Basic Surgery MCQ 014

Which of the following statements about continuous cardiac output monitoring are true?

A. Continuous cardiac output monitoring may unmask events not detected by intermittent cardiac output measurements.

B. Continuous cardiac output monitoring by the thermodilution method requires continuous infusion of fluid injectate at a constant rate and temperature.

C. The major advantage of the Fick method over the thermodilution method of calculating cardiac output is that it is noninvasive, requiring only the determination of oxygen consumption by respiratory gas analysis.

D. The technique of thoracic electrical bioimpedance utilizes sensors to determine stroke volume by detecting changes in resistance to a small, applied alternating current.
