What is the primary assessment responsibility of a respiratory therapist when evaluating a patient with respiratory complaints?

The primary assessment responsibility of a respiratory therapist when evaluating a patient with respiratory complaints is to obtain a history of present illness. This step is crucial because it provides a comprehensive understanding of the patient's condition, symptoms, onset, duration, and any exacerbating or relieving factors. Gathering this information establishes a foundation for further evaluation and aids in forming a differential diagnosis.

While measuring oxygen saturation levels, performing arterial blood gas analysis, and conducting diagnostic chest percussion are all important tasks that a respiratory therapist can carry out, they typically follow after obtaining the initial history. Each of these procedures informs management decisions but relies on the context provided by the patient's history. By understanding the patient’s specific complaints and background, the therapist can prioritize assessments, choose relevant diagnostic tests, and tailor interventions that address the underlying issue.
