to find waveform-derived variables that would be useful for a more precise diagnosis of hypovolemia. In attempting this, arterial blood pressure graphs of 18 hypovolemic postoperative patients were analysed using a discrete Fourier transform. Using a paired samples t-test, the amplitude of the first harmonic (A1) is(More)
AIM Diagnosing hypovolemia is not a trivial task. Hypovolemia itself has several physical signs, but their specificity and sensitivity is limited, even using sophisticated monitoring techniques. However, diagnosing hypovolemia is crucial in critically ill patients to avoid worse outcomes. The aim of this paper is to provide methods for better estimation of(More)
