What it is?
Impedance cardiograph, also called thorax electrical impedance, was initially used by NASA's Apollo program, for the hemodynamic monitoring of its astronauts. After many years, the new generations of this system made it possible to assess in real time, in a continuous, reproducible way and at a low cost, the different hemodynamic parameters of a patient in a non-invasive way. This is how cardiac output, cardiac index, contractility, global intravascular blood flow per minute and total chest fluid content can be obtained.
The method has been validated for use in different clinical contexts and it´s as accurate as the data obtained invasively, with the thermodilution catheter. Among these are heart failure, pulmonary hypertension, pulmonary arterial hypertension, systemic arterial hypertension and critically ill patients in the intensive care unit, with continuous and real-time monitoring of the parameters mentioned
In addition to being cost effective, this method has the advantage of not using catheters invasively, which avoid complications such as infections, hemorrhages, bruises, perforations and others.
Procedure
- Electric chest bioimpedance uses the patient's chest as an impedance transducer
- The patient is connected through a cable and 8 disposable electrodes, through which high frequency and low amplitude energy is emitted and the other 4 receiving electrodes, capture the difference of the energy that enters and receives, measuring the electrical resistance of the thorax produced by variations in the volume of the aorta during the cardiac cycle.
- No special preparation is required before the study.
- It can be carried out at the bedside of the patient, in hospital or in the patient house.
