An active backboard that can assist with adjusting a patient on the backboard to ensure that the backboard is correctly aligned for a compression mechanism of an upper portion of a mechanical cardiopulmonary resuscitation (CPR) device to perform compressions. The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard.

Various techniques related to post-treatment parameters of patients are described. An example method includes identifying a segment of an electrocardiogram (ECG) of an individual, wherein the segment is detected during a time interval that begins when an electrical shock is output to the individual's heart. The method further includes identifying a parameter of the electrical shock and generating a report including the segment of the ECG and indicating the parameter of the electrical shock. The report is output or transmitted to an external device.

Techniques for identifying and analyzing events-of-interest indicated by physiological parameters

The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

System and method for electrocardiogram analysis and optimization of cardiopulmonary resuscitation and therapy delivery

An example method is performed by a computing device executing instructions stored in data storage, and includes receiving physiologic monitoring data from a plurality of sensors coupled to a patient, receiving information indicating a measurement of patient motion during the patient care event, determining whether the measurement of patient motion is above a threshold, based on determining whether the measurement of patient motion is above the threshold, generating, for the physiologic monitoring data, a respective quality indicator, analyzing, by the computing device, (i) a combination of the physiologic monitoring data from the plurality of sensors and (ii) the respective quality indicator for the physiologic monitoring data to generate a response dependent upon the combination of the physiologic monitoring data as weighted by the respective quality indicator, and based on analyzing, outputting caregiver feedback by the computing device according to the response.

Methods and systems for patient parameter fusion and feedback

An example method is performed by a defibrillator and includes obtaining event data regarding treatment provided to a patient. The method also includes obtaining a key that facilitates validating a request from a computing device to access the event data, associating the key with the event data, and transmitting the key and the event data to a server. Another example method is performed by a mobile device and includes obtaining an encoded version of an identifier of a medical device that is provided on the medical device. The medical device is configured to obtain event data regarding treatment provided to a patient. The method also includes obtaining a selection of a recipient for the event data, and causing a summary of the event data to be transmitted to the recipient.

Systems enabling doctors to access medical device data

Defibrillators with enhanced functionality during cardiopulmonary resuscitation (CPR) periods are described. The enhancements include predicting a length of a charging period of a capacitor of the medical device so that capacitor is shock charged at the end of the CPR period. The enhancements also include re-assessing an electrocardiogram (ECG) signal for continued presence of a shockable rhythm during the CPR period and before administration of a defibrillation shock. Together the enhancements can improve the timing and recommended administration of defibrillation therapy.

Defibrillators with enhanced functionality during cardiopulmonary resuscitation periods

A mechanical CPR device having one or more of a piston, a driving component configured to extend the piston toward a patient's torso and retract the piston away from the patient's torso, a controller configured to control the driving component to at least compress the patient's torso by extending the piston from a reference position to a depth and retracting the piston from the depth to the reference position, and a contact member such as one or more of a pressure pad and a suction cup attached to the end of the piston. The contact member can include a semi-adhesive material that has low adhesiveness when the controller controls the driving component to compress the patient's torso less than 60 times per minute and high adhesiveness when the controller controls the driving component to compress the patient's torso more than 60 times per minute.

A CPR machine () is configured to perform, on a patient's () chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (), and a driver system () configured to drive the compression mechanism. A force sensing system () may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (). An optional chest-lifting device () may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.

CPR chest compression machine adjusting motion-time profile in view of detected force

A CPR chest compression machine includes a retention structure that is configured to retain a body of the patient, and a compression mechanism. The compression mechanism is coupled to the retention structure and configured to perform successive compressions to the patient's chest. Various types of chest compressions may be performed on a patient during a single resuscitation event. Some embodiments also include a driver configured to drive the compression mechanism. The compression mechanism may thus perform chest compressions that differ from each other in a number of aspects, for example the depth of the compressions or the height of the active decompressions between the compressions. Some embodiments also include an adjustment mechanism. The adjustment mechanism may shift the compression mechanism with respect to the patient so that the chest compressions are performed at different locations of the patient's chest.

Cardio-pulmonary resuscitation device for compressing and decompressing the chest of a patient

In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system also includes a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. An advantage can be when the attendant checks in situations where the condition of the patient might have changed, and an adjustment is needed. Or in situations where the patient may have improved enough to where the compressions are no longer needed.

Various systems, methods, and devices related to modifying views of a multi-lead electrocardiogram (ECG), as well as identifying notations associated with the multi-lead ECG, are described. An example method includes displaying graphical elements in a first arrangement. The graphical elements respectively depict electrical signals indicative of an electrical activity of a heart. The example method further includes detecting a signal indicative of a display selection, and, based on the display selection, rearranging the graphical elements from the first arrangement to a second arrangement.

Medical device with modifiable view of an electrocardiogram

Disclosed are embodiments of a laryngoscope that facilitates targeted recording (video, or audio, or both video and audio) of time intervals associated with active laryngoscopy. In accordance with the teachings of the disclosure, a characteristic that reliably defines the interval of active laryngoscopy is used to trigger recording. One such characteristic is that the operator's hand is gripping the handle of the laryngoscope. Accordingly, preferred embodiments implement a laryngoscope having a handle so designed that when the handle is gripped by the operator's hand, recording is initiated and continued for as long as the operator's hand maintains a grip on the laryngoscope handle.

Laryngoscope with handle-grip activated recording

A medical device can include a housing, an energy storage module within the housing to store an electrical charge, and a defibrillation port to guide via electrodes the stored electrical charge to a person in need of medical assistance. The medical device can also include a processor to analyze patient physiological signal(s) that indicate heart viability. Positive measures of heart viability measures can qualify the patient for a customized treatment paradigm.

Determining post-shock treatment based on heart viability

The disclosed physiological feedback systems and methods assist with assessing, monitoring and/or treating a patient experiencing a cardiac arrest event. The systems and methods receive multiple inputs and are continuous and/or iterative during a treatment session to provide physiological state trends of the patient. An index of the physiological state of the patient can be derived and confounders, and/or their effects, can be identified, and/or removed, from the index. Additionally, the systems and methods can assist with determining ischemic injury in a patient based on cerebral tissue oxygenation and/or other physiological data.
