BASELINE 12-1710 Windmill-Type Spirometer
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
