I did a test and the graph presented the following situation: the transaortic line went down from positive to negative and before another test starts it went up from negative to positive. what would be the problem so that this does not happen again?
Hi Leonardo, The trans-aortic line is the (ventricle pressure)- (aortic pressure). If the valves are setup backwards or if the incorrect transducers are hooked up, you can defiantly get this result. If you still have the ACQ. file you can send it to us at firstname.lastname@example.org and we can review it with you. Cheers, Matt
