3. WHAT IS THE VITALOGRAPH COPD-6 BT USED FOR?

The Vitalograph copd-6 BT is a device intended for measuring lung function. It can be used by a healthcare professional or assistant as a rapid pre-spirometry test to screen-out at-risk individuals that do not have COPD and indicate those that may be at risk of COPD at the pre-symptomatic stage of the disease. This “screening” or “case selection” for full spirometry examinations may result in earlier medical intervention and facilitate better clinical outcomes.

The Vitalograph copd-6 BT displays some key parameters for clinical interpretation:

If an abnormal result is indicated, arrows on the display show:

 

4. HOW TO USE THE VITALOGRAPH COPD-6 BT

4.1 Entering Subject Data

The subject’s physical data can be entered into the Vitalograph copd-6 BT in order to calculate predicted data.

To enter the subject data, follow these steps:

  1. Turn the device on, On.
  2. The age can now be set ( Age). This is done by pressing the Up or Down button and releasing when the age is reached. The values will increase/decrease in values of 1. If the button is kept depressed, the values will scroll faster. Press the Enter button to set the age.
  3. The height can now be set ( Height). This is done by pressing the Up or Down button and releasing when the height is reached. The values will increase/decrease in values of 1. If the button is kept depressed, the values will scroll faster. Press the Enter button to set the height.
    Note: if height values are set below 100, the device assumes height is in inches and that Weight will be in Ibs rather than Kg.
  4. The gender can now be set ( Gender). This is done by pressing the Up or Down button and releasing when the correct gender is showing. (Male ( Male); Female (Female )) Press the Enter button to set the gender. After gender is selected, the Vitalograph copd-6 BT will go to Test Mode, where the Blow Icon is showing. On some variants, an additional data field comes first (see below).
  5. (This step may be omitted, depending on the variant) The Population Group (on some variants this is Weight instead) can now be set ( Population). This is done by pressing the Up or Down button and releasing when the desired setting is reached. Press the Enter button to set.

 

Set No. Example Population Group
1 NHANES III Caucasian C
2 NHANES III African-American AA
3 NHANES III Hispanic-American HA

 

4.2 Performing the Test

  1. The subject should sit down when blowing into the device (unless advised otherwise). Insert a new disposable SafeTway mouthpiece into the device.
  2. Turn the device on, On (if not already ON). When the device is ready for a test the blow icon shows ( Blow).
  3. Instruct the subject and demonstrate (using a mouthpiece) as follows:
    1. “Hold your head up, breathe in as deeply as possible, hold the device in front of your mouth”.
    2. “Hold your breath, place the mouthpiece into your mouth, like this, bite the mouthpiece lightly, and seal your lips firmly around it, like this”. I will demonstrate.
    3. “Blow out as HARD, and FAST as you can, like this, until I tell you to stop” (the unit will beep at end of test - after 6 seconds).
    4. “Be careful not to block the mouthpiece with your tongue or teeth. A ‘spitting’ action will give false readings”.
    5. “Now you do it – deep breath in – bite and seal – blast the air out…keep going – keep blowing”
    6. “Well done!” “Now, we need to do that three times. Rest for a while until you are ready to blow again”.
  4. To view the result (the best values in the session), press the Enter button.
    1. The COPD Classification will show on the right hand arrow.
      1. Green is NORMAL, negative for COPD. No need to refer this subject for spirometry.
      2. Any one of the blue zones, I, II, II or IV are not normal. This subject should be referred for spirometry.
    2. The Obstructive Index (OI) shows on the left hand arrow.
      1. 0 - Green is normal.
      2. 1, 2 or 3 – Yellow, amber or red are not normal. Refer for spirometry, but this is unlikely to be COPD.
      3. Note: If the right hand (COPD) arrow is not green, nor will the left hand (OI) arrow be green.
  5. This is the end of the test, but if desired some test parameters may be viewed.
  6. Following each blow and at the end of the test session, the FEV1 value will be displayed and below that, FEV1 % Predicted results for that blow, or for the best in session if the Enter button has been pressed. Pressing Enter again will toggle between best and last blow.
  7. Pressing the Up button will show the FEV6 and FEV6 % Predicted results.
  8. Pressing the Up button again will show the FEV1/FEV6 and FEV1/FEV6 % Predicted results
  9. Press the Up button for a final time will show the estimated Lung Age ( Lung)

Notes on testing:

  1. During testing, if an exclamation mark ! appears, this means that the last blow was not a good quality blow and the user should blow again. Reasons for poor quality are;
    1. Slow Start of test: Vext (extrapolated volume) is > 5% or 150mL of FEV6
    2. Cough detected.
  2. In the event that a test is < 3 seconds duration and has an abrupt end (change in volume is > 25ml in the last second of the test), the value FEV will be displayed instead of FEV6.
  3. If the test subject experiences side effects such as dizziness or fatigue during the test procedure, stop testing until recovered.

 

5. SENDING TEST RESULTS TO VITALOGRAPH REPORTS

The test session may be transmitted to the Vitalograph Reports Utility on your PC where it can be stored as a PDF file and viewed or printed.

This device is not designated as a ‘sterile’ device.

 

6.5 Removing the Flowhead for Cleaning and Disinfecting

Disassenbled Assembled
Flowhead Disassembled Flowhead Assembled
  1. Remove the flowhead from the body with a sharp pulling motion.
  2. Clean the flowhead by washing in a mild detergent to remove particulate contamination, taking care not to touch the moving vanes. Swill vigorously in water with mild detergent. Do not attempt to “rub” or “scrub” in the area of the vanes. Rinse with clean water.
  3. Disinfect by immersion in sodium dichloroisocyanurate solution at 1000 ppm concentration of free chlorine for 15 minutes. Prepare disinfectant solution as directed in the manufacturer’s guidelines. Rinse with warm water for faster drying.
  4. Leave it to dry completely before reassembling. Drying the flowhead may require placing it in a warm place overnight. A drying cabinet is ideal.

Wiping with a 70% Isopropyl Alcohol impregnated cloth provides a suitable form of cleaning and low-level disinfection for the case exterior, display, screen surround and keys. Repeat this at least weekly to prevent a build-up of grime from normal handling and use. Always follow the safety guidelines given by the manufacturer of cleaning and disinfectant chemicals or equipment.

Reassemble the flowhead by pushing back on until it ‘clicks’ into position. Ensure that the flowhead is pushed fully home.

Definitions of cleaning and disinfection are as defined in “Sterilization, Disinfection and Cleaning of Medical Equipment: Guidance on Decontamination from the Microbiology Committee to Department of Health Medical Devices Directorate, 1996”

Recommendations for chemical disinfectants are derived from the PHLS publication “Chemical Disinfection in Hospitals 1993"
