This program was developed to demonstrate the components and processes involved in the transfer of oxygen and carbon dioxide between the lungs and tissues.

Gas exchange is fundamental to life and a detailed working knowledge of O2/CO2 transfer is central to respiratory medicine. The program provides a learning map for students by following the progress of an inhaled oxygen molecule as it crosses the lung alveolar membrane, binds to haemoglobin, transfers to tissues down concentration gradients and finally exists as CO2.

The purpose of the program is to provide a core of knowledge represented by the path of O2. Students are able to use a flexible, interactive teaching program to encourage deeper exploration of the science of gas transfer. Special emphasis is given to developing clinically oriented patient scenarios where the consequences of impaired gas exchange manifest as human disease.
