A system comprising: a wrist-worn device configured to be worn on the wrist of a rescuer performing cardiopulmonary resuscitation (CPR), the wrist-worn device including: one or more sensors coupled with the wrist-worn device, the one or more sensors being configured to sense one or more parameters indicative of a fatigue level of the rescuer; and a sensor interface configured to provide the sensed parameters to one or more external computing devices via an interface; and a wearable computing device configured to be worn by a rescuer, the wearable computing device including: a device interface for receiving information related to CPR; and a display for displaying an indication of the received information.

Apparatus for automatic delivery of chest compressions and ventilation to a patient, the apparatus including: a chest compressing device configured to deliver compression phases during which pressure is applied to compress the chest and decompression phases during which approximately zero pressure is applied to the chest a ventilator configured to deliver positive, negative, or approximately zero pressure to the airway; control circuitry and processor, wherein the circuitry and processor are configured to cause the chest compressing device to repeatedly deliver a set containing a plurality of systolic flow cycles, each systolic flow cycle comprising a systolic decompression phase and a systolic compression phase, and at least one diastolic flow cycle interspersed between sets of systolic flow cycles, each diastolic flow cycle comprising a diastolic decompression phase and a diastolic compression phase, wherein the diastolic decompression phase is substantially longer than the systolic decompression phase.

An example system includes a first wearable computing device, and at least one additional wearable computing device. The first wearable computing device is configured to retrieve information regarding a series of tasks to be performed in treating a patient in cardiopulmonary arrest. The information includes, for each task, an indication of a user to perform the task, an indication of a time point to perform the task. The first wearable computing device is further configured identify one or more subsets of the information, and transmit each subset to a different corresponding one of the additional wearable computing devices. Each additional wearable computing device is configured to receive, from the first wearable computing device, at least one of the one or more subsets of the information, and output, for each task within a received subset, a corresponding prompt to perform the task at the respective time point associated with the task.

A feedback device for an acute care provider includes: at least one motion sensor; a haptic output component for providing feedback having a varying haptic pattern to the acute care provider regarding performance of a resuscitation activity; and a controller. The controller can be configured to receive and process a signal representative of performance of the resuscitation activity from the at least one motion sensor, compare the acute care provider's performance of the resuscitation activity to a target performance of the resuscitation activity, and cause the haptic output component to provide haptic feedback to the acute care provider by changing the haptic pattern based, at least in part, on the signal from the at least one motion sensor and the comparison of the acute care provider's performance to the target performance of the resuscitation activity. The device can be adapted to be wrist-worn by the acute care provider.
