A novel clinical data acquisition device: Towards real time cardiovascular modelling in the ICU

Patient specific cardiovascular system models have the potential to provide far greater insights into patient conditions than is currently possible in the intensive care unit (ICU). Access to haemodynamic data is imperative for the introduction and validation of these models for model-based care in the ICU. However, current bedside machines are proprietary systems and do not allow access to any data without potentially prohibitive cost, creating a barrier to research and advancements in bedside care. This work presents a novel, low-cost data capture system which allows real time capture of haemodynamic measurements, as well as fluid infusion rates in the ICU. The system consists of an Arduino controlled data capture unit, an adaptor for connecting to existing bedside pressure sensors, and a Python based application which displays and records data sent from the data capture system over a USB serial connection. The total system is highly customizable if needed, and costs a total of NZ$200.
