Simple spirometry measurements
WebbWhile simple spirometry is an invaluable test for assessing respiratory function, it does not always give sufficient information to diagnose respiratory disease. Using spirometry alone it is not possible to measure the maximum capacity of the lungs, as spirometry can-not measure the residual volume (RV) of gas remain- Webb6 feb. 2024 · To measure the volume, a simple spirometer was constructed using a cylindrical container, some sections of solid PVC pipe and the graduated base of a soft-drink bottle as shown in Figure 5. The overall accuracy of the device will be affected somewhat by changes in temperature and the resulting condensation in the Fleisch cell.

WebbWhat does simple spirometry measure? It is a simple, non-invasive breathing test that measures the amount of air a person can blow out of the lungs (volume) and how fast he or she can blow it out (flow). Based on this test, your doctor or health care provider can tell if you have COPD, and if so, how severe it is.
