Calculate Total Heparin Rate
Learn how to use the infusion history screen to account for heparin in the purge fluid when calculating total heparin rate to avoid supratherapeutic dosing.
Weaning and Escalation
Tim Larkin, MD, describes his weaning protocol for Impella RP during this physician Q&A session.
Handling Impella RP® Suction Alarms
Suction is most often caused by inadequate preload or malposition.
As with all other Impella® heart pumps, if a suction alarm occurs:
- Decrease P-level to break suction.
- Evaluate patient volume status. Maintain a positive CVP.
- Check Impella RP position and adjust as needed using chest X-ray, fluoroscopy, or echocardiography.
- When suction is resolved, return to previous P-level.
If position and preload are acceptable and suction cannot be resolved at P-2 or P-3, momentarily stop the Impella RP to break the suction event and restart immediately.
Note that this is different from handling suction alarms with other left-sided Impella heart pumps.
Systemic IV Heparin Rate Calculator
Calculate total heparin delivered to the patient, which includes heparin from both the Impella heart pump’s purge system as well as the systemic IV heparin.
