IABP augmented pressure

  1. 0
    Can you tell me please that when a patient is on IABP, We always mention augmented and diastolic pressure even though both systolic and diastolic reading displayed on IABP machine.

    the above link gives great rationale for the different pressures we look at on iabp pts and why each is important. Remember, the goal with these pts is to decrease the hearts work and to increase oxygen supply. The balloon pump inflates during diastole, which is when the coronary arteries are filling. When the pump inflates, it forces blood flow backwards to the coronary arteries so they get more oxygen.

    also remember that the artline going to most regular central monitors doesn't measure the difference between 3 numbers: aug dia/sys/dia. IF you record vitals from the central monitor, you aren't recording actual values, but the computer's interpretation of 3 values into 2.

    Your balloon pump measures those distinctions.

    We use sys97e from datascope.

    The problem w/ recording is this: our balloon pump isn't linked to the central monitor (although I know this is possible for some) or a continual recorder (although it will record on demand). So, to get the values correct, I have to either estimate from the trend line that the IABP will print on demand, look and write in real time, or this:

    You can have the machine print EKG, ABP, Trend, Balloon Waveform at any time. When you tell it to stop, it will finish by printing a current readout of: hr/aug dia/sys/dia/map/mode/ etc.

    So, if I'm taking vitals say, every 15-30 min, I'll go to the machine and start it printing one of its waveforms, and then immediately stop it. It's not the waveform I want, but the current readout printed up at the end. I can then go back later and pull that printout and add it to my charting - at my leasure with real time data faithfully recorded.

    I hope that makes sense.

    I always mention and document all three IABP BP values. But for practical purpose, the 'augmented diastolic' is the top pressure (assuming good 'augmentation'.) followed by systolic then diastolic (unaugmented).

    My question: Are you always mentioning just 'augmented diastolic' and diastolic, or are you hearing 'augmented diastolic' and separating the terms.

    The pump inflates on diastole and creates an artificially higher diastolic pressure during diastole, as a result. So, that diastolic pressure, now the highest pressure (again, assuming the desired affect from the machine), isn't just a diastolic pressure now, but an 'augmented diastolic' pressure. The machine has augmented the pressure during diastole.
