Abstract：Cardiac output is one of the most important physiological indicators to evaluate cardiovascular function, which can
be used in the diagnosis, treatment and prognosis improvement of critically ill patients, patients with heart failure and patients
after major surgery. There are many clinical cardiac output monitoring techniques, but each has its advantages and disadvantages:
invasive methods, such as thermodilution, which is accurate but can cause some damage to the body; minimally invasive or noninvasive
procedures, such as cardiac impedance, which is non-invasive to the body but need to be more accurate. Currently, there
is no monitoring device can meet all clinical needs, so clinicians must choose the appropriate measurement for each patient. With
the widespread use of non-invasive cardiac output monitoring technology in clinical practice, exploring a non-invasive, real-time,
accurate continuous cardiac output monitoring technique is significant in treating acute and critical patients. This paper reviewed
the principles, applications, limitations, and research trends of existing cardiac output measurement methods. It hopes to provide a
comparative analysis to provide a reference basis for choosing cardiac output monitoring methods for critically ill patients.
