Pulmonary exercise load monitoring system High accuracy measurement value management has been realized with the development and adoption of the latest technology of “Universal design” universal design, “gas transport time automatic compensation mechanism”, from medical field to sports medicine field.

What is “gas transport time automatic compensation mechanism”?. . .

Since VO 2 (oxygen uptake) and VCO 2 (carbon dioxide emissions) are obtained by multiplying and integrating changes in flow (flow rate) and gas concentration in real time, the time axis of three factors of flow, O 2 concentration, and CO 2 concentration Must be the same. Here, since the response speed of the sensor that measures each of these three factors is different, it is necessary to compensate these time axes on the same time axis. The normal flow is a real time signal, and the O2 / CO2 concentration measurement is introduced to the sensor via the sample tube, so a delay occurs in the signal. Generally, as a method to compensate for this, the compensation value is calculated at the time of calibration before the inspection, and the flow signal is delayed according to the gas concentration signal and processed. These treatments compensate based on resting, so even if the state of breathing changes during exercise, it is fixed value and processed. In order to solve this problem, Cpex-1 adopts a “gas transportation time compensation mechanism” and constantly monitors fluctuations in flow and gas concentration at every breath (breath-by-breath) during measurement, Automatic correction was made so that the cross point (the point where flow direction changes from exhalation to inspiration) and O2 concentration and expiratory end point of CO2 concentration are in agreement, making highly reliable measurement possible.

Measurement screen

  • Even during measurement, “measurement item” and its “range” can be changed arbitrarily at any time as desired.
  • Test measurement (pre-measurement) can be performed before measurement starts, and recalibration can be carried out immediately if necessary according to the result, so that actual measurement can be started with reliable accuracy.
  • On the sub screen, you can monitor changes over time of V – Slope, TV – RR, VE – VCO 2 in real time, and reference information such as progress of AT point can be visually confirmed during measurement.
  • The O2 concentration, CO2 concentration, and flow value can be monitored in real time as a sub screen analog monitor. (option)

Measurement screen

  • Medical field Diagnosis of heart disease / respiratory disease / classification of severity / judgment of treatment effect / cardiac rehabilitation / respiratory rehabilitation / exercise prescription such as lifestyle diseases / static fields such as ICU · CCU
  • Evaluation of cardiopulmonary function from General Health Promotion / General Healthy Person to Athlete / Determination of General Training Strength
  • Nutrition field Basic metabolic measurement / energy metabolism measurement

Analysis screen

  • The AT value can be automatically determined with three types of V-slope method, VE-VCO 2 method, VE-VO 2 method with the AT value automatic decision support algorithm installed.
  • The determination of the time constant can be determined more accurately than the actual measurement.
  • The RC value can be determined automatically.
  • Various analytical values determined automatically can be corrected and determined manually based on the know-how of the examiner.
