GOLD conforming staging classification-display possible.

This complies with the guidelines concerning the Japanese Society of Ningen Dock health check result judgment and follow-up guidance.

Adopts the pneumoconiosis health diagnosis judgment criteria

Adopts the Japanese child spirogram reference value(http://jspp1969.umin.jp/ind_img/spirogram.pdf

Uses large-scale LCD

With an easy-to-understand large color display on the LCD, recognition is greatly improved. (307 is black and white)

Uses an easy-to-operate touch panel

Operability is greatly improved through the adoption of a touch panel. This can be simply operated by merely touching the icon display button with your fingertips.

Uses a judgment bar on the measurement results screen

Displays a general judgment bar and FVC bar on the measurement results screen. In the general judgment bar, the classification of staging and ventilatory function impairment based on GOLD is possible. The FVCjudgment bar displays the judgment results such as effort levelfrom ATS.

Reliability of data and screening results can be confirmed at a glance. By touching the general judgment bar or FVC judgment bar, this detailed screen can be displayed.

From the FVC judgment bar detailed screen, the level of effort and possibility of reproducibility at the time of FVC measurement based on the ATS standard, and on the general judgment bar detailed screen, the staging classification results, ventilatory classification and BD judgment based on GOLD are displayed.

Do you know about lung lifestyle-related diseases....?

In recent years, COPD (*1) has been gaining attention as a lung lifestyle-related disease.

The main cause of COPD is habitual smoking and it is sometimes referred to under the different name of “smoking disease”. There are said to be 5.3 million potential patients in Japan and it ranks 4th in the world in terms of cause of death.

Whereas heart disease and cerebrovascular disease are on a downward trend, only COPD is on the increase, so GOLD (*2) are creating international guidelines and promoting countermeasures. Among these, examination methods using a Spirometer and disease phase classifications have been stipulated.

  • ※1 COPD: Chronic Obstructive Pulmonary Disease.
  • ※2 GOLD: Global Initiative for Chronic Obstructive Lung Disease

Early detection using a Spiro examination is important

As COPD is a progressive illness, it is said that detecting it early and preventing the progression of the lesion is important. Further, the Spiro examination is the most effective method of examination for discovering it at an early stage.

Middle-aged and elderly smokers and those with symptoms of breathlessness, coughing and phlegm should first undergo a Spiro examination

COPD is known as smoking disease and it is recommended in particular that middle-aged and elderly smokers or those with a history of smoking should have Spiro examinations on a regular basis.

Spiro examinations are important in the management of asthmatic patients

Spiro examinations are also useful for selecting asthma treatment methods and judgment.

COPD staging classification based on GOLD

The GOLD staging classification is judged using forced vital capacity, forced expiratory volume in 1 second in the FVC examination as well as the predicted value.

FEV1.0/FVC(%) 1 second forced expiratory volume rate (forced expiratory volume in 1 second/forced vital capacity)
%FEV1.0(%) % forced expiratory volume in 1 second (forced expiratory volume in 1 second/predicted forced expiratory volume in 1 second)

The staging classification is judged from the 2 measurement values and summarized in the easy-to-understand way shown in the table below.

COPD staging classification (2003 edition)

0: At Risk FEV1.0/FVC ≧ 70% Spirometry is for normal chronic symptoms(cough, phlegm)
I:Mild COPD FEV1.0/FVC < 70% FEV1.0 ≧ 80% predicted regardless of whether there are chronic symptoms(cough, phlegm)
II:Moderate COPD FEV1.0/FVC < 70% 50% ≦ FEV1.0 < 80% regardless of whether there are chronic symptoms(cough, phlegm)
III:Severe COPD FEV1.0/FVC < 70% 30% ≦ FEV1.0 < 50% predicted regardless of whether there are chronic symptoms(cough, phlegm)
IV:Very Severe COPD FEV1.0/FVC < 70% FEV1.0 < 30% predicted or FEV 1.0 < 50% predicted with chronic respiratory failure

Function

Function

Through the large, easy-to-view display and touch keys that can be switched for each input item, it is easy to input the ID items.

MVV measurement screen (AS-507 only)

MVV measurement screen (AS-507 only)

The tidal volume and integrated quantity are displayed simultaneously.

Even if the measurement is stopped midway, the data up until the stipulated time is extrapolated and calculated.

VC measurement screen

VC measurement screen

Directions are displayed in a timely fashion during the measurement. The measurement can be automatically completed.

Using the latest VC measurement algorithm, more accurate measurement is possible.

FVC measurement screen

FVC measurement screen

The call time and the flow using flow display bar are displayed.

Where the flow decreases, the display will automatically expand and can be called until the end.

In addition, it is possible to check the effort level specified by ATS and obtain highly reliable data.

ATS compliant new design transducer

  1. *For group examinations etc.,
    an economical paper mouthpiece is provided.
  • Transducer that is compact, light, easy to operate and easy to carry. High accuracy (shipment standard:
  • indicated value ± 3%) hot wire type.
  • Clean air filter with built in electrical air filter for preventing infection.
  • Made of high quality resin to fit gently in base of mouth and enable patients to be examined without discomfort.

Accuracy management

Accuracy management is important in order to leave correct measurement results. Includes accuracy management functions based on Japanese Respiratory Society guidelines.
