What is a common indication for using a Swan-Ganz catheter?

• A. Role in fluid resuscitation
• B. Assessment of long-term heart rhythm
• C. Management of peripheral vascular disease
• D. Evaluation of right heart function in critical illnesses

Answer: (D)

The Swan-Ganz catheter, also known as a pulmonary artery catheter, is primarily utilized for the evaluation of right heart function, especially in critically ill patients. This catheter allows for the direct measurement of pulmonary artery pressures, which provides valuable insight into the hemodynamics of the heart. It is particularly useful in diagnosing and managing conditions such as congestive heart failure, shock, and pulmonary hypertension. By assessing right heart function, clinicians can obtain critical information regarding cardiac output and fluid status, enabling tailored treatment plans for complex medical issues. In contrast, other options do not align with the primary function of the Swan-Ganz catheter. For example, while fluid resuscitation is indeed a critical aspect of management in several clinical scenarios, the catheter is not specifically designed for that purpose. Additionally, the assessment of long-term heart rhythm is typically conducted using different monitoring tools like telemetry or Holter monitors, rather than a Swan-Ganz catheter. Lastly, while peripheral vascular disease affects circulation, the Swan-Ganz catheter is not used for managing non-cardiac vascular conditions. Thus, the only appropriate use listed within the options is the evaluation of right heart function in critically ill patients.
