An external defibrillator system for assisting manual delivery of chest compressions and ventilations to a patient by a rescuer as cardiopulmonary resuscitation (CPR) includes a speaker, and a processor, memory, and associated circuitry coupled to the speaker. The processor is configured to initiate prompting for the chest compressions and the ventilations manually delivered to the patient by the rescuer as CPR, control the speaker to generate first auditory cues for the chest compressions, and control the speaker to generate second auditory cues for the ventilations with a different sound than the first auditory cues for the chest compressions. The first auditory cues and the second auditory cues assist the rescuer in timing the delivery of the chest compressions and the ventilations.

A defibrillator assesses cardio pulmonary resuscitation carried out on a subject and provides feedback. The defibrillator measures bio signals of the subject, determines when CPR is required and produces a start signal and determines and when CPR is no longer required and produces a stop signal. A measurement system measures compression signals during CPR chest compressions, a CPR assessment system receives the CPR start signal and the CPR stop signal and receives compression signals. The defibrillator uses the compression signals to establish a first CPR performance measurement, set a performance baseline of the person equal to the first CPR performance measurement of the person, compare the further CPR performance measurement of the person with the CPR performance baseline of the person, produce a feedback signal and set the CPR performance baseline of the person equal to the further CPR performance measurement of the person and return to earlier operations.

A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.

A medical system includes a manual patient ventilation unit defining an airflow path arranged so that when the unit is applied to a patient the airflow path is in fluid communication with the patient's airway. The patient ventilation unit includes a ventilation bag configured to enable manual ventilation of the patient by a rescuer, an airflow sensor in the airflow path positioned to sense the presence of ventilation airflow and measure a gas flow rate in the airflow path, and a pressure sensor in the airflow path positioned to sense gas pressure in the airflow path. The system also includes a processor arranged to receive data generated by the airflow sensor and the pressure sensor and determine one or more ventilation quality parameters based at least in part on a gas flow volume calculated based on the sensed gas flow rate and gas pressures.

Apparatus for automatic delivery of chest compressions and ventilation to a patient. The apparatus includes 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 including 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 including a diastolic decompression phase and a diastolic compression phase, wherein the diastolic decompression phase is substantially longer than the systolic decompression phase.

An external defibrillator system is provided. The system includes: a graphical display; one or more sensors for obtaining data regarding chest compressions performed on a patient; and a controller configured to display on the graphical display numeric values for depth and/or rate of the chest compressions based upon the data from the one or more sensors. A method for using an external defibrillator including the steps of: obtaining data regarding chest compressions perforated on a patient; and displaying on a graphical display screen of the defibrillator numeric values for depth and/or rate of the chest compressions based upon the data is also provided.

A patient-coupled resuscitation device for use with a plurality of medical devices is provided. The resuscitation device includes a portion configured to provide treatment, a connector configured to connect the resuscitation device to one of a first medical device and a second medical device, and a housing including a memory and associated circuitry. The memory and associated circuitry is configured to store a device identifier to identify the resuscitation device; receive medical treatment information from the first medical device, the medical treatment information including at least one of: patient physiological data, patient characteristic data, and rescuer performance data; receive timing information of the medical treatment information from the first medical device; record the medical treatment information and the timing information; and transfer, upon detecting a connection to the second medical device, the medical treatment information and the timing information to the second medical device.

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR).

A wound or incision closure apparatus comprises a first and second panel. Each of the panels comprises a bottom adhesive layer, a medial substrate layer, and an upper load distribution layer which connect the two panels. A sensory or therapeutic element is disposed adjacent, within, or between two or more of the layers. The sensory or therapeutic element can provide sensing and/or therapy for the incision and/or monitor the incision so that the therapy can be customized and updated.

Systems and methods regarding ventilation of a patient, such as a victim at the scene of an emergency are described herein.
