A change in the PA waveform and pressure are noted. A dicrotic notch is no longer visible. Values change from 36/15 to 30/3. What action should the nurse anticipate? ?Removing the syringe from the balloon port. A sudden drop in the waveform's values, accompanied by a loss of the dicrotic notch, could indicate catheter slippage from PA to RV. Inflating the balloon may help the catheter float forward into the PA. Notify the provider for possible catheter repositioning. A patient with s...
