Perfusion Occlusion System for IPL-2

Perfusion Occlusion System for IPL-2

The Perfusion Occlusion System for IPL-2 allow double occlusion.

Allows double occlusion for:

  • Measurement of segmental vascular resistances (precapillary and postcapillary resistance)
  • Measurement of microvascular pressure 

Allows individual arterial and venous occlusion for:

  • Determination of large and small artery resistances
  • Determination of large  and small vein resistances
  • Determination of vascular compliance

The Double Occlusion System for the isolated Lung size 2 (IPL-2) has been designed to simultaneously pinch off the inflow and outflow to the lung (Double Occlusion) using two magnet pinch valves. The Inflow is the tube to the pulmonary artery, the Outflow is the tube of the cannula in the left atrium.

The Double Occlusion for Isolated Lungs is a special technique in order to prove evidence about the pulmonary vascular resistance or respectively segmental vascular resistance. For this purpose the pulmonary arterial inflow and venous outflow is simultaneously stopped using the two magnet valves. In parallel the pulmonary arterial pressure (Pa) and venous pressure (Pv) are measured.

After a period of a few seconds the two pressures equalize. The resulting ”clamp” pressure (Pc) is measured.

The segmental vascular Resistance is a result of:

Rpre = (Pa - Pc) / Flow

Rpost = (Pc - Pv) / Flow

The flow rate value before the Occlusion is used as Flow.

  • Stand 
  • Two pinch valves
  • Controller for perfusion occlusion 
  • The peristaltic pump requires external ON/OFF control
