A patient support system with chest compression system and harness assembly with sensor system. The harness assembly secures shoulders and hips of the patient on a patient support surface during transport. A chest compression system is integrated into the harness assembly in a manner that provides chest compressions to the patient while the patient is secured on the patient support surface. The tension of the harness assembly is selectively adjusted and/or a fluid bladder may be selectively expanded. A controller is in communication with the chest compression system and controls operation of the chest compression system. The sensor system is integrated into the harness assembly and in communication with the controller. The chest compression system may be removable from the harness assembly via an adapter. The chest compression system may be integrated into the patient support apparatus to secure the patient to the patient support surface while providing chest compressions.

A medical device configured to be adhesively coupled to an external surface of a subject, and to facilitate physiological monitoring of the subject, includes: a first portion having a housing that at least partially encloses an interior chamber and has a grip portion that has a peanut-like shape; and a second portion including a flexible patch configured to facilitate operably coupling the first portion to the subject. The flexible patch includes third and fourth sensor connections configured to operably interface with the first and second sensor connections, respectively; first and second sensing elements; and a flexible circuit assembly configured to electrically couple the third sensor connection to the first sensing element and the fourth sensor connection to the second sensing element. An adhesive assembly is configured to couple the first portion to the second portion, and includes conductive adhesive portions.

Methods and system for guiding a rescuer in placement of a defibrillation electrode may include initializing one or more cameras disposed on the defibrillation electrode, and capturing image information via the one or more cameras. Each image in a series of images may be acquired by the cameras after a set time interval. The method may include determining a separation distance between the defibrillation electrode and the chest of the patient and comparing the separation distance to a threshold distance. The method may further include determining whether the separation distance is below the threshold distance and, once the separation distance is below the threshold distance, determining a current location of the defibrillation electrode based on the series of images, and providing positioning feedback via at least one output device, wherein the positioning feedback includes instructions to move the defibrillation electrode toward a preferred location on the patient.

Representative embodiments of the present invention provide for novel, minimally invasive implantable devices and methods for targeted tissue drug delivery of cardiovascular drugs.

An electrode for long term wear includes a conductive mesh configured to disperse a therapeutic current across a surface area of the electrode, and a conductive adhesive material configured to conduct the therapeutic current from the conductive mesh in a direction substantially orthogonal to the surface area of the electrode. The conductive adhesive material is configured to be semi-conductive in a direction substantially lateral to the surface area of the electrode. The conductive adhesive material includes at least one of microscopic or nano-scale conductive particles or fibers of materials.

In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one electrocardiogram (ECG) electrode, at least one acoustic sensor, and at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one therapy electrode. The at least one processor can receive at least one acoustic signal from the at least one acoustic sensor, receive at least one electrode signal from the ECG electrode, detect at least one unverified cardiopulmonary anomaly using the at least one electrode signal, and verify the at least one unverified cardiopulmonary anomaly with reference to data descriptive of the at least one acoustic signal.

An electrode patch for use with an external medical device, the electrode patch comprising: a first surface configured to be attached to a skin of a patient monitored by the external medical device, and an indicating mechanism disposed on the electrode patch and configured to indicate an end of a predetermined lifespan of the electrode patch.

A wearable cardiac monitoring and treatment device includes a garment, a plurality of ECG electrodes, a plurality of therapy electrodes, a therapy delivery circuit, and one or more sensors configured to monitor one or more physiological signals of the patient. The device also includes a controller configured to detect an arrhythmia condition, cause the therapy delivery circuit to deliver one or more therapeutic pulses to the patient on detecting the arrhythmia condition, detect that the garment is no longer worn about the torso of the patient prior to expiration of at least a prescribed duration of wear by detecting a loss of signal for at least a threshold period of time from one or more of the plurality of ECG sensing electrodes and/or one or more of the one or more sensors, and issue a notification that the garment is no longer worn about the torso of the patient.

A ventilation monitoring system for assisting in proper placement of an endotracheal tube in a subject includes: a capnography sensor configured to be placed in fluid communication with the endotracheal tube and to provide information representative of the subject's breath; and a processor in communication with the capnography sensor. The processor is configured to provide an indication of proper endotracheal tube placement when (1) a first indication of the subject's breath and a positive result of a first auscultation are identified within a first predetermined time period, and (2) a second indication of the subject's breath and a positive result of a second auscultation are identified within a second predetermined time period. The first auscultation includes auscultation of a subject's left lung, right lung, left axillary region, right axillary region, or abdomen. The second auscultation includes auscultation of another region of the subject different from the first auscultation.
