摘要： A system for assisting a rescuer in providing resuscitative treatment to a victim is described. An example of the system includes a processor configured to detect compression waveform features characteristic of manual chest compressions, automated chest compressions, and mechanically assisted active compression-decompression (ACD) chest compressions, an output device communicatively coupled to the processor, and a motion sensor, communicatively coupled to the processor and configured to generate signals indicative of motion of the victim's chest during chest compressions. The processor is further configured to receive the signals indicative of the motion of the chest, generate a compression waveform based on these signals, identify the compression waveform as one of a manual, an automated, and a mechanically assisted ACD chest compression waveform based on compression waveform features in the compression waveform, and control the output device to selectively provide chest compression feedback to the rescuer based on the identified compression waveform.

摘要： An apparatus is described that includes a medical device including an output device, a memory, and a processor, electrodes configured to provide an electrical impedance signal to the processor, wherein the impedance signal corresponds to an impedance measured at a patient's chest, and sensors configured to provide a motion signal to the processor, wherein the motion signal is indicative of chest compressions performed during a cardiopulmonary resuscitation (CPR) treatment of the patient, wherein the processor is configured to receive the impedance signal and the motion signal and to execute instructions to determine threshold values of a signal processing algorithm for the impedance signal, adaptively modify the threshold values in response to motion signal changes, apply the modified threshold values to the impedance signal to identify airflow activities represented in the signal, calculate characteristics of the airflow activities, and provide an output indicative of the characteristics of the airflow activities.

摘要： A system for providing role-based data feeds for a plurality of patient caregivers includes a portable central device and a patient data display screen. The central device is configured to obtain the medical data via one or more sensors and/or electrodes configured to couple to the patient and provide the medical data to mobile devices, optionally as multiple role-based data feeds. The central device may include software and hardware configured to feed the medical data to the mobile devices via multiple role-based data feeds. The patient data display screen is configured to display the medical data. Each mobile device may identify an associated type of medical data by displaying a screen enabling a caregiver to select the associated type of medical data based on their role, or may receive a respective role-based data feed from the central device. Each mobile device is configured to display the received medical data.
