CATHIS® RHC Simulator

Training on the CATHIS® RHC Simulator is supported by a selection of predefined cases with different clinical pictures and symptoms. For the individual training needs, further cases can be defined.

The equipment of the hardware allows the use of different instruments, such as standard catheters, Swan-Ganz right heart catheters with different lumens and thermodilution.

Based on the simulation, it is also possible to uniformly define measurement criteria as the standard for the right-heart catheter examination, according to which, as a rule, measurements must take place in defined areas. Depending on requirements, it is possible to describe concourse of circumstances that are rare in reality but important for diagnostics.

In the simulation, as in reality, the essential measurements are performed via a catheter:

  • Venous pressures in the right atrium and ventricle, in the pulmonary artery.
  • Determination of the pulmonary closure pressure (wedge pressure). These measurements are possible during the simulation at any point and at any time.
  • Hemodynamics with cardiac output via thermodilution. These values ​​can be used to calculate resistances such as pulmonary vascular resistance, pulmonary arteriolar resistance and total vascular resistance.
  • Measuring the oxygen saturation of the blood; This is possible during the simulation at any point and at any time.

An essential feature of the CATHIS-RHC simulation is the instrument guidance under image control. Thus, the catheter can be introduced under observation, i.e. its position can be selectively controlled.

The fluoroscopy is especially useful in the training, because it shows the movement and position of the catheter in the atrium, in the ventricle or the pulmonary artery. This x-ray image promotes the understanding of the relationship between anatomy and the measured pressure values.

This provides especially benefits for less experienced physicians and trainees as well as nursing staff, because the simulation provides valuable insights into the process of a right-heart catheter intervention.
