Lung capacities calculation.
| Download Spirometry desktop application (Windows 64bit) | Download Spirometry source code (Lazarus/Free Pascal) |
Description: Calculation of the lung volumes and capacities, based on the values as read from a spirogram. As spirometry does not
allow to measure the residual volume, it can't be neither directly entered with this application. Two possibilities are offered to the user: 1. Calculate it
from FRC (measured by helium dilution technique or nitrogen washout method, resp. entered directly). 2. Estimate it by using the approximation: RV = 0.24 * VC
(men), resp. 0.28 * VC (women). Please note that all volumes must have the same unit (normally ml); concentrations for FRC calculation are supposed to be given
as percentages.
Free Pascal features: Basic controls: radio groups, radio buttons, input fields, push buttons. Enabling/disabling tab stops depending
on actual situation.
