Question 1

Which parameter is measured by a pulmonary artery catheter to assess left heart preload?

Accepted Answer

Pulmonary artery wedge pressure

Answer

Pulmonary artery wedge pressure (PAWP) reflects left atrial pressure and is used as a surrogate for left ventricular end-diastolic pressure.

Question 2

What is the normal range for cardiac index in a healthy adult at rest?

Accepted Answer

2.2–4.0 L/min/m²

Answer

Cardiac index (CI) is cardiac output normalized to body surface area, with a normal range of 2.2–4.0 L/min/m² in adults.

Question 3

In the ICU, which arterial waveform finding suggests hypovolemia during positive pressure ventilation?

Accepted Answer

Pulse pressure variation >13%

Answer

Pulse pressure variation (PPV) >13% during mechanical ventilation is a reliable dynamic indicator of fluid responsiveness indicating hypovolemia.

Question 4

Which mixed venous oxygen saturation (SvO2) value indicates adequate global oxygen delivery in a critically ill patient?

Accepted Answer

≥65%

Answer

An SvO2 ≥65% generally indicates adequate global oxygen delivery relative to consumption; values below this suggest oxygen debt.

Question 5

What does the Stewart-Hamilton equation calculate when using thermodilution?

Accepted Answer

Cardiac output

Answer

The Stewart-Hamilton equation calculates cardiac output by analyzing the temperature change over time following cold saline injection into the pulmonary artery catheter.
