What is a symptom that might necessitate the use of a cough assist device?

Cough assist devices are specifically designed to aid individuals who have difficulty clearing secretions from their airways due to conditions that impair their ability to cough effectively. Excess mucus in the lungs presents a significant challenge, as it can obstruct the airways and lead to further respiratory complications such as infections or difficulty breathing.

When an individual has a buildup of mucus, their normal cough reflex may not provide sufficient force to expel it. In this case, a cough assist device can help by providing a mechanical means to generate increased expiratory airflow, mimicking the natural cough process and thereby facilitating the clearance of mucus. This is essential for maintaining clear airways and promoting lung health, particularly in patients with neuromuscular disorders or other conditions affecting respiratory function.

In contrast, symptoms like increased energy levels, clear breathing sounds, or improved oxygen saturation do not indicate a need for a cough assist device, as these suggest that respiratory function is currently adequate.
