What Is the Physio-Control 11111-000018 Compatible 4-Lead One-Piece ECG Cable?

The IPR Medical EC-4039RS-A is a compatible aftermarket (not OEM) 4-lead one-piece ECG cable that replaces the Physio-Control 11111-000018. It brings four snap-ended limb leads and the main cable together in one reusable assembly with AHA color coding. A defib-proof feature is listed, and the cable is intended for ECG monitoring.

Compatible Monitor Models

Select Physio-Control models appear on the compatibility list for the EC-4039RS-A, with entries for the Lifepak 11, 12, 15, 20, and 20E. Your monitor’s model should appear in the compatibility table on the Specifications tab before you place the order.

Design and Construction

All four leads are for limb placement and end in snaps, colored to the AHA code as RA white, LA black, LL red, and RL green. With a specified length of 8.2 ft + 3.0 ft (2.5 m + 0.9 m), the cable is listed as defib-proof for monitoring use. Each cable comes in its own bag and is meant for reuse once it has been cleaned between patients as facility protocol requires.

When to Replace Your 4-Lead One-Piece ECG Cable

Replace the cable when a limb lead shows intermittent signal loss, when lead-off warnings continue after the electrodes are changed, or when artifact appears every time the cable moves. Visible damage matters too: a snap that has lost its grip, a split or flattened jacket, or a monitor connector with bent pins or a cracked housing. Biomedical staff can isolate the problem by connecting a known-good cable to the same monitor and comparing the traces.

Cross Reference and Interchange Part Numbers

Physio-Control 11111-000018 is the OEM part number this cable cross-references. No aftermarket interchange numbers are listed for it, so that single OEM number is the whole cross-reference table on the Specifications tab.
