The value of noninvasive cardiac output (Qt) monitoring
lies first and foremost in its convenient, low-risk application to a
variety of clinical settings. The noninvasive thoracic electrical
bioimpedance monitor is well suited to hospital bedside, physician’s
office, emergency department, ICU, and operating room settings. Thus,
Shoemaker et al, in this issue of CHEST (see page 528), were
able to utilize impedance cardiography (ICG) for early comprehensive
cardiovascular assessment and trending of acute trauma victims.
