Anesthesia Technologist Practice Exam

What should be monitored continuously after PA catheter placement?

1. Blood pressure readings

2. ECG changes

3. Pulmonary artery pressures

4. Oxygen saturation levels

The correct answer is: Pulmonary artery pressures

Continuous monitoring of pulmonary artery pressures after the placement of a pulmonary artery (PA) catheter is essential as it provides critical information about a patient’s hemodynamic status. This catheter is specifically designed to assess the pressures within the pulmonary artery and the right heart chambers, which helps in evaluating cardiac function and fluid management. Monitoring these pressures allows anesthesiologists and other healthcare providers to make informed decisions regarding treatment and interventions. Abnormal readings can indicate issues such as heart failure, pulmonary hypertension, or fluid overload, which can significantly affect patient outcomes. By continuously monitoring these pressures, the medical team can promptly identify any adverse changes and respond appropriately. While monitoring blood pressure, ECG changes, and oxygen saturation levels are important components of patient care, they do not provide the specific insights into pulmonary circulation and cardiac pressures that the PA catheter does. Consequently, pulmonary artery pressures are critical for the management of patients in critical care settings or during complex surgical procedures.
