Editor's Notes
- start delay: delay before first inflation/deflation cycle begins cycle interval: time interval between two measurements within the series: This is a value between 2 and 16 min (“c” on the drawing below) trains interval: interval between two series of measurements: between 3 min and several hours (“d” on the drawing below) high pressure: maximum inflation value for tail cuff pressure (occlusion pressure, “f” on the drawing below). This value is limited at 250mmHg. low pressure: value of the tail cuff pressure: when this value is reached during the deflation the electrovalve operation stops (“e” on the drawing below). Please note that the low pressure is also the basal pressure (the cuff pressure between inflation/deflation cycles) - it should therefore be set so as not to make the subject uncomfortable.
- I don't think this graph adds much to the presentation. The resolution is too small to see anything of significance- scientists in the audience will be scrutinizing the graph and not paying attention to what you are saying. I can't make out the scales at all. It also looks to me like the increase in heart rate is not reflected in a change in blood pressure- which you would expect to see- or that the corresponding points are missing- both don't look good for OPT.
- These would look much better if we could re-graph them in sigmaplot (the program I used for the dog data in the previous pictures). If you can send me the excel from the results file I can graph it for you and send it back. I also think we should graph the heart rate from the ecg against the heart rate from the NIBP- to show the audience that they are similar or the same (hopefully) or add some activity data.
