In what situation would a respiratory therapist perform suctioning?

Suctioning is an essential procedure performed by respiratory therapists to clear secretions from the airway. This is typically necessary when a patient has an accumulation of mucus or other obstructive materials that can hinder breathing and lead to complications such as infections or reduced oxygenation. By removing these secretions, the therapist aids in maintaining a patent airway, ensuring that the patient can breathe more effectively and comfortably.

While other options might seem relevant, they are distinct from the primary purpose of suctioning. Administering medication directly into the lungs involves a different technique, such as using a nebulizer or inhaler. Collecting samples for laboratory testing, while potentially requiring a similar approach, is a separate procedure aimed at diagnosing conditions rather than clearing the airway. Lastly, assessing airflow in the lungs requires specific diagnostic tests such as spirometry rather than suctioning, which is a therapeutic intervention rather than a purely evaluative one.
