| Simulator
Performance |
| |
| The
simulator can reproduce a wide range of physiological flows
conditions: debt can vary from 2 to 7 l/mn, cardiac frequency
from 40 to 120 beats/mn We represented below signals recorded
by the simulator. These flows have an average debt of 3 l/mn
at 72 beats/mn. The higher graphs are measured in a "normal"
case, that is to say the case of a young person having a mechanical
prosthesis. The lower graphs represent a case of atrial fibrillation
(no atrial contraction) in the same conditions of an average
cardiac debt. |

| The
mitral flow (blue) presents a different shape, depending on
the testing conditions. This will have, as will be shown in
the next paragraph, a significant influence on the functioning
of the valvular prosthesis. It should be noticed that the pressure
conditions are similar in both cases, which guarantee similar
charge conditions. |
