Noninvasive Doppler ultrasonography for assessing cardiac function: can it replace the Swan-Ganz catheter?
Cardiac function, including cardiac index (CI), traditionally has been measured by a pulmonary artery catheter (PAC). A noninvasive alternative for measuring cardiac function would offer obvious advantages. ⋯ Doppler UTS correlates well with PAC measurements of CI. This noninvasive modality is an accurate and safe alternative to PAC.
