CONTEXT-SENSITIVE CHEST COMPRESSION FRACTION MEASUREMENT FOR CPR QUALITY ASSESSMENT

摘要

Devices, systems, software and methods for CPR quality assessment. Patient data is received that may be derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. Then a figure of merit (FOM) can be computed from the data in the computation, at least one pause can contribute a penalty to the FOM. The penalty has a value determined from at least one control factor, other than a constant linear dependence on the duration of the pause. This way, pauses can incur penalties to the FOM computation depending on their context, instead of merely their duration. For example, a penalty can escalate non-linearly if its pause becomes unduly long, or if it follows a set of chest compressions that was unduly short. As such, a better CPR quality assessment is achieved.

主权项

1. A system for CPR feedback, comprising:
a sensor configured to be placed on a patient's chest and detect a time displacement of the chest as the patient is receiving sets of CPR chest compressions that are separated by pauses; a base device having a user interface, and operatively coupled to input from the sensor patient data from the detected time displacement of the chest; and processor configured to:
input patient data derived from a session of administering to a patient sets of CPR chest compressions that are separated by pauses, andcompute from the patient data a figure of merit (FOM), in which at least a certain one of the pauses contributes a certain penalty to the FOM, the certain penalty having a value determined from at least one control factor other than a constant linear dependence on a duration of the certain pause, and in which the user interface is configured to output a value of the FOM.
