Abstract:
A method for measuring hemodynamics of an experimental animal enabling repeated measurements, the method comprising the following steps:(i) ligating at least two parts of an artery, between which a part to be incised is located, of the experimental animal, the parts comprising at least one proximal ligated part and at least one distal ligated part, and then incising a part between the ligated parts; (ii) inserting through the incised part a blood pressure-volume simultaneously measuring catheter provided with multiple conductance electrodes and at least one pressure sensor; (iii) loosening the proximal ligated part so as to allow an insertion of the catheter and not to cause bleeding in the opened part; (iv) further inserting the catheter so as to introduce the multiple conductance electrodes and the pressure sensor(s) into the heart ventricle; and (v) simultaneously measuring pressure and volume of the heart.
