Abstract
Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. In some aspects, a system and method can include obtaining values for depths of a plurality of the chest compressions and information about a physiological parameter of the person and providing periodic feedback to a user about chest compressions performed by the user based at least in part on the values for the depths of the plurality of the chest compressions and a target compression depth.
Claims25
A method for providing adaptive Cardiopulmonary Resuscitation (CPR) treatment to a person in need of emergency assistance, the method comprising:
- obtaining, by a portable computing unit, values for depths of a plurality of the chest compressions;
- obtaining, by the portable computing unit, information about a physiological parameter of the person selected from t he group consisting of end-tidal carbon dioxide, arterial pressure, volumetric carbon dioxide, and blood pressure;
- providing, at a first rate, periodic feedback to a user about chest compressions performed by the user based at least in part on the values for the depths of the plurality of the chest compressions and a target compression depth, and
- periodically determining, at a second rate that is slower than the first rate, whether to adjust the target compression depth based at least in part on the information about the physiological parameter of the person;
- upon determining to adjust the target compression depth based at least in part on the information about the physiological parameter of the person, storing an updated target compression depth;
- and
- providing, at the first rate, periodic feedback to the user about chest compressions performed by the user based at least in part on the values for the depths of the plurality of the chest compressions and the updated target compression depth.
An external defibrillator, comprising:
- one or more sensors arranged to contact a patient and obtain measurements regarding chest compressions performed on the patient;
- one or more additional sensors arranged to contact a patient and obtain measurements regarding a physiological parameter of the patient selected from the group consisting of end-tidal carbon dioxide, arterial pressure, volumetric carbon dioxide, and blood pressure;
- a feeedback device configured to provide, at a first rate, periodic feedback to a user about chest compressions performed by the user based at least in part in the values for the depths of the plurality of the chest compressions and a target compression depth, and
- a processor connected to memory that stores computer instructions for:
- periodically determining, at a second rate that is slower than the first rate, whether to adjust the target compression depth based at least in part on the information about the physiological parameter of the person, so that multiple instances of feedback about chest compressions performed by the user are provided to the user for each instance of determining whether to adjust the target compression depth;
- and
- upon determining to adjust t he target compression depth based at least in part on the information about the physiological parameter of the person storing an updated target compression depth;
- and
- wherein the feedback device is further configured to provide periodic feedback to a user about chest compressions performed by the user based at least in part on the values for the depths of the plurality of the chest compressions and the updated target compressions depth.
A method for providing adaptive Cardiopulmonary Resuscitation (CPR) treatment to a person in need of emergency assistance, the method comprising:
- obtaining, by a portable computing unit, values for depths of a plurality of the chest compressions;
- obtaining, by a portable computing unit, information about a physiological parameter of the person selected from the group consisting of end-tidal carbon dioxide, arterial pressure, volumetric carbon dioxide, and blood pressure;
- displaying a graphical representation of the information about the physiological parameter including trend data associated with a trend in values of the physiological parameter;
- providing periodic feedback to a user about chest compressions performed by the user based at least in part on the values for the depths of the plurality of the chest compressions and a target compression depth, and
- determining whether to adjust the target compression depth based at least in part on the information about the physiological parameter of the person;
- upon determining to adjust the target compression depth based at least in part on the information about the physiological parameter of the person, storing an updated target compression depth;
- and
- providing feedback to the user about chest compressions performed by the user based at least in part on the values for the depths of the plurality of the chest compressions and the updated target compression depth.
