IABP calibration

[Sufenta]

Had a pt with IABP Maquet datascope cs300 this week. Brochure says it...auto calibrates the fiberoptic pressure sensor in the patient & recals Q2h or sooner should the pt or environment change.

So...is it calibrating to an atmospheric level? Is moving the bed with the IABP stationary a problem? What kind of changes cause earlier recal?

I didnt trust it, so placed & transduced a radial a -line. Checked that zero several times. Was surprised to see during case that my radial read 20 pts higher than the augmented pressure on IABP. But, the case was more than 2 hrs and the relationship never changed.

Insight, please?

was the difference in the means or in the systolic pressure?

It's normal for radial systolic to measure higher than aortic systolic pressure, but the MAPs should be about the same.
