To summarize what we learned:
️Rubbing insulators together accumulates static electricity due to triboelectric charging.

CRRT machines can accumulate static electricity from the roller pump; these charges can discharge into the patient causing an artifact.

Roller pump static electricity can effect EKGs & EEGs (& devices that depend on EKGs like IABPs)

Here’s a fun ICU puzzle: what is causing this crazy spiking pattern on the ECG waveform of both an intra-aortic balloon pump & ICU monitor?

A #MedEd on an important clinical artifact, medical pumps, & the triboelectric effect.

We’ll need to go back 2500 years to understand the cool physics behind this important effect! #FOAMed #FOAMcc #PhysicsInTheICU
