Abstract
An example method is performed by a first medical device and includes generating first data indicating a physiological parameter of a subject; generating a filter configured to remove an artifact associated with a treatment; and generating second data by applying the filter to the first data. The example method further includes determining that a second medical device is administering the treatment to the subject. In response to determining that the second medical device is administering the treatment to the subject, the first medical device outputs an indication that filtering is available; receives an input signal selecting the filtering; and in response to receiving the input signal, displays the second data.
Claims20
A monitor-defibrillator, comprising:
- a detection circuit configured to detect an electrocardiogram (ECG) signal of a subject;
- an analog-to-digital converter (ADC) configured to convert the ECG signal into unfiltered ECG data;
- a display;
- an input device configured to receive a first input signal and a second input signal from a rescuer;
- a discharge circuit configured to output an electrical shock to the subject;
- and
- a processor configured to:
- cause the display to visually present the unfiltered ECG data;
- determine that a mechanical chest compression device is administering chest compressions to the subject at a frequency;
- in response to determining that the mechanical chest compression device is administering the chest compressions to the subject at the frequency:
- generate filtered ECG data by applying a comb filter to the unfiltered ECG data, the comb filter rejecting the frequency and harmonics of the frequency;
- cause the display to visually present a message indicating that the filtered ECG data is available;
- and
- in response to the input device receiving the first input signal, cause the display to visually present the filtered ECG data;
- determine that the filtered ECG data is indicative of ventricular fibrillation (VF);
- and
- in response to determining that the filtered ECG data is indicative of VF:
- cause the display to visually present an instruction to defibrillate the subject;
- and
- in response to the input device receiving the second input signal, cause the discharge circuit to output the electrical shock.
