International Classification:

Abstract:

A system for assisting a rescuer in providing cardiopulmonary resuscitation (CPR) chest compressions includes a motion sensor configured to generate motion sensor signals indicative of chest motion and a defibrillator. The defibrillator includes a processor and a display screen configured to provide CPR feedback and defibrillation information. The processor is configured to receive the motion sensor signals, analyze the motion sensor signals for features characteristic of a chest compression delivery type to distinguish between chest compression delivery types comprising manual compression, non-automated ACD, and automated ACD, and selectively provide the CPR feedback at the display screen based on an identification of the chest compression delivery type such that the CPR feedback includes a plurality of CPR parameters for the manual compression delivery type and remove at least portions of the CPR parameters from the display screen for the non-automated ACD and the automated ACD compression delivery types.

A61B 5/087
A61B 5/00
A61N 1/39
A61M 16/06

Abstract:

A medical ventilation monitoring system is provided. The system includes: a patient ventilation unit defining an airflow path, and arranged so that when the unit is applied to a patient, the airflow path is in fluid communication with the patient's airway. The patient ventilation unit includes: an airflow sensor positioned to sense the presence of ventilation airflow to or from the patient and a communication link. The system also includes at least one processor arranged to communicate with the ventilation unit by the communication link. The at least one processor is configured to: provide an initial treatment protocol for providing care to the patient, receive data regarding a current condition of the patient from the ventilation unit, and determine an updated treatment protocol. The updated treatment protocol includes applying ventilation at an updated ventilation volume or at an updated ventilation rate based on information from the airflow sensor.

International Classification:

G09B 23/28
A61H 31/00
A61N 1/39

Abstract:

An example of a system for assisting a rescuer in providing CPR includes a motion sensor configured to generate signals indicative of chest motion during CPR chest compressions, and a defibrillator including a display screen configured to provide CPR feedback and defibrillation information and a processor configured to receive the signals, generate a compression waveform based on the signals, detect, in the compression waveform, features characteristic of chest compressions, compare the detected features to a predetermined criterion that distinguishes between manually delivered and compressions delivered by an automated compression device, and selectively provide the CPR feedback based on whether the compressions are the manually delivered or the automated compressions, where the selective provision of the CPR feedback includes displaying CPR parameters for the manually delivered compressions, and a removing from the display screen at least one CPR parameter of the CPR parameters for the automated compressions.

International Classification:

A61N 1/04

A61N 1/39

Abstract:

A system for facilitating resuscitation includes: a first electrode assembly having a therapy side and a first motion sensor; a second electrode assembly having a therapy side and a second motion sensor; processing circuitry operatively connected to and programmed to receive and process signals from the first and second motion sensors to estimate at least one of a chest compression depth and rate during administration of chest compressions and to compare the chest compression depth or rate to a desired range; and an output device for providing instructions to a user to administer chest compressions based on the comparison of the estimated chest compression depth or rate to the desired range. One or both of the electrode assemblies may be constructed so that the conductive therapeutic portion is able to maintain substantial conformance to the anatomy of the patient when coupled thereto. For example, at least a portion of the flexible electrode pad may be able to flex from a more rigid sensor housing, or the sensor housing itself may be relatively small compared to the flexible electrode pad so as not to cause lift off of the therapeutic side from the patient.
