Abstract
Among other things, in one aspect, we describe a system for assisting with cardiopulmonary resuscitation (CPR). The system includes at least one sensor; and one or more processors configured for calculating a chest compliance relationship based on data received from the at least one sensor, and determining a neutral position of chest compression based at least in part on a feature of the chest compliance relationship. The system can take the form of an active compression-decompression device.

(canceled)
A system for assisting with cardiopulmonary resuscitation (CPR), the system comprising:
- at least one force sensor configured to detect force applied to a patient's chest;
- at least one displacement sensor configured to detect displacement of the patient's chest;
- and
- one or more processors and a non-transitory computer readable storage medium encoded with a computer program comprising instructions that, when executed, cause the one or more processors to perform operations comprising:
- receiving force data captured by the at least one force sensor during active compression-decompressions delivered to the patient's chest,
- receiving displacement data captured by the at least one displacement sensor during the active compression-decompressions delivered to the patient's chest,
- detecting, based on the received force data and received displacement data, an elevated risk of rib fracture in the patient, and
- providing an indication of the elevated risk of rib fracture in the patient.
A system for assisting with cardiopulmonary resuscitation (CPR), the system comprising:
- an active compression-decompression (ACD) device configured to be affixed to a chest of a patient;
- at least one force sensor operably coupled with the ACD device;
- and
- one or more processors and a non-transitory computer readable storage medium encoded with a computer program comprising instructions that, when executed, cause the one or more processors to perform operations comprising:
- calculating a chest compliance relationship based on force data captured by the at least one force sensor during active compression-decompressions delivered via the ACD device,
- detecting, based on the calculated chest compliance relationship, one or more changes to chest compliance of the patient, and
- providing at least one indication when the detected one or more changes to chest compliance of the patient indicates a risk of rib fracture in the patient.
