24 Hour Turn Around Time - The Fastest Turnaround for Medical Equipment

Arterial fibrillation detection

GE Apex Pro Telemetry Features

The ApexPro telemetry receiver is a new space-saving design and can be conveniently mounted to a standard network equipment rack or shelf. Configuration allows up to four quad receiver modules, for a total of 16 multi-channel telemetry receivers in one compact unit. The flexibility to add quads with four receiver channels allows the system to grow with the number of patients which are monitored telemetrically.

The multi-channel receivers are admitted through the Clinical Information Center CIC Pro. The telemetry data is processed there, stored and displayed. The telemetrically acquired ECG-data can also be displayed at a bedside monitor. The use of LAN data transfer technology allows the receiver system to be located virtually anywhere within the hospital. LED displays offer quick, easy assessment of on-line status while diagnostic ports speed troubleshooting.

More Information on the GE Apex Pro

ApexPro provides exceptional detection and analysis of patient data to help you fully and accurately monitor your patients’ status

ApexPro uses the GE EK-Pro* clinical algorithm, which processes and analyzes four independent, simultaneous ECG leads. Plus, an innovative Smart Leads Fail feature helps to reduce false ECG alarms
With GE EK-Pro, ApexPro supports advanced atrial fibrillation detection and alarming
ApexPro has the capability to monitor two V-leads on each patient
Pace detection across two vectors improves the system’s ability to see and recognize a wide variety of pacemakers
Longer operation time than the average length of patient stay (3-4 days). ECG only (110 hours with 2 AA batteries) or ECG and SpO2 (50 hours with 2 AA batteries)
The flexible design of ApexPro allows each transmitter to monitor continuously ECG and SpO2 when needed

Innovative Parameter Technology

GE EK-Pro* four lead arrhythmia analysis provides detection of lethal and advanced atrial fibrillation detection and alarming. Early and accurate identification of AFib may help prevent this arrhythmia from becoming chronic.
Dual V-lead monitoring allows caregivers to be vigilant for both arrhythmias and ST segment changes through a better picture of the patient’s heart.
Dual vector pace detection ensuring an accurate pace detection

Excellent infrastructure technology

Flexible: GE delivers “coverage area” rather than “infrastructure equipment” and can scale to cover up to 28.000 m2
The ApexPro telemetry infrastructure is custom designed for your unique RF environment meeting the specific RF regulatory requirements within your country and facility
Scalable: ApexPro and the CARESCAPE network can accommodate up to 438 CARESCAPE telemetry T4 transmitters in one installation but is limited by the number of RF frequencies available for medical telemetry usage in a specific country and hospital.
ApexPro operates within the Frequency Range: 420.025 to 459.975 MHz.
Dependable: Quad-diversity antenna infrastructure searches four separate antenna fields each second for the best signal from each patient
