Abstract
An apparatus for and method of monitoring respiration of a patient using impedance changes of the body to indicate respiration events. Cardiac related artifacts are suppressed by separately processing an EKG signal. Transient artifacts are accommodated by modifying the pass band of the respiration monitoring circuitry to selectively attenuate the signal within the frequency range of the transient artifact.
