"The
data showed that useful hemodynamic data may be obtained from
TEB; this determination is rapid, without risk, and of markedly
lowe cost. Importantly, TEB data attenuated PAC placement in
at least 71% of patients; of the PACs that were placed, most
were due to physician preference alne and in each case, the data
obtained wit the PAC corresponded to the data obtained with TEB
measurement." |

"In
this double-blind, crossover study the authors have validated
stroke volume determination by impedance cardiography against
the pulsed Doppler echocardiographic method in elderly hypertensives.
They found a good correlation between the stroke volume values
obtained by the two methods over a range of values from 30 to
130 mL. The coefficient of linear regression was about .95 at
each visit. The mean of the differences was -0.73 mL with a standard
deviation of 8.46. From the distribution of the data around the
mean plot it appears that, in comparison with pulsed Doppler,
impedance cardiography tends to slightly underestimate stroke
volumes of greater than 90 mL and to overestimate values of less
than 50 mL. The results of this study indicate that impedance
cardiography may represent a reliable alternative to pulsed Doppler
echocardiography for the noninvasive estimation of cardiac output
at rest in elderly patients." |

"Direct
expenditures in the treatment of heart failure are expected to
exceed $18 billion in the United States in 1998. The greatest
portion of these costs is attributable to the frequency of acute
heart failure episodes that require emergency treatment and hospital
admission. Thoracic electrical bioimpedance monitoring provides
the mechanism to optimize medication dosages safely in the patient
with congestive heart failure per the Agency fo Health Care Policy

"Even
experience observers often have difficulty deciding on therapeutic
options for patients with advanced heart failure. Inaccurate
decisions can quickly lead to worsened clinical status, hypotension,
azotemia, and emergent admission. Measurement of central hemodynamics
can often guide these difficult decisions. In our series of patients,
applications of ICG complemented clinical skill and judgment
and allowed for improved clinical decision making. ICG is an
important tool for assessing outpatients with advanced heart
failure." ICG evaluation attenuated hospital admission in
6 of 8 cases (86%), helped improve volume status based on diuretic
decisions in 8 of 9 patients (89%), and helped intensify pharmacological
therapy in 20 of 20 patients (100%). |

"…noninvasive
measurement of CO using TEB in patients with LVAD is accurate
and provides an assessment of total CO. These measurements were
consistently accurate across a wide range of ages and post-operative
days. Based on this reliability we have been successful in weaning
patients using a novel new LVAD weaning protocol. Further, using
TEB avoided additional risk and expense in our patients with
LVADs. TEB measurement is a useful tool in assessing CO in patients
with LVADs as well as providing the ability to wean patients.
TEB is also a useful tool in assessing degree of recovery of
left ventricular function during periods of reduced LVAD support.
Utilization of TEB also reduces cost and risk for these patients." |

"…noninvasive
hemodynamic monitoring, through the technology of thoracic electrical
bioimpedance, is an emerging medical trend based on clinical
efficacy, patient safety, and cost-effectiveness. TEB is a valuable
adjunct to patient assessment and treatment across health care
settings and provides the clinican with a chance to "view
within." |
