GE Apex Pro

Features of GE Apex Pro Telemetry:
The ApexPro telemetry receiver features a compact design suitable for mounting to a standard network equipment rack or shelf. Its configuration allows for up to four quad receiver modules, accommodating a total of 16 multi-channel telemetry receivers within a single unit. This flexibility enables the system to expand in tandem with the number of patients undergoing telemetry monitoring.

Multi-channel receivers interface with the Clinical Information Center CIC Pro. Telemetry data undergoes processing, storage, and display at this central location. The ECG data acquired telemetrically can also be viewed on a bedside monitor. Utilizing LAN data transfer technology allows for the receiver system's versatile placement within the hospital. LED displays facilitate quick online status assessment, while diagnostic ports expedite troubleshooting.
