Artifact Elimination Strategy Rules/Logic
Provider marked artifacts Marked as artifact in real time by the provider
Artifact from arterial line SBP > 200 and PP < 50
clamping, damping, or flushing; or cuff under external pressure SBP > 150 and SBP ≤200 and PP < 30
SBP ≥ 100 and SBP ≤ 150 and PP < 15
SBP < 100 and PP < 10
Artifact from arterial line or cuff transducing signal but disconnected from patient SBP ≤ 10 or DBP ≤ 10
SBP = DBP = MAP
MAP < 0
MAP ≥ 140
If any BP is marked as artifact, then all BP
measurements for that time will be marked
as artifact

If artifact other than provider-marked, is detected for SBP, DBP, or MAP for a specific reading, then all three blood pressure values are marked as an artifact. BP, blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; PP, pulse pressure (SBP – DBP); SBP, systolic blood pressure.
