Complete PC based office diagnostic system.

The Universal ECG features accurate results, real-time graphical display and narrative interpretation. The Universal ECG saves you money by eliminating thermal paper and calibration and minimizing required maintenance.

The Orbit portable spirometer features improved accuracy, portability and USB 2.0 connectivity. This next generation QRS Spirometer easily connects with your PC and rests on the table top.

Features and Benefits

ECG Features

  • Incomparable Accuracy - The Universal ECG uses the Louvaine analysis program. The Louvaine algorithm had the best total accuracy of the 9 popular algorithms compared by cardiologists to a standardized database of ECG tracings.
  • Multiple Report Options - Office Medic offers multiple options for viewing the Universal ECG reports and they are transferable to PDF, JPEG, or TIFF formats.
    • 3x4 Simultaneous
    • 3x4 Sequential
    • 6x2 ECG
    • 6x1 ECG
    • Averaged Complexes
    • Measurements Report
    • Avg. Zoom Report
    • Zoom Report
  • Lightweight & Portable - The Universal ECG weighs less than 12 ounces and can easily be transported to new patient rooms, clinic locations or any off site location where an ECG needs to be performed. Also, no batteries are required for the Universal ECG because it draws its power from the computer (connected via USB port).
  • Why Perform Diagnostic ECG Tests? - ECG testing has increased the diagnosis of heart disease. ECG's provide physicians a baseline to compare the health of a heart on a recurring basis. They also help diagnose, monitor and treat patients with symptoms of heart health issues.

Spirometry Features

  • Standards - The Orbit provides effective diagnostic tests and meets the following Standards:
    • American Thoracic Society (ATS/ERS) 2005 Standard
    • British Thoracic Society (BTS) Standard
    • National Institute for Health & Clinical Excellence (NICE) Guidelines
  • Lung Age Calculation - Lung age is calculated for patients ages 20-84. It is equal to the predicted FEV1 that matches the patient’s actual FEV1. Lung age may differ based on the predicted equation chosen.
  • Patented, Pre-Calibrated Mouthpiece - With the Orbit spirometer system, everything the patient touches is thrown away. No sterilization or calibration is necessary, saving time for nurses, therapists and physicians.
  • No Batteries Required - The Orbit draws its power from the PC it is connected to by USB port.
  • Calibration not required.
