Oxycon mobile device

Wireless, portable cardiopulmonary stress testing system

Oxycon Mobile from CareFusion lets you determine metabolic response while exercising, working or in settings that traditional, stationary metabolic systems cannot. The device records breath-by-breath data mounted to the subject's body via a comfortable vest and allows testing in children to adults and patients to athletes. 

  • Data is collected through a facemask or mouthpiece and is sent to a host computer system via wireless transmission (telemetry), making the device suitable for use in a non-laboratory environment. View More...
  • Oxycon Mobile's software includes Spirometry, exercise Flow Volume Loops, online registration program for the transmitted data, evaluation software and reporting system.
  • The optional 12-channel ECG is transmitted wirelessly to optimize control.
  • Volume measurements with a very lightweight, precise, bi-directional digital volume transducer (DVT), which can be placed directly at the mouth that is insensitive to water vapour and breathing gases; dead space 30 mL.
  • Sensorbox (SBx): Housing the fast response electrochemical oxygen measuring cell (response 80 ms after digital filtering) and a very fast hot wire carbon dioxide analyser (response less then 80 ms).
  • Data exchange unit (DEx): Unit that collects data from the Sensorbox (ventilation, O2, CO2, SpO2 3 lead ecg and heart rate via polar belt) and sends it telemetrically (range 1,000 m in open space area) to a base station connected to a computer.
  • Software includes automated calculations such as Anaerobic Threshold types (AE, AT, RCP), parameter display shows color-coded upper and lower limits of normal, sub-program macros for user-definable controls such as automated blood pressure recording and more.
  • Optional wireless 12-lead ECG and further external battery pack for long term measurement.
