Abstract
An example method includes administering a treatment to a subject during a time interval. The example method further includes receiving, from an external device, a first signal indicating a physiological parameter of the subject detected during the time interval; removing, from the physiological parameter, an artifact associated with the treatment; and in response to removing the artifact from the physiological parameter, outputting a second signal indicating the physiological parameter.
Claims20
A system, comprising:
- a monitor configured to:
- generate an electrocardiogram (ECG) by detecting an electrical signal indicative of cardiac activity of a subject;
- and
- to transmit a first signal indicating the ECG of the subject;
- and
- a mechanical chest compression device comprising:
- a compressor configured to apply chest compressions to the subject;
- a transceiver configured to receive the first signal indicating the ECG of the subject;
- and
- a processor configured to:
- identify a frequency at which the compressor applies the chest compressions to the subject;
- generate a comb filter comprising a first band overlapping the frequency and second bands overlapping harmonics of the frequency;
- remove a chest compression artifact from the ECG by applying the comb filter to the ECG;
- and
- in response to removing the chest compression artifact from the ECG, cause the transceiver to transmit a second signal indicating the ECG of the subject omitting the chest compression artifact.
