A-line readings "filter?"

  1. Can anyine explain how the filter works on the a-line. Our monitors allow you to adjust the filter from 3 to 40. What do these different values mean?

    No clue here. You may want to look in the manual for that specific monitoring system for a description.

    On our monitors, we have a filter for the ECG. It filters out artifact.

    Not sure about art lines.

    Interesting question.

    Might have to do with artifacts in the waveform r/t pt movement (shaking the transducer cable?) Not sure. Just hazarding a guess.

    (Which brings up an old trick: When you are confronted with a patient who has a lot of lines, pick a transducer and shake it. nhe waveform that goes crazy is the line in question. Given how badly the OR can entangle people [disentangled a central line from a foley from a peripheral IV the other day but that's another story entirely ] it actually comes in handy!)
