BASELINE 12-1710 Windmill-Type Spirometer fig \(2\)

Windmill-Type Spirometer

  • lightweight, easy-to-grasp spirometer measures forced vital capacity
  • broad measurement range from 1000cc to 7000cc with 100cc gradations
  •  can be used as an incentive spirometer, exerciser or screening device
  • comes in case with a spirometer and 50 disposable mouthpieces
  • additional mouthpieces available

Specifications

  • ● measurement range 1000cc to 7000cc with 100cc graduations

How to use

  • slide the small end of the mouthpiece (d) onto the spirometer nozzle (c)
  • confirm white indicator pointer is set to zero; if not at zero, adjust by rotating outer ring (a) to right or left until the indicator points to zero

Holding the spirometer during use

  • hold spirometer horizontal during use, with the dial facing up and the nozzle towards mouth
  • keep the spirometer steady during the measurement
  • when in use do not cover small holes (b) on the side of the upper body conducting the test
  • inhale deeply stretching body upward; do not place the mouthpiece between lips while inhaling
  • after maximum inhalation, place the mouthpiece between lips; breath out strongly in one motion, making sure all air is forced into the mouthpiece; breathe out for 5-6 seconds; use a similar technique

During each trial

  • read the measurement on the spirometer dial after breathing out; record the value and reset the dial to zero by rotating outer ring to the left or right
  • repeat the test 3 time; the maximum value indicates FVC
  • discard used mouthpieces after an individual is tested

Caring for your spirometer

  • to clean spirometer remove lower body (e) by turning it clockwise; after 9 measurements clean the inside lower cavity of the spirometer with a cot-ton swab dipped in an alcohol/disinfectant solution and dry; (if mois-ture or dust is present in cavity accuracy can be lost)
  • this spirometer is a precision instrument so handle with care

Tables of FVC measurement norms

  • spirometry prediction tables for normal healthy males and females are available to the public to view from the United States Department of Labor in Standard Number 1910.1043 App C; Title “Spirometry prediction tables for normal males and females”

  • tables include the predicted value of FVC; sorted by Sex, Age and Height

  • viewable to the public at the OSHA website www.osha.gov
    input 1910.1043 App C in the search box according to the tables referenced above:

    • predicted FVC for a male is greater than female of similar age/height
    • predicted FVC increases as height increases for same age/sex
    • predicted FVC value peaks for males around age 23-25
    • predicted FVC value peaks for females around age 21

Predicted normal values FVC
