A new respiration monitor was developed with this paper, which can monitor tidal volume continuously based on the impedance technique as well ad ECG at the same time. Advanced digital storage display technique and modular hardware design are adopted in this system. One by one calibration method was introduced to solve problem of individual differences in… (More)
In this paper an ECG amplifying circuit is comprehensively presented. This circuit has all the necessary functions which include isolated ground, programmable ECG lead and filter band, programmed gain, rapid baseline restoring, anti defibrillating electrical shock, anti interference of high frequency electrotome etc.
