The aim of this work is to evaluate in different ventricular conditions the influence of joint mechanical ventilation (MV) and Hemopump assistance. To perform this study, we used a computer simulator of human cardiovascular system where the influence of MV was introduced changing thoracic pressure to positive values. The simulation confirmed that(More)
Left Ventricular Assist Device is used for recovery in patients with heart failure and is supposed to increase total cardiac output, systemic arterial pressure and to decrease left atrial pressure. Aim of our computer simulation was to assess the influence of Left Ventricular Assist Device (LVAD) on chosen haemodynamic parameters in the presence of(More)
Italy has a long tradition of telemedicine experiments that may be dated back to the early Seventies and currently many different telemedicine services are implemented in the country. Cardiology is the field of health care that currently gets the greatest benefits from telemedicine and it is also a very relevant field, since it is estimated that there are(More)
Patients assisted with left ventricular assist device (LVAD) may require prolonged mechanical ventilatory assistance secondary to postoperative respiratory failure. The goal of this work is the study of the interdependent effects LVAD like pulsatile catheter (PUCA) pump and mechanical ventilatory support or thoracic artificial lung (TAL), by the hemodynamic(More)
Computer simulation of cardiac haemodynamics represents an effective approach to the in vitro study of complex pathophysiological problems. Aim of our work was to reproduce, using a numerical simulator of the cardiovascular system, experimental waveforms of cardiac pressure and volumes, coronary blood flow and aortic pressure obtained in two anaesthetised(More)
In silico modeling of the cardiovascular system (CVS) can help both in understanding pharmacological or pathophysiological process and in providing information which could not be obtained by means of traditional clinical research methods due to practical or ethical reasons. In this work the numerical CVS was used to study the effect of interaction between(More)
Heart-lung interaction must be analyzed while assisting patients with severe respiratory problems or with heart failure in intensive care unit. Such patients can be assisted by mechanical ventilatory assistance or by thoracic artificial lung. This paper presents an e-Learning environment aiming at teaching the interaction of cardiovascular and lung systems(More)
