Patent number: 11957504Abstract: Non-invasive blood pressure (NIBP) systems and methods are disclosed that measure a blood pressure, and in some examples a beat-to-beat blood pressure, of a patient without restricting blood flow. The NIBP systems determine an efficacy of administered cardiopulmonary resuscitation (CPR) to the patient based on the measured blood pressure and are able to optionally output the CPR efficacy or generate user prompts based on the CPR efficacy. Further, the disclosed NIBP systems can generate user instructions to administer further treatment to the patient based on the CPR efficacy.Type: GrantFiled: May 24, 2021Date of Patent: April 16, 2024Assignee: Stryker CorporationInventors: Clinton T.

Publication number: 20220219000Abstract: Techniques are described for pacing assistance and automation. For example, a pacing device, such as an external defibrillator, provides electrical stimulations to an external surface of a patient based on a determination as to whether capture has been achieved. The pacing device determines whether capture has been achieved using multiple types of sensor data and/or historical sensor data. These techniques effect a particular treatment (e.g., pacing using an external pacing system) for a medical condition (e.g., bradycardia). In some examples, the pacing device provides notifications to assist with pacing to a healthcare provider that is administering pacing to a patient. Notifications may include an indication that multiple representations corresponding to different biological parameters of a patient may assist with pacing, that the patient has an internal pacemaker, and so forth.Type: ApplicationFiled: January 6, 2022Publication date: July 14, 2022Inventors: Robert G. Walker, Blaine Krusor, David J. Linville, Daniel W. Piraino, Joseph L. Sullivan, Tyson G. Taylor

Publication number: 20220193433Abstract: Systems, devices, and methods for detecting and addressing irregular motion to improve defibrillation shock recommendations are described. In an example method performed by a medical device, an electrocardiogram (ECG) of an individual receiving chest compressions is detected. In addition, irregular motion of the individual is detected. If a magnitude of the irregular motion is greater than or equal to a threshold, a remedial action is performed. In some examples, the medical device refrains from generating a recommendation indicating whether the ECG includes a shockable rhythm and/or whether a defibrillation shock is recommended. In some instances, the medical device outputs the recommendation with a certainty of the recommendation. In some cases, the medical device outputs a warning and generates the recommendation in response to receiving an input signal indicating a manual override.Type: ApplicationFiled: December 22, 2021Publication date: June 23, 2022Inventors: Fred W. Chapman, Ryan William Apperson, Steven Barry Duke, Michelle Liu, Thangeswaran Natarajan, Daniel W. Piraino, Tyson G. Taylor, Robert G. Walker

Publication number: 20220193430Abstract: Defibrillators providing enhanced recommendations of whether to administer a defibrillation shock to patients are described. An example defibrillator determines an analysis factor, such as whether a patient has previously exhibited high-amplitude or “coarse” ventricular fibrillation (VF) during a particular time period. The defibrillator generates a shock index based on an electrocardiogram (ECG) of the patient and determines whether the patient is exhibiting a shockable rhythm by comparing the shock index to a threshold. The defibrillator generates the shock index and/or the threshold based on the analysis factor. The defibrillator outputs a recommendation based on the determination of whether the patient is exhibiting the shockable rhythm.Type: ApplicationFiled: December 22, 2021Publication date: June 23, 2022Inventors: Fred W. Chapman, Daniel W Piraino, Tyson G. Taylor, Robert G. Walker
