MDPro professional-grade ECG trunk cables are designed to provide stable, low-noise cardiac monitoring for the Guardian Plus system. The defibrillation-proof models (009-005266-00 and 009-005267-00) feature integrated circuitry that protects the patient and the monitor's internal components during emergency defibrillation pulses, allowing for continuous connection. The ESU-proof versions (009-005268-00 and 009-005269-00) are specifically engineered for the operating room, utilizing advanced filtering to suppress high-frequency electrical interference from electrosurgical units (ESU). Both series are available in 10-foot and 20-foot lengths, featuring durable TPU jackets and secure, round 12-pin keyed connectors to ensure reliable data transmission in high-acuity clinical settings.
