AC mode indicates that a high-pass (HP) filter has been applied to the signal that you are recording. An HP filter removes the low-frequency components of a signal. The most common AC mode settings on BIOPAC amplifiers are 0.5 Hz HP and 0.05 Hz HP. In AC mode, the signal is centered around zero.
AC mode is useful in studying changes in the signal. AC mode is not appropriate for recording absolute measures or for detecting the baseline level of the signal.
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 […]
MIT and Harvard researchers developed a new technique to expand ventilator capacity Individualized System for Augmenting Ventilator Efficacy (iSAVE): A Rapidly deployable system to expand ventilator capacity “The iSAVE is a rapidly deployable solution in response to the urgent shortage of mechanical ventilators for respiratory support during the COVID-19 pandemic. In contrast to previously described […]
