What does a sawtooth pattern indicate in a time flow diagram?

A sawtooth pattern in a time flow diagram typically indicates the presence of airway secretions. This pattern represents irregular airflow, often caused by obstruction due to mucus or other secretions in the airways. As air passes through these obstructions, the flow becomes sporadic, creating the characteristic sawtooth appearance in the graphical representation.

In clinical practice, recognizing this pattern is crucial for identifying issues with airway patency. It prompts healthcare providers to assess the patient for potential airway clearance needs, such as suctioning or other interventions to improve ventilation and respiratory function.
