Simulator Data Recordings:
In this section of the website, we'll explore the use of the simulator (and data recording in particular) in helping us to understand the behaviour of the patient and of ECMO systems when confronted with changing conditions.
The data recorder is able to record up to thirty variables simultaneously at a user-nominated frequency of between 5 and 300 seconds. It should be noted that the data recorder itself does not create any graphical output and only generates time-indexed Microsoft 'Excel' files. All the graphs shown below are the result of 'post-hoc' analysis of such files.
The examples which are currently available are:
- VV ECMO: The effect of initiation of VV ECMO on PaO2.
- VV ECMO: The effect of an increase in cardiac output on arterial PO2.
- VV ECMO: The effect of a reduction in cardiac output on arterial PO2.
- VV ECMO: The effect of return cannula size on system behaviour.
- VV ECMO: The effect of an increase in gas flow rate on PaCO2.
- VV ECMO: The effect of 'Sweep Gas' Flow rate on PaCO2.
- VV ECMO: The effect of an increase in ECMO blood flow rate on PaO2.
- VV ECMO: The effect of ECMO blood flow rate on PaO2.
- VV ECMO: The effect of cooling on PaO2.
- VV ECMO: The effect of using air rather than oxygen.
- VV ECMO: The effect of variation in haematocrit on PaO2.
- VA ECMO: The effect of FiO2 change on PaO2.
- VA ECMO: The effect of afterload on pump flow.
- VA ECMO: The effect of disconnection of gas supply.
- VA ECMO: The effect of blood flow on the rate of oxygen transfer.
- VA ECMO: Oxygen transfer. Comparison with real data.
- VA ECMO: Effect of VO2 on PaO2.
- The relationship between Qs/Qt and Cardiac Output.
- Patient: The effect of temperature on metabolic rate.
- Patient: The ventilatory response to hypoxia.
- Patient: The effect of cardiac output on SaO2 when Qs/Qt remains constant.
- Patient: The effect of Adrenalin.
