What is the primary purpose of using the Swan-Ganz catheter?

• A. To provide nutrition
• B. To monitor cardiac function
• C. To administer medication
• D. To drain urine

Answer: (B)

The primary purpose of using the Swan-Ganz catheter is to monitor cardiac function. This specialized catheter is designed to be inserted into the pulmonary artery, allowing for direct measurement of hemodynamic pressures. It provides valuable information about the heart's performance, including pulmonary artery pressure, pulmonary capillary wedge pressure, and cardiac output. This data is critical for the management of patients with various cardiac conditions, providing insight into their cardiovascular status and helping guide treatment decisions.

Understanding the hemodynamics of a patient is essential in acute and critical care settings, and the Swan-Ganz catheter is an important tool for giving healthcare providers a clearer picture of cardiac function. It is not intended for providing nutrition, administering medications, or draining urine, which are functions associated with other types of catheters or medical devices.
