Activity 3 - Obstructive lung diseases
In this activity, the spirometer recording trace has been shown simulating the lung function tests on a patient who as an obstructive disease such as asthma.
- Press Start to begin quiet breathing.
- After a few moments, press Perform VCM to simulate a vital capacity manoeuvre.
Note: The simulation runs at × normal speed
Use the spirometer trace to estimate the subjects’; forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1).
The percentage of air exhaled in the first second (FEV1/FVC%) will be automatically calculated from your answers.
