Associated Applications
- 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.
- 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.
- ECG: Cardiology - Connect up to 16 ECG input leads with MP160 system. Use automated analysis features for HRV, RSA, to classify heartbeats, identify arrhythmias, and perform ECG averaging.
- Plethysmography - Record PPG, measure BP indirectly, look at appendage size variations, and perform sexual arousal studies using BIOPAC or 3rd-party transducers.
