According to the solutions, it states: The ERV button simulates a forced expiration.


1. Residual volume is the air remaining in the airways and the lungs which prevents the alveoli from collapsing.

2. The helium dilution method is used to calculate the residual volume.

3. Prior to a cough, the respiratory rate will be regular on the spirogram. During a cough, the respiratory rate
becomes irregular and there are more pronounced expiratory events.
