The arterial line for the REBOA is narrow and can thrombose easily. Frequent flushing of the arterial line by medical personnel is often necessary every 15 minutes if remaining in place. Careful and diligent monitoring of the arterial waveform is necessary: if it appears the arterial waveform has dampened, flushing of the arterial line may be necessary. Often, it may be helpful once the patient is better resuscitated to place a radial arterial line to continue to monitor proximal blood pressure in the event that the REBOA arterial line thromboses, malfunctions, and/or can no longer transduce (as this may occur in a low flow state).
