An example of a system for providing patient care guidance to a caregiver based on ultrasound detection of blood flow includes a defibrillator including an electrode assembly and an output device, a portable computing device communicatively coupled to the defibrillator and including an output device, a Doppler shift waveform evaluation engine disposed at the defibrillator and/or the portable computing device, and a wearable ultrasound blood flow sensor configured to couple to a patient and the defibrillator and/or the portable computing device and to generate data signals representing a Doppler shift waveform. The engine is configured to receive the data signals representing the waveform, generate caregiver instructions according to a cardiac arrest protocol, analyze the waveform based on the received data signals, identify heart-induced blood flow based on the waveform analysis, and generate and provide caregiver instructions according to a non-cardiac arrest protocol based on the identified heart-induced blood flow.

A system is provided for resuscitative therapy to a patient by delivering active chest compression decompressions. The system may include an ACD device configured to be coupled to the patient's chest and constructed for a rescuer to press and pull on the ACD device to administer active compression decompression therapy. Additionally, the ACD device may include at least one sensor for sensing at least one active compression decompression parameter, processing circuitry configured to process the at least one active compression decompression parameter and provide an output based on the at least one parameter, a first communication circuit configured to transfer data related to the processed output of the at least one parameter, and a second communication circuit capable of being removably coupled to either the electrode assembly or the ACD device.

An apparatus and method is provided for a defibrillator that specifies treatment protocols in terms of number of chest compressions instead of time intervals. The defibrillator includes a connection port that is configured to attach with a plurality of electrodes that are capable of delivery of a defibrillation shock and/or sensing one or more physical parameters. An energy storage device capable of storing a charge is attached to the plurality of electrodes. A controller is coupled to the plurality of electrodes and the energy storage device, the controller is configured to provide CPR chest compression instructions in terms of the numbers of CPR chest compressions.

A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method offers guidance throughout a cardiac rescue protocol involving both defibrillation shocks and CPR that improves the effectiveness of the rescue, resulting in more CPR “hands-on” time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

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.

A portable medical treatment apparatus and interactive application that leads a user through a medically acceptable query flow for treating medical emergencies, including cardiac or pulmonary medical emergencies that can be treated with electrotherapy and other medical emergencies.

An automated cardiac massage device has two dynamic, multilayered compressive units oriented to compress the heart using an outer, non-compliant layer which supports an inner layer made of expandable and compressive material configured to contract and expand to facilitate cardiac filling and ejection. The compressive units are attached to a flexible apex member which modulates the shape and position of the two compressive units to provide maximal apposition to the heart while the device remains in use. Barometric pressure sensors may be incorporated on the inner layer of the compressive unit to measure the systolic and filling diastolic pressure within the heart. A third, detachable, phalange arises from the flexible apex member to provide a third station of support for the heart should the configuration of the compressive units require an additional point of support to secure the heart within the apparatus.

The invention disclosed here relates in general to the field of medical devices. In particular, to devices and methods for improving the clinical outcome of patients suffering from cardiac dysrhythmias without cardiac arrest. This method and/or device integrates mechanical, pneumatic, acoustic and/or electrophysiologic capabilities with electrical countershock or pacing capabilities such that the probability of successful cardioversion or pacing is increased. The sequence, forces, and electrical properties of the subsystems can be computer controlled and adjusted in response to biomarker inputs.

A respiration device (1) supports cardio-pulmonary resuscitation (CPR) and a method for operating a respiration device (1) supports cardio-pulmonary resuscitation (CPR). The respiration device (1) has a control and regulation unit (7) in order to actuate an expiratory metering unit (3), and an inspiratory metering unit (2) such that, in a first phase, a current value of pressure is increased relative to a first pre-defined value (16) and such that, in a second phase, the current value of the pressure is reduced relative to the first pre-defined value (16).

A system for facilitating resuscitation includes: a first electrode assembly having a therapy side and a first motion sensor; a second electrode assembly having a therapy side and a second motion sensor; processing circuitry operatively connected to and programmed to receive and process signals from the first and second motion sensors to estimate at least one of a chest compression depth and rate during administration of chest compressions and to compare the chest compression depth or rate to a desired range; and an output device for providing instructions to a user to administer chest compressions based on the comparison of the estimated chest compression depth or rate to the desired range. One or both of the electrode assemblies may be constructed so that the conductive therapeutic portion is able to maintain substantial conformance to the anatomy of the patient when coupled thereto. For example, at least a portion of the flexible electrode pad may be able to flex from a more rigid sensor housing, or the sensor housing itself may be relatively small compared to the flexible electrode pad so as not to cause lift off of the therapeutic side from the patient.
