A nurse is preparing to inflate the balloon located in the pulmonary artery. What is the purpose of inflating the balloon?
1. When inflated, the catheter indirectly measures pressures in the left side of the heart.
2. When inflated, the catheter measures cardiac output through thermodilution.
3. When inflated, the catheter measures the pressure in the right side of the heart.
4. When inflated, the catheter indirectly measures the cardiac index.
When inflated, the catheter indirectly measures pressures in the left side of the heart.
Rationale: Inflating the balloon in the pulmonary artery catheter indirectly measures pressures in the left side of the heart. Cardiac output is measured though a thermistor located within the catheter. The cardiac index is a calculation of the cardiac output divided by the body surface area.
