Spirometric normal values

spirodoc is a precise measurement instrument which measures the main spirometric parmeters during a test of "forced
expiration". At the end of each test the machine gives also a suggested automatic interpretation for the respiratory
function of that subject.
In order to make a correct evaluation of a spirometry test the measured values must be compared with the " normal (or
predicted) values" . These values are taken from a healthy population and are calculated from tables or formulas in
function of the age, height and sex of the subject in question.
spirodoc automatically calculates the relevant " normal values " and compares them as a percentage with the "measured
values".
An example of such a calculation is shown below:
parameter FVC: % = FVC measured / FVC normal x 100
2. OPERATION OF THE SPIRODOC
2.1 Keyboard
All spirodocs have a keyboard
consisting of 5 keys:
"↵ ↵ ↵ ↵ "
The key ( ) has several
functions:
SWITCH ON to switch on the spirodoc press and release
SWITCH OFF to switch off the spirodoc press the key for at least 2 seconds
ENTER to confirm and to proceed to the next phase
The " ∇ ∇ ∇ ∇ " is generally used:
• to answer the questions shown on the display
• to reduce/modify a value highlighted with an arrow
The " " key is generally used:
• to answer the questions shown on the display
• used to change the anthropometric data of the patient or to correct recently-input data
The " ∆ ∆ ∆ ∆ " key is generally used:
• to answer the questions shown on the display
• to increase/modify the value highlighted with an arrow
