We are looking at the behavioral patterns of cardiovascular parameters such as HR, CO, TPR, MAP i.e. whether if they tend to increase, decrease or stay relatively constant. What defined methods do you know that can be used to describe such changes?
Are you looking for invasive or non-invasive methods and are you studying humans or is this in an experimental model?
There are of course several non-invasive methods to measure HR and MAP, depending on the species you are examining. For measurement of CO and subsequent calculation of TPR, invasive methods like conductance catheter, thermodilution and microspheres could be used. Non-invasive options are less accurate, but echocardiography is an option.
Thank you for your answer, Erik Dietrichs. I probably should have given more details in the question description. The experiment including 24 subjects on a short arm human centrifuge already took place and the data has been collected non-invasively via 3-lead-ECG and Finometer finger cuffs for continuous BP monitorization. My question was more regarding properly describing the behavior of the parameter curves. So far we have been experimenting with their slopes but we're looking for alternative methods.
HI - I see that you already have recorded the data you want to analyze. I assume you have the ecg, blood pressure and the finger pulse from the finapres. How often did you record this data, for what length of time (sec) each recording and do you have the pulsatile waveforms from the finger device. If so there are numerous ways you can get useful information from the data you have. Do you do pulse transit times from the ecg-qrs to the arrival of the pulse in the finger? You can get a lot of information regarding the status of the cardiodynamics from the pulsatile wave morphology. See the pulse transit time literature or look up our work on lymphedema and/or self applied tourniquets for the Navy Seal Teams. They both describe the parameters you can get regarding contractility, arterial/venous tone etc. Good luck.
