Abstract

Progress in computer simulation technology offers new possibilities for modern medicine. On one hand – virtual organs can help to create animal or human models for research, on the other hand – e-learning or distant learning through Internet is now possible. The aim of our work was to create a system for interactive learning of spirometry (SILS), enabling students or physicians to observe spirometric measurements (flow-volume) modified by setting level and kind of abnormalities within the respiratory system.
SILS is based on a virtual respiratory system presented previously in several papers. Its main features are: separation of the lungs and chest; anatomical division of the lungs; division of airway resistance into transmural pressure dependent (Rp) and lung volume dependent (Rv) parts. The one mathematical formula that represents Rp describes both flow limitation (forced expiration) and dependence of Raw on lungs volume (small airflows). The output of system are spirometric parameters (as FEV1, FVC, FEV1%FVC) and a flow–volume loop constructed according to results of simulation of forced expiration for the chosen abnormality kind and level.
As a result – this system may be used in teaching process in medical schools and postgraduate education. We offer access to a basic version of SILS for students and physicians at: www.spirometry.ibib.waw.pl and www.zpigichp.edu.pl . As we expect feedback from users, it is possible to modify user interface or model features to comply with users‘ requests.
