215 – Noninvasive Cardiac Ouput – NICO100C

Cardiac Output can be noninvasively determined by employing electrical bioimpedance measurement techniques. Electrical bioimpedance is simply the characteristic impedance of a volume of tissue and fluid. In the case of Cardiac Output measures, the relevant tissue includes the heart and the immediate surrounding volume of the thorax. The relevant fluid is blood.

ICG Setup Notes

  • This app note references LEAD130 four-clip cardiac output lead and EL506 strip electrodes, which have been discontinued.
  • The recommended replacement is EL500 spot electrodes x8 + LEAD1100C x8 + CBL204 Y-adapter x4 + MEC110C extension.

Note: To record NICO using an MP36R, MP36, MP35, or MP45, see SS31LA.

Associated Applications

  • Psychophysiology - Record and analyze BP, ECG, HRV, EDA, EMG, EEG, EOG, RSP, etc. Interface to stimulus presentation programs...use automated analysis routines to easily score and analyze data.
  • ICG: Impedance Cardiography/Cardiac Output - Record cardiac output, thoracic impedance changes, or any kind of bioimpedance signal. Use AcqKnowledge for a fully automated ICG analysis and dZ/dt waveform classifier.
  • Sleep Studies - Long term recordings with up to 16 channels of data. Record EEG, EOG, EMG, respiration, temp., sound, limb position and more. Filter out EEG frequencies to score sleep stages.
  • Cardiovascular Hemodynamics - Hardware for human and animals. Measure continuous BP, ECG, stroke volume, cardiac output, PPG, etc. For animal and tissue look at acute and chronic dose-response.
  • Exercise Physiology - Examine ventilation, oxygen uptake, carbon dioxide production, biopotentials, temp., and biomechanical signals simultaneously. Record wirelessly with BioNomadix.
