Respiration Monitoring

For bioimpedances measured across the thorax using the EBI100C, a small impedance change is observed with each inspiration and expiration. For respiration monitoring, electrodes are placed across the mid-thorax along the mid-axillary line. Filtering can be employed in AcqKnowledge to minimize motion artifacts. Because the EBI100C measures the thoracic impedance directly, the module can measure arbitrarily low breathing rates. When initially calibrated against a pneumotach, the EBI100C can also be used to estimate ventilation.

New Citations | Utilizing VR and AcqKnowledge to Reduce Stress

 Impact of Green Space on Stress Reduction Research studies show that the increased exposure of urbanization, traffic noise and pollution has been correlated with increasing levels of stress. However, do greener, more natural environments provide the opposite effect, restoring human well-being and contributing in stress reduction? Researchers compared user experiences in Virtual Reality (VR) scenes […]
