<prompt> The most recent advance in noninvasive cardiac output monitoring is use of:PA catheterThermodilution techniqueEchocardiographyElectrical impedance cardiography technology  <response>: D i.e. Electrical impedance cardiograph technology- PA catheter thermodilution technique are invasive procedure.- Echo is noninvasive old technique to measure cardiac output- Recent noninvasive advance to measure C.O. is electrical impedance Cardiographs technology.
