BIOPAC released a new application note that explains how to optimize ECG R-R interval data for Heart Rate Variability studies by using a template matching approach. It also explains how to identify erroneous R-R interval values caused by signal artifact and shows methods for correcting the errors by using the tools in the AcqKnowledge software. If these guidelines are followed and subject movement is minimized it is reasonable to expect virtually no artifacts in the data.
The following screenshot is taken from a 9 min ECG recording where the subject sneezed, moved in the chair, twisted his body, stood up and sat down, moved his hands, etc., all with no artifact (observe the consistent R-R interval waveform on the bottom).
The Ventilator Validation Kit supports new prototype development, existing design validation for production testing, mobile field testing and verification, and other uses where accurate pressure and flow measurements are critical. The Ventilator Validation Kit provides ventilator manufacturers and prototype developers with a complete solution for validating new medical/hospital-grade ventilator products intended for human use. The VVK100-SYS includes […]

Physiological Lung Testing in the MRI to Find Damage from Military Deployments Our military veterans who served overseas in the middle east often come home with scars both seen and unseen. For some vets, unfortunately, these scars can take the form of lung damage sustained due to sandstorms, burn pits, and other high toxicity situations apparent […]
