A pressure transducer connected to a catheter filled with saline is introduced through an artery into the patient's right atrium (RA). The catheter line then emerges from the patient's body and droops vertically below the bed and down from the RA by 50 cm then rises up to the pressure transducer hanging on a pole at 100 cm above the RA. The pressure transducer reads a blood pressure of 60/30 mmHg. Draw the diagram of this situation. What is the true blood pressure in the RA? Density of saline is 1.009 g/cm^3 density of blood is 1.055 g/cm^3. Please try to explain!
