CS 100 Intra-Aortic Balloon Pump. It supports the heart's left ventricle by increasing coronary perfusion and reducing left ventricular work. Coronary perfusion is increased by augmenting blood pressure during the diastolic phase of the cardiac cycle. This increase in aortic pressure promotes more blood flow through the coronary arteries. Left ventricular work is reduced by decreasing aortic end diastolic pressure and reducing resistance to ventricular ejection, resulting in a decrease in blood pressure during the systolic phase of the cardiac cycle.

False blood back detection alarm and the ingress of fluids into the IABP affecting various electronic circuit boards could potentially prevent initiation or continuation of therapy.

Maquet/Getinge recommends that users review the water condensation procedure (CS100/CS100i and CS300 IABP Operating Instructions section 3.4.1) to reduce the potential for condensation accumulation. In the event the IABP fails to successfully cycle and clear the alarm, remove the IABP from service and contact your local Maquet/Getinge Sales & Service Office. o For Fluid Ingression - Until the service is performed, Maquet/Getinge recommends customers review of the CS100/CS100i and CS300 IABP Operating instructions regarding cautions on placement of fluids and hanging of bags of fluid over the IABP. All facilities will be contacted by a representative of the Maquet/Getinge Service Team to schedule on-site service of your CS100/CS100i or CS300 IABP.
