EleMarsh Mode

ENG | 中文 | 日本語

EleMarsh mode makes the infusion behaviour of the Marsh model behave like Eleveld model, thereby improving its precision for patients at extremes of BMI and age.

This is achieved through adjusting the Marsh input weight using our novel algorithm. [Ref]

Step by step guide to using the EleMarsh mode:

(1) Enter patient details and desired Ce target

(2) EleMarsh generates the Adjusted Body Weight and Induction CpT

(3) Use the Adjusted Body Weight as the Marsh input weight on your TCI pump

(4) Use the Induction CpT as your initial CpT setting. As soon as the bolus is given, drop the CpT down to your desired CeT. The Marsh model on your pump will now mimic the behaviour of the Eleveld model.
