1. A method for providing adaptive Cardiopulmonary Resuscitation (CPR) treatment to a person in need of emergency assistance, the method comprising:
- obtaining data representing chest compression depth from at least one sensor located on a chest of a person receiving CPR and arranged to move in conjunction with chest compressions performed by a user;
providing, at a first rate, periodic feedback to the user about the chest compressions performed by the user based at least in part on data obtained from the at least one sensor and a target compression depth,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 a trend represented in obtained information about a physiological parameter not based on an ECG signal of the person,upon determining to adjust the target compression depth, providing information to the user about an updated target compression depth and the obtained data representing chest compression depth.

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.

13. 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 not based on an ECG signal of the patient; feedback 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 on the values for the depths of the chest compressions and a target compression depth; and a processor to execute instructions, stored in a memory, 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 a trend represented in the information about the physiological parameter not based on an ECG signal of the patient; and upon determining to adjust the target compression depth, providing information to the user about the updated target compression depth; wherein the feedback device is further configured to provide periodic feedback of the performed chest compressions based at least in part on the values representing the depths of the chest compressions and the updated target compression depth. - View Dependent Claims (14, 15, 16, 17)

18. A system comprising:
-
an external defibrillator; a feedback 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 on obtained values for the depths of the chest compressions and a target compression depth; and a processor to execute instructions, stored in a memory, 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 a trend represented in obtained information about a physiological parameter not based on an ECG signal of a person; and upon determining to adjust the target compression depth, providing information to the user about an updated target compression depth, wherein the feedback device is further configured to provide periodic feedback of the performed chest compressions based at least in part on the values for the depths of the chest compressions and the updated target compression depth. - View Dependent Claims (19, 20, 21, 22)
