What is a suitable setting to encourage a child to achieve their full inspiratory capacity with an incentive spirometer?

To encourage a child to achieve their full inspiratory capacity with an incentive spirometer, it is important to select a volume that is both achievable and encouraging. The lower volume of 700 mL is suitable for children, particularly those who may be younger or have smaller lung capacities. This capacity allows for the child to comfortably take deep breaths without becoming overwhelmed or discouraged.

As children are still developing their respiratory muscles and lung capacities, a volume that is too high can lead to fatigue or frustration, potentially discouraging them from using the device effectively. Therefore, starting with a 700 mL setting provides an accessible goal that can promote successful participation and engagement in the incentive spirometry process, allowing them to gradually build their confidence and capacity.

Higher volumes, such as 1000 mL or above, may not be appropriate for all children, particularly those who are not accustomed to deep inhalation or have underlying respiratory issues that limit their lung function. These options may lead to attempts that exceed the child's capability, which could hinder rather than promote their progress.
