The system includes an adhesive pad configured to be adhered to at least a portion of a patient's chest, a sensor configured to be placed on the patient's chest and to measure at least one chest compression parameter during CPR treatment, and a landing pad having a coupling surface at least partially surrounding the sensor and configured for maintaining adherence with an active compression decompression device, the adherence sufficient to transfer decompression force between the active compression decompression device and the patient's chest during the CPR treatment.

A medical monitoring and treatment device that includes a therapy delivery interface, a plurality of therapy electrodes coupled to the therapy delivery interface, a plurality of electrocardiogram sensing electrodes to sense electrocardiogram signals of a patient, a sensor interface to receive the electrocardiogram signals and digitize the electrocardiogram signals, and at least one processor coupled to the sensor interface and the therapy delivery interface to analyze the digitized electrocardiogram signals, to detect a cardiac arrhythmia based on the digitized electrocardiogram signals, and to control the therapy delivery interface to apply electrical therapy to the patient based upon the detected cardiac arrhythmia. The at least one processor is further configured to analyze a frequency domain transform of the digitized electrocardiogram signals, to determine a metric indicative of a metabolic state of a heart of the patient, and to accelerate or delay application of the electrical therapy based upon the metric.

The invention relates to a device (10) for selective regionalization of pulmonary aeration, intended to apply a vacuum over a posterolateral part of a patient's chest wall, said device comprising a rigid or semi-rigid shell (11) intended to selectively surround a posterior part of the patient's chest wall, and a layer of honeycomb material (12) covering an internal wall (13) of the rigid shell, intended to be in contact with the patient's chest wall, said shell comprising at least one through hole (14), intended to be connected to a negative pressure generator.

A mechanism attached to a mechanical CPR device can be automatically attached to the patient's torso. The mechanical CPR device can extend the mechanism to a first position at which the mechanism comes into contact with the patient's torso. The mechanism can be further extended until a first threshold is reached. The mechanism can be retracted to the first position. The mechanism can be further retracted from the first position until a second threshold is exceeded. The mechanism can then be extended to a second point at which the second threshold is no longer exceeded. The mechanism may comprise a suction cup or sticker plate, and may be attached to an end of a piston of the mechanical CPR device.

A suction cup on the end of a piston of a mechanical CPR device can be automatically attached to a patient's torso. The mechanical CPR device can extend the piston until a first position at which the suction cup comes into contact with the patient's torso. The piston can be further extended to cause air to be forced out from an area between the suction cup and the patient's torso until a first threshold is reached. The piston can be retracted until the suction cup is at the first position. The piston can be further retracted from the first position until a second threshold is exceeded. The piston can then be extended to a second point at which the second threshold is no longer exceeded.

A system for assisting cardio-pulmonary resuscitation (CPR) treatment of a patient includes a defibrillator system including a defibrillator communicatively coupled to a local computing device and configured to receive signals from treatment sensors, a patient support section, and a tilt adjuster coupled to the patient support section. The tilt adjuster is configured to communicatively couple with the defibrillator system, receive a control signal indicative of a target tilt angle from the local computing device, and automatically tilt the patient support section, around a transverse axis, to the target tilt angle in response to the control signal from the local computing device. The system also includes a chest compression device mount disposed on the patient support section and configured to adjustably secure a chest compression device to the patient support section.

A plunger adapter and a detachable compression pad for piston driven chest compression devices optimizes the application of chest compressions to a fixed location on a patient's chest. The detachable compression pad may be removably secured to the patient above the patient's sternum to ensure that the compression pressure from the piston through the piston adapter is applied to a fixed location on the patient's chest. As the plunger and plunger adapter retract from the chest, the compression pad remains fixed to the patient's chest, and as the plunger and plunger adapter extend from the chest compression unit for subsequent compression strokes, the distal end of the plunger adapter reengages the compression pad to apply compression to a fixed location on the patient's chest.

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.
