Which of the following is the function of the transducer in the invasive vascular monitoring system?

• Measure the flow of fluid in the catheter.
• Convert the fluid pressure to an electrical signal.
• Connect to the thermistor to measure cardiac output.
• Amplify the electrical signal so it may be seen on the monitor.

Which of the following measurements can be used to estimate right ventricular preload?
